ABIS Preload Springs For ball bearings

Preloading of bearings is a crucial process that involves applying an axial load to either the inner or outer ring of the bearing. This ensures that radial play is taken up, and running components are in consistent contact. Using a bearing preload spring is seen as a best practice as it significantly reduces noise and vibration, ultimately extending the life of the bearing.

There are essentially two methods to preload a bearing. Firstly, a solid preload, such as a threaded plug or circlip. Secondly, by a spring, specifically a disc spring. The disadvantage of a solid preload is that it cannot compensate for tolerance build-up or thermal expansion of the surrounding components, which may affect the running torque.

Bearing preload springs, particularly disc springs, offer a superior solution. The disc spring, by applying a constant load around the bearing ring, overcomes the limitations associated with solid preloads. In applications where a very light preload is required, the disc spring can be designed with radial slots to reduce the axial force applied.

IEC provides a comprehensive range of bearing preload springs from ABIS, designed to meet various application requirements. Our springs ensure consistent performance and reliability by maintaining optimal contact and load distribution in ball bearings.

Benefits of ABIS Bearing Preload Springs

Noise Reduction: Preloading reduces operational noise, leading to quieter machinery.
Vibration Control: Minimises vibration, improving overall equipment stability.
Extended Bearing Life: Reduces wear and tear, extending the bearing’s lifespan.
Thermal Compensation: Accommodates thermal expansion and tolerance variations, maintaining consistent performance.

Abis Miniature Ball Bearings Structure

Ball bearings benefit over plain bearings in terms of torque levels, rotational accuracy and speed capability. In their standard form they can support both radial and axial loads.

Basic rules for selection & handling of bearings

Selection

The efficiency of miniature or thin section bearings can be greatly affected by the precision of shaft and housing seats. The accuracy of the surrounding must be such that it will not adversely affect the operation of the bearing. If you have any questions, in particular regarding series 6700 and 6800, please contact us.
In applications with steel crown type cages (W type), where high acceleration, heavy loads, shock loads or vertical shafts occur or where oil is the only lubricant available, please contact us.
Selection of fitting clearance and grease type requires a careful consideration of rotating speed, load conditions and temperature in order to prevent premature bearing failure.
Full complement ball bearings are suitable for low speed and heavy radial load conditions. There is a danger of ball being pushed out of the bearing through the filling slot, even under light axial load. For this reason, full complement ball bearings are not suitable for supporting axial loads.

Handling

The actual assembly area should be kept free from dust as any contamination has a detrimental effect on the operation and life of rolling bearings. If there is any doubt concerning the cleanliness of a bearing, it can be washed with a suitable agent and then re-lubricated.
When bearings are being fitted care should be taken to ensure that the ring concerned is presented squarely to the mating surface and that any fitting load required is applied via the ring being fitted – NOT UNDER ANY CIRUMSTANCES FROM ONE RING TO THE OTHER THROUGH THE BALLS. If it is necessary to heat the bearing to facilitate fitting, the temperature should not exceed +120^oC.
After assembly, the bearing should be rotated to check its correct operation. If the bearing does not appear to be functioning correctly, it should be re-examined to establish the cause of the malfunction.
It is not advisable to mix oils and greases as this will affect the efficiency of the bearing.
Bearings must be stored in a clean environment with stable temperature. They should be handled with care to avoid the possibility of corrosion and rusting.
Lint-free cloth must be used to wipe shaft and housing seats to avoid the ingress of contaminants into the bearing.

Design & characteristics of radial ball bearings

In the majority of applications the size of the ball bearing is selected according to space considerations. Usually the load capacity which the selected bearing provides is more than adequate for the continuous loads to which it is subjected. In extreme cases, or which severe vibration or shock loading is known to occur, the load carrying capability should be checked.

The form which the bearing takes is entirely determined by the overall design philosophy.

Open or closed – is the bearing likely to become contaminated? Is escape or outgassing of lubricant an issue?

Normal or extended inner – is there sufficient clearance axially between rotating and stationery components?

Load – single low radial ball bearings with balls separated by a cage can support radial loads, axial loads and tilting moments. A full complement V-type ball bearing can support only radial loads and some low axial loads.Generally a full complement bearing is used when a higher radial load is required than the standard bearing provides.

Speed – maximum permissible speeds for ball bearings are mainly related to the bearing design and size, cage type, bearing internal clearance, method and type of lubrication, manufacturing accuracy, sealing methods and loads.

Torque and noise level – single low radial ball bearings are precision components and have low torque and noise levels.

Inclination or inner/outer rings – shaft and housing seats with poor accuracy, fitting errors and shaft bending might cause inclination between the inner and outer rings although the internal clearance of the bearing will permit this to a certain extent. Generally, the maximum permissible inclination between the inner and outer rings is approximately 1 in 300.

Toughness – bearings under load deform elastically at the contact point between the rolling element and bearing ring. This is influenced by the bearing type, size, form and load.

