Abstract
A bearing retainer that holds a bearing in a bearing seat of an electromagnetic device has a unique construction that reduces its cost of manufacture. The bearing retainer has a peripheral edge with a plurality of radially extending tabs centered in gaps in the peripheral edge. The tabs connect with tabs of adjacent bearing retainers, allowing a plurality of interconnected bearing retainers to be nested on a steel sheet from which the retainers are stamped, thereby optimizing material use and reducing costs. The bearing retainers are composed of martensite which eliminates a heat tempering process required of prior art retainers and further reduces costs.
