Gebrüder Reinfurt Würzburg has been developing and manufacturing high-precision ball bearings for more than 50 years. During this period GRW delivered several hundred million ball bearings of the very highest quality to all corners of the world. The most diverse demands on precision and functionality are met with short development times, modern production methods and fast reactions to tight delivery dates All ball bearings are manufactured with rolling bearing tolerances according to DIN 620, accuracy classes P0 to P2, and AFBMA Standard ABEC1 to ABEC9, in conformance with the respective ISO standards. Moreover ball bearing's quality and functionality is guaranteed by special design characteristics and functional tests.
GRW specializes in the production of miniature deep groove ball bearings made of fully hardened rolling bearing steel and stainless steel. The standard range covers ball bearings from 1 to 17 mm bore and 3 to 40 mm outer diameter, in metric and inch sizes. We also manufacture ball bearings with flanged outer ring, extended inner ring and various types of retainer and shield. Model types include separable and non-separable angular contact ball bearings, spindle ball bearings, duplex bearings, hybrid bearings (steel rings with ceramic balls), and fully ceramic bearings. In addition GRW also manufacture bearing units and special ball bearings based on standard parts in order to minimize development times and hence development costs.
