Assembly of pulley wheel with integral bearing, is completed by soft soldering, hard soldering or brazing, employing capillary action to draw molten metal into gap between bearing outer ring and pulley bore

摘要

The pulley (1) is mounted on the external ring (4) of the bearing, initially as a sliding fit exerting no grip. The gap (11) is filled at least partially by molten metal, which is drawn into the interface between bearing ring and pulley by capillary action, and then sets, completing the bond.
