ABIS Basix miniature and precision ball bearings are manufactured to strict tolerances (P0-P5, ABEC 1–5) and come in a wide range of sizes from 1 mm bore to larger metric and imperial options. These bearings are available in carbon chrome or stainless steel and configurations (open, shielded, sealed) to suit diverse application needs.

The Role Of Bearings Inside ATMs

Although ATMs are often thought of as electronic devices, they rely on mechanical movement as well especially in cash handling zones. Bearings play a critical role in several ATM functions:

1. Cash Dispensing Mechanisms

Inside every ATM, cash is transported from cassettes to the customer by a series of rollers, belts and motors. Precision components such as ABIS ball bearings help these rollers turn smoothly with minimal friction and consistent motion. This not only improves speed and reliability but also reduces the risk of jams or misfeeds that can frustrate customers.

2. Motor And Drive Systems

Bearings support the motors and drive shafts that power cash dispensers, card readers, and other moving parts. ABIS precision bearings enable these motors to operate with low noise and vibration, reducing wear over time and helping ATMs deliver long-lasting performance even under heavy daily use.

3. Weather And Environment Resistance

ATMs are often located outdoors or in public spaces where temperature changes, humidity, dust and wear can stress internal components. Shielded and sealed versions of precision bearings protect these mechanisms from contaminants and help maintain performance over the long term.

The Small Spring That Solves Big Bearing Problems https://iecltd.co.uk/news/the-small-spring-that-solves-big-bearing-problems/ https://iecltd.co.uk/news/the-small-spring-that-solves-big-bearing-problems/#respond Tue, 22 Jul 2025 07:40:11 +0000 https://iecltd.co.uk/?p=19681

In high-speed machinery, precision isn’t optional. Even tiny amounts of axial play in ball bearings can lead to unwanted noise, vibration, and wear. And when thermal expansion comes into play, keeping preload consistent becomes even harder.

That’s where K Springs from Schnorr Washers— made in Germany and distributed in the UK by IEC — make the difference.

Slotted K Springs
Slotted K Springs

The Challenge: Managing Preload in a Changing World

Bearings aren’t static. Heat, load changes, and manufacturing tolerances all introduce variations in assembly length. Without a way to accommodate these shifts, preload can fluctuate, leading to:

  • Noise (bearing chatter)
  • Axial play
  • Reduced bearing life
  • Increased wear

In some applications, even microns of movement can affect performance — especially in:

  • Electric motors
  • Gearboxes
  • Machine tools
  • Automotive systems
  • Robotics

The Solution: K Springs — Simple, Flexible, Effective

K Springs are designed to apply consistent axial preload on ball bearings, even when the assembly length changes due to heat or tolerances. Their slotted design allows controlled flexibility while maintaining force.

How it works:

  • K Springs fit directly into standard bearing bores.
  • One size can work across multiple bearing models — e.g., a spring for a 6302 bearing’s outer ring can also preload the inner rings of 6205 and 6305.
  • They can be stacked to adjust preload depending on design needs.
  • Both slotted and non-slotted versions are available depending on the application’s dynamics.

Key Benefits:

  • Reduces bearing noise and vibration
  • Eliminates axial play
  • Absorbs thermal expansion without significant preload variation
  • Simplifies assembly — no complex adjustment needed

Real-World Examples

  • Electric Motor Manufacturer
    A motor OEM used K Springs to eliminate axial play in a compact fan motor, reducing noise complaints in the field by 40% and extending bearing life.
  • Robotics Assembly
    A robotics customer used multiple stacked K Springs to maintain consistent preload across varying shaft temperatures, ensuring precision positioning even under dynamic load conditions.

The Result: Quiet Bearings, Longer Life, Less Downtime

In many cases, K Springs are installed once — and quietly do their job for years without attention. They are a simple solution to a complex problem, keeping bearings tight, smooth, and quiet across industries.

When Microns Matter: The Hidden Battle Inside Bearings https://iecltd.co.uk/news/when-microns-matter-the-hidden-battle-inside-bearings/ https://iecltd.co.uk/news/when-microns-matter-the-hidden-battle-inside-bearings/#respond Thu, 26 Jun 2025 09:21:39 +0000 https://iecltd.co.uk/?p=19573

You’re designing a high-precision electric motor, a robotic arm, or a compact gearbox. Everything is engineered down to the last micron. The bearings are installed, the shafts are aligned — and then you hear it.
A faint hum. A vibration. A subtle play in the shaft that wasn’t there before.

