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 preloading of roller bearings, in particular miniature and small ball bearings. Their manufacture comprises cutting and punching processes. By means of a subsequent calibration process, additional finishing with highly accurate preload tolerances can be implemented for special applications.
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.
