Established in 1908 Schnorr has pioneered the production and applications for their high quality discs springs.

Natural developments are their ranges of bearing preload springs and safety washers.

With more than 100 years experience Schnorr products are now used in a wide range of demanding applications in the aerospace, automotive, electrical marine and rail industries.

Their many long standing customers include:

• ABB
• Airbus
• BAE Systems
• Bosch
• Daimler Chrysler
• Siemens
• TATA Steel

Schnorr discs springs are manufactured to EN16983 and EN16984 from high quality spring steels. When required heat or corrosion resistant materials such as Inconels and Nimonics are used.

The standard range of approximately 250 sizes has outer diameters from 6 to 250mm.

A major advantage of using Schnorr is their knowledge and understanding of the stresses at work in a disc spring.

Their expertise in the manufacture and heat treatment of their springs ensures that they are particularly suitable for dynamic loadings – a common area of failure for less well-made springs.

Their engineering experience enables Schnorr to supply tailor made solutions to suit a customers exact needs – particularly in applications that require a long service life combined with dynamic stress.

Over time more than 12,000 special variants have been made – the largest 80mm thick – many of these are calibrated stacks to a specific requirement.