This isn’t just an annoyance. Over time, axial play can damage bearing races, generate unwanted heat, and lead to premature failure. The cause? Thermal expansion, manufacturing tolerances, and dynamic loading — all shifting the preload on your bearings.

That’s exactly the problem IEC helped a European automation customer solve — with Schnorr K Springs, precision-manufactured in Germany.

Slotted K Springs
Slotted K Springs

The Challenge: Preload vs Reality

Axial preload in bearings is essential for:

  • Reducing noise

  • Eliminating play

  • Preventing skidding and vibration

  • Maximising bearing life

But achieving the perfect preload is complicated. Even small variations in temperature or part tolerances can shift the axial load.

Common challenges include:

  • Shaft growth at high speeds

  • Housing expansion due to heat

  • Tolerance stack-ups in assemblies

  • Axial movement under dynamic load

And unlike many components, bearings often don’t offer second chances. A small preload loss today can lead to catastrophic failure tomorrow.

The Solution: K Springs — Small, Flexible, Reliable

Schnorr’s K Springs, distributed by IEC in the UK, are specifically designed to maintain consistent bearing preload even as assembly dimensions shift.

Key features:

  • Fits directly into bearing bores (internal diameter matched to ball bearing sizes)

  • Can preload inner or outer rings

  • Stackable for adjustable preload

  • Available in slotted and non-slotted designs

  • Compensates for thermal expansion and tolerance variations without losing preload

Why it works:

  • Axial flexibility absorbs expansion without significant force variation

  • Prevents bearing play across the full temperature and load range

  • Simplifies design — no complicated shimming or constant readjustments

Real-World Applications

Electric Vehicle Traction Motors
An EV manufacturer was experiencing noise issues at high RPM due to shaft growth under heat. By integrating K Springs, they maintained stable preload on motor bearings across wide temperature swings, eliminating NVH (noise, vibration, harshness) issues.

Industrial Robotics
A robotics OEM used K Springs to maintain bearing stability in high-speed pick-and-place arms. Without them, rapid cycling caused preload loss and positional inaccuracies. K Springs absorbed dimensional changes while preserving precision.

Precision Gearboxes
In a high-speed gearbox design, stacked K Springs were used to absorb expansion and ensure continuous preload across varying operating temperatures — critical for maintaining gear mesh accuracy under full load.

The Result: Silence, Stability, and Service Life

Thanks to their precision engineering, Schnorr K Springs quietly solve one of the most frustrating challenges in bearing assemblies — keeping preload stable, even when everything else moves.

With IEC’s engineering support and Schnorr’s German-made quality, design teams across Europe have a simple, reliable solution for complex bearing assemblies.

How Fuji Lock Nuts Keep High-Speed Gearboxes Tight and Track-Ready https://iecltd.co.uk/news/how-fuji-lock-nuts-keep-high-speed-gearboxes-tight-and-track-ready/ Wed, 07 May 2025 08:24:36 +0000 https://iecltd.co.uk/?p=19200
high speed cars

From Pit Lane Problems to Precision Engineering

 You’re building a high-speed performance car, engineered for 300+ km/h. Everything is tightened to spec, the engine roars to life, and then—mid-race—a gearbox nuts comes loose. Not a big one, just a small bearing preload fastener. But that tiny flaw? It costs you the race. Or worse—the gearbox.

That’s exactly the kind of problem a European motorsport engineering firm brought to IEC, the official UK distributor for Fuji Lock Nuts. Their brief was clear: “We want a fastener that doesn’t quit at 10,000 RPM.”

Fuji bearing lock nut with visible grooves and threads, used for securing bearings and shaft components.
IEC offer a range of Fuji Fine U-Nuts

 The Challenge: Vibration Is the Silent Saboteur

The client’s six-speed sequential gearbox was a masterpiece—compact, light, and brutally efficient. But like all great machines, it had an Achilles heel: vibration-induced loosening. No matter the torque spec or locking fluid, bolts in the gearbox housing and shift linkage kept walking themselves out—especially under track conditions.