Installation and removal – the single row radial ball bearing is a non-separable bearing. Therefore, shafts and housings should be so designed to enable bearing inspection and replacement when necessary.

Axial location – improved axial location is obtained with Thrust type bearings.

Two important internal parameters which must be considered and specified when a bearing is selected are:

Radial play & internal clearance – the total diametrical movement from contact at one side between rings and balls to similar contact at the other side. It is normally stated in increments of tenths of a thousandth of an inch or microns. This parameter effects the torque level, the axial movement, the load carrying capacity, especially in an axial direction and, according to installation, the noise level and smoothness of the bearing.

Lubrication – the choice of oil or grease and the particular type of each, has an influence on the bearing performance. Noise level, speed, environment temperature, load and life are some of the various factors which should be considered when selecting lubricant.

Installation

To obtain the best performance, certain basic rules should be observed in the installation.

Keep Parts Clean

The clearance involved between the balls and tracks is very small and so any dirt particles present in the area of the tracks cause rough, noisy rotation and perhaps even permanent damage.

Keep Components Round

The inner and outer rings are generally of fairly thin section and no mating parts must be of good roundness to prevent distortion of the rings with consequent inaccurate rotation and roughness.

Keep Assemblies Shockfree

Since radial loads are supported on several contact points, shock loading can result in permanent deformation of the tracks and balls. The resulting craters again give rough, noisy rotation.

ABIS Lubricants

Lubrication of a bearing serves to:

Eliminate metal to metal contact
Reduce friction
Minimise temperature increase
Improve low torque characteristics
Reduce noise level
Prevent corrosion

Two major forms of lubricant are available—oil and grease.

Oil

In general, oil is used as a lubricant where grease is unsuitable, for example, where low torque or high speed are considerations. Typical oils used are the same as those used as the base oils in greases. The operational life of oils is usually much less than that of equivalent greases due to evaporative losses. One exception is the perfluorinated hydrocarbon family of oils that have extremely low saturated vapor pressure (SVP), giving greatly extended life.

Grease

Grease lubricant is comprised of a base oil carried in a thickening agent, which delays migration and evaporation of the oil, lengthening its effective operational and shelf life. Additives may also be included in the basic grease formula to improve corrosion resistance, reduce oxidation, and otherwise improve the lubricant performance. Grease lubrication is recommended unless low torque or high speed is essential to the application.

ABIS Miniature Ball Bearing Materials

The standard material for ABIS rings and balls is a vacuum degassed high carbon chromium steel allowing for high efficiency, low torque, low noise level and long bearing life. For bearings requiring anti-corrosion or heat-resistant properties, martensitic stainless steel is used.

ABIS Miniature Bearing Noise Testing

Bearing acoustical noise is a function of both the bearing itself and the way in which it is used. Bearings can be specified as 100% noise-tested during manufacture. Bearing noise is not generally influenced by ABEC precision, but rather by manufacturers’ internal quality standards, particularly raceway finish. There are no fixed reference standards among manufacturers for noise testing.

Noise Testing

The standard instrument used for bearing noise testing is the Anderon Meter (sometimes called Anderometer) made by Sugawara Laboratories. This measures noise with an accelerometer contacting the outer race of the bearing while the inner race is rotated at 1,800 RPM. Noise levels are separated into 3 bands, designated as follows:

High band 1,800 – 10,000 Hz
Medium band 300 – 1,800 Hz
Low band 50 – 300 Hz

According to the type of bearing (material and noise grade), a different attenuation is used for each band. Meters are calibrated in Anderons. Standard testing procedure requires that bearings are washed clean of any lubricant and 2 drops of fresh MIL-L-6085A oil lubricant added prior to testing.

Typical attenuation values for each band are given in the table below, according to bearing material and noise grade. A “pass” for any bearing grade is defined as < 40% of full scale on the Anderon meters for each band. In this case, this translates to pass levels of Low < 6.4, Med < 2.4, High < 3.2.

Abis Bearings RETAINER Cages

The retainer, also referred to as the cage or separator, is used to separate and position the balls at equal intervals around the bearing raceways. Retainers are available in two standard types, according to the size and design of the bearing itself. The most common is a 2-piece closed ball pocket design known as a ribbon retainer. The crown retainer is a single piece open ball pocket design.

W One-Piece Steel Crown Type	J Two-Piece Steel Ribbon Type	RJ Two-Piece Steel Rivet type	TW One-Piece Nylon Crown Type	V Full Complement of Balls
The stainless steel pressed cage is inner ring guided. It shows excellent performance in low torque, low speed applications.	Consists of two mating steel pressings, the cover side and the finger side. Usually guided by the rolling elements and designed to reduce frictional torque.	The RJ type case is suitable for larger bearings with a high load carrying capacity. The two pieces are riveted together and are strong enough to withstand higher levels of vibration and acceleration. The cage is guided by the balls and reduces frictional torque.	Moulded nylon cage. Reduces the fluctuation in running torque. Suitable for high speeds. Guided by the rolling elements. NYLON CAGE operating temperature range from -30 to +120^oC.	This type of bearing has no cage but maximum possible number of balls. Due to the fact that the inner and outer ring have a filling slot, the axial load carrying capacity of this bearing type is low. This type of bearing is suitable for high radial load, low speed applications.

