ABSTRACT:
Split journal bearings having crush relief are made by a method using a special plating rack having urethane masks for covering the ends of the split bearings during electroplating. Split thrust bearings having flanges may also be made according to the present invention by providing masking elements between adjacent bearings to prevent overplating at the flange relief areas or at the flange groove. The method eliminates broaching and/or boring operations to form crush relief areas on bearings but instead provides the required relief areas through the exclusion of overplate from said areas by masking. The plating rack features adjustable masks which are adapted to receive bearings within a range of sizes.
