Shims and Spring Washers
GRW: quality in perfection.
Shims are often used to balance tolerance chains and axial tolerances attributable to production engineering reasons.
GRW shims are made of corrosion-proof steel 1.4310, are heat-treated, burr-free, and have an extremely fine surface finish.
Spring washers are used for defined axial pre-loading of roller bearings, in particular miniature and small ball bearings. Bearing spring washers take up internal clearance, and can reduce vibrations and decrease bearing noise, improving wear life.
The production process consists of cutting and punching processes. For special requirements, subsequent calibration, and additional finishing with highly accurate preload tolerances can be implemented.
GRW spring washers are preferably made of corrosion-proof steel 1.4310, are heat-treated, burr-free, and have an extremely fine surface finish. As a standard feature, our spring washers have 3 waves and thus ensure an even support of the bearing during axial preloading.
