Plastics roller bearing cage - has open circumference with spring steel wire ring producing radial location force when assembled

摘要

A plastic roller bearing cage in its unmounted condition has an axial slot in at least one position along its circumference. When assembled and located, this slot disappears so that the cage is radially sprung against axial movement. The side section (5) of the cage (1) has at least one spring steel open wire ring (8) located in a groove (7) in the front face of the cage. ADVANTAGE - Maintained spring force over bearing life, good stiffness even with large cages.