 Symptoms of the Problem:

  • Shift forks misaligned mid-session
  • Bearings coming loose
  • Evidence of galling on bolts
  • High pit-lane maintenance time

Race cars can’t afford mistakes. This wasn’t just an annoyance—it was a DNF waiting to happen.

racing team

The Solution: Fuji Lock Nuts – Small Nuts, Big Impact

IEC introduced the team to Fuji’s FUJILOK Fine U-NUT, an all-metal lock nut with a unique self-locking friction ring—no nylon inserts, no adhesives, just pure mechanical resistance. The Fine U-Nut is designed specifically to preload bearings-precisely and without washers.

Why It Works

  • Friction ring design: Generates controlled torque as it tightens
  • All-metal construction: Withstands heat that would melt nylon nuts
  • Self-locking without extras: No need for washers or thread-lockers
  • Compact & reusable: Ideal for race gearboxes with high service cycles

And here’s the fun bit: in Fuji’s internal vibration tests, the FUJILOK Fine U-NUT lasted 30,000 cycles without loosening

Compare that to:

  • Nylon insert nuts: 3,100 cycles
  • Double nuts: 4,450 cycles
  • Regular nuts with washers: 1,335 cycles

Let’s put it this way: it outlasted the competition like Max Verstappen in a go-kart race.

Field Test: High-Speed Validation Under Real Heat

The car was sent out for a 500+ km endurance simulation on a mixed-speed track. After 3 days of testing and over 12,000 gear shifts, the team opened the gearbox…

 All nuts were still torqued. No loosening. No fretting. Just silence—the kind of silence you want from your gearbox.

The Result: Torque You Can Trust

Benefit
Outcome
Anti-vibration locking
Zero bolt failures across all test cycles
No retightening needed
Reduced pit stop time by 20%
Heat resistance
Gearbox performance held steady even under 130°C temperature
Easy installation
Mechanics loved the no-fuss torque consistency

Backed by Science and Track-Tested Wisdom

This wasn’t just a lucky fix. Fuji’s nuts have been used in over 20 industrial sectors, from motorcycles to robotics. Other case studies, like the Advanex anti-vibration nut for power plants, and Jun Fujiki’s torque diagnostics for manufacturing lines, all echo one truth:

“If it shakes, spins, or roars—Fuji keeps it bolted.”

Fuji Fastener Fun Fact

IEC has been the exclusive partner to Schnorr for products in the UK for many decades, including supplying high-performance disc springs to a range of industries. One of our most significant contributions is to the Airbus A350 programme, where our disc springs play a crucial role in various actuator systems, including the Electrical Thrust Reverser Actuation System (eTRAS). This case study explores the technical function of these components, their application within aircraft systems, and the significance of IEC’s contribution.  

Schnorr Disc Springs
IEC offer a range of Schnorr Disc Springs

The Role of Disc Springs in Aircraft Actuation Systems

Schnorr Disc Springs are used in several types of actuators and related assemblies within the aerospace industry. They are frequently employed in torque limiters to prevent overrun or reverse actuation caused by loadings. 

Disc springs serve several critical mechanical and functional roles. These precision-engineered components provide controlled force and energy absorption, ensuring the actuation system operates with high efficiency and reliability. Within aircraft actuation systems, disc springs contribute to: 

  • Load Bearing & Energy Storage: Providing preloading force to ensure controlled movement and prevent mechanical failure under extreme loads. 
  • Vibration Damping & Shock Absorption: Minimising stress on surrounding components and extending operational lifespan. 
  • Precision Control of Actuation Forces: Offering predictable load-deflection characteristics for accurate force application. 
  • Consistent Performance in Extreme Conditions: Manufactured from high-performance alloys such as 51CrV4 or stainless steel to withstand wide temperature variations. 
 
See some of IEC’s aerospace and defence engineering applications in action.

Disc Spring Requirements

The springs used in modern aircraft applications must meet stringent requirements beyond standard specifications. These include: 

  • Wide Operating Temperature Range: Necessitating the use of materials like 51CrV4 or stainless steel. 
  • High Accuracy: Often requiring two load points with tight tolerances. 
  • Customisation: Some applications specify design features not normally covered by EN 16983. 

Application Notes

Aerospace systems generally incorporate disc springs within secondary control systems such as high-lift mechanisms, engine nacelles, and landing gear. These systems rely on actuators for flaps, slats, wing tip brakes, cover opening, and thrust reversal operations.