Closures

A shield (non-contact) or seal (contact) is often installed to retain lubricant and to prevent contamination from entering the bearing raceways. These are available in a variety of materials and configurations.

ZZ Pressed Steel Shield	ZZS Steel Shield with Snap Ring	TTS Teflon Seal with Snap Ring	2RS Contact Rubber Seal	2RU Non-Contact Rubber Seal
Non-contact shield pressed into outer ring. Very little grease leakage and low ingress of contaminants.	Non-contact shield retained in outer ring. Low ingress of contaminants. Mainly used for smaller or narrower bearings.	Teflon seal reinforced with glass fibre is retained in outer ring by snap ring. Low ingress of contaminants. Mainly used for smaller or narrower bearings. Seal can flex to accommodate internal pressure changes. TEFLON SEAL operating temperature range from –100 to +260^oC.	Rubber seal fitted into outer ring. Light contact with inner ring, retains grease and prevents ingress of external contaminants. NBR SEAL operating temperature range from –40 to +120^oC. FKM (VITON) SEAL operating temperature range from –30 to +230^oC.	Non-contact rubber seal fitted into outer ring, still provides effective sealing. NBR SEAL operating temperature range from –40 to +120^oC. FKM (VITON) SEAL operating temperature range from –30 to +230^oC.

ABIS Bearings Radial Play

The radial play of a bearing has considerable influence on its performance. Therefore consideration must be given to the speed, temperature, load, adjacent materials (different coefficients of expansion) and fitting conditions associated with each individual application when selecting the appropriate group. The following notes are given for guidance against the various groups details in the table below:

ABIS Bearings Internal clearance

This is generally referred to as radial play although it also incorporates axial play as well because it is actually the amount of space between the rolling elements of the bearing, namely inner ring, outer ring and balls.

Radial Play – is clearance perpendicular to the axis of the bearing and better described as the movement available to the outer ring when inner is fixed. This can be more accurately defined as follows: average diameter outer ring raceway minus average diameter of inner ring minus x2 ball diameter.

Axial Play – is the opposite of radial play as it is the movement of the rings relative to each other along the axis of the bearing. The amount of axial play is controlled by the bearing raceway curvature but as a general rule is around x10 the value of radial play.

Radial play is a major consideration when selecting a bearing. Prior to fitting a bearing has an ‘initial’ amount of play and after being mounted it has a ‘residual’ radial play (sometimes referred to as operational radial play as it is what is remaining). When a shaft is supported between bearings then consideration needs to be given to the alignment of the bearings as misalignment reduces radial play, therefore it is important that selection accounts for this. There should always be some ‘residual’ radial play after fitting as this extends bearing life by avoiding skidding and reducing axial play. There are a number of things that can change radial play during fitting. A tight shaft, larger than the inner ring, will expand the inner ring and this can reduce radial play up to 80% of the interference fit. The same thing happens if the outer ring is larger than the housing diameter, the ring is effectively compressed and reduces radial play in the same way. If there was a temperature difference seen between the shaft and the housing then thermal expansion either on the inner or outer ring, would lead to a reduction in radial play. This may be calculated as opposite: Chrome Steel – 0.0000125 x (inner ring temp – outer ring temp °C) x outer ring raceway diameter in mm. 440 Stainless Steel – 0.0000103 x (inner ring temp – outer ring temp °C) x outer ring raceway diameter in mm. The outer ring raceway diameter is roughly calculated as: 0.2 x (d + 4D) where d is the bore in mm and D is the outer diameter in mm. Another factor to consider relating to thermal expansion is the material that is used for the shaft and housing. For example, a housing material with a higher coefficient of expansion than the bearing material could under certain conditions ‘squeeze’ the bearing outer ring and reduce radial play.

Importance of correct fitting of bearings

A bearing can only perform to its full capacity when it is correctly fitted on the shaft and in the housing. Insufficient interference on fitting surfaces could cause bearing rings to creep in a circumferential direction. Once this happens, considerable wear occurs on the fitting surface and both shaft and housing can be damaged. Furthermore, abrasive particles may enter the bearing causing vibration, excessive heat and damage to raceways. It is therefore necessary to provide bearing rings under rotating load with an adequate interference fit to prevent creep. When using thin-type bearings under low load, the bearings should be fastened by a nut. Statically loaded bearings generally do not need to be fitted with an interference fit. Only when subject to a high degree of vibration do both inner and outer rings require fitting with an interference fit.
