Abstract

Prior art miniature bearings of the type shown in Fig. 1 have high assembly and part costs and require a relatively hard shaft. Shaft 1 is spring-biased through opening 2 in jewel bearing 3 such that rounded end 4 is urged against jewel end stone 5. Jewels 3 and 5 are carried by plastic housing 6.

Miniature Bearing Construction

Prior art miniature bearings of the type shown in Fig. 1 have high assembly and part costs and require a relatively hard shaft. Shaft 1 is spring-biased through opening 2 in jewel bearing 3 such that rounded end 4 is urged against jewel end stone 5. Jewels 3 and 5 are carried by plastic housing 6.

Cost and shaft hardness requirements are reduced by molding a plastic housing around segments of a spring steel strip. In Fig. 2, housing 9 is molded to strip 10 with a shaft opening 8 and a void 7. Void 7 is to insure contact between shaft 1 and strip 10. Following molding, the segments of strip 10 are separated at the break tabs 12 (Fig. 3).