Disc springs in actuators are also commonly used to prevent overloading and reverse operation, functioning similarly to a sprag clutch in no-back actuators. This is the case with the A350 eTRAS where the actuators are used to control the thrust reverser systems of the aircraft. Working closely with the customer, the Engineers at IEC and Schnorr developed reliable, producible springs that are outside of the normal design parameters set out in EN 16983, the spring design standard.

GRW Bearings for Satellites | Achieve Precise Orbit Simulation https://iecltd.co.uk/news/grw-bearings-satellites/ https://iecltd.co.uk/news/grw-bearings-satellites/#respond Fri, 14 Feb 2025 17:23:51 +0000 http://iecltd.co.uk/?p=18031
Satellite in orbit above Europe representing aerospace and space engineering applications

GRW Bearings for space and satellite industries provide the precision needed to simulate space conditions accurately. As satellite applications grow, frictionless motion is crucial for testing. This capability is essential for testing sub-systems such as attitude control, and positioning systems, and it enables manufacturers to simulate and analyse performance in a virtual space environment, with high accuracy.

To learn how these capabilities translate into real aerospace and aviation systems, please see our aerospace & aviation ball bearings page.

With satellites playing a critical role in various aspects of modern life, from communication and research to data collection and observation, the challenge of accurately replicating the zero-friction and microgravity environments of space on Earth is met with innovative solutions, such as those provided by IEC and GRW Bearings.

At IEC we work in unique partnership with GRW to understand and meet the needs of this market, making the bearings available in the UK, with IEC as your local source for sales and support.

How Satellite Manufacturers Use GRW Bearings for Testing

The modern era of GRW’s ball bearings for aviation, satellites, and testing devices is engineered specifically to guarantee flawless
performance and safe operation even with the complex requirements of satellite and space simulation. GRW high-precision bearings achieve near-frictionless motion by utilising advanced materials and extremely high tolerances to minimise resistance and ensure smooth operation under controlled conditions. The unique design and array of lubrication systems, from more than 300 variants, make them ideally suited even to the extremes of temperature and vacuum of space.

These capabilities are also at the heart of GRW’s newly launched high temperature bearings – the XTRA material range – designed to perform reliably from the sub-zero vacuum of space to the extreme heat of high-speed industrial applications.

Previously, satellite manufacturers relied on mathematical models and computer simulations to predict how satellites would behave in space. These models, while useful, had inherent limitations and uncertainties in accurately replicating real-world conditions, such as frictionless motion and microgravity.

With GRW ball bearings, manufacturers are able to perform physical simulations, where actual components of satellite systems are tested in laboratory settings that mimic the frictionless and microgravity conditions of space. GRW Bearings are the key to these tests because they are designed to minimise friction and resistance while operating smoothly under controlled conditions.

These simulations matter because the physical simulations, enabled by GRW Bearings, allow satellite systems such as attitude control and positioning mechanisms to be tested in a more realistic environment. This reduces the uncertainties and errors that could arise from purely theoretical models, ensuring reliable performance once deployed in space.

Ian Gritt, our TEQHS Manager, and Tina Hartley, our Purchasing and Stock Control guru, are taking on an inspiring challenge:

A 5km run in support of the Dorset and Somerset Air Ambulance charity.

Dorset and Somerset Air Ambulance is a lifeline for those in critical need. They provide pre-hospital critical care that can be the difference between life and death. Our local air ambulance charity operates tirelessly, with a team of highly skilled pilots, critical care practitioners, nurses, and doctors who are on call for 19 hours a day, 365 days a year. They reach patients in remote and challenging locations, providing essential care on the spot.
Why This Matters:

Dorset and Somerset Air Ambulance receives no direct government or National Lottery funding, relying entirely on the generosity of the public. Each mission they undertake costs approximately £3,000, and their operational costs exceed £5 million annually.

How You Can Help:

Support Ian and Tina as they run to raise funds for this vital service. Every contribution, no matter the size, makes a difference and ensures that the air ambulance can continue to save lives in our community.

Join Us in Making an Impact:

Your support can be a lifeline for someone in a critical situation. Let’s rally together and help Dorset and Somerset Air Ambulance continue their incredible work.
