A ball bearing, esp. for hte bearing pin of hte winding roller of a roller blind, fits its inner ring on to the pin and the outer rotating ring has an inside groove to hold the balls safely, but freely. The outer ring is a thermoplastic material and is pref. heated before being ...
The circular foot (50) supports a ball bearing (80) which a lower race (823) accommodating balls (83) which in turn support an upper race (813). A large diameter disk (60) has a groove (62) in the underside accommodating a flange on the upper race and has a central bore (61). ...

According to the shallow groove radial ball bearing, the groove depth is reduced, and the containment friction area of a ferrule groove to each ball is diminished; the shallow groove radial ball bearing is very favorable for the reduction of the energy consumption of the bearing, starting of ...
