Bearing cage

Bearing cage, also called bearing retainer, refers to the bearing part that fully or partially encloses the rolling elements and moves with them to isolate the rolling elements and usually guide the rolling body and keep it in the bearing. Bearing cages are divided into metal cages and non-metallic cages (Nylon, PTFE, plastic cage) by material type. There are also composite material cages.
