  • Bearing cage, also known as bearing retainer, is one of the main parts of the bearing. The function of the bearing cage is to wrap and isolate the rolling elements and move with them, and usually also has the function of guiding the rolling elements.

    The main function of the bearing cage

    1. Keep an appropriate distance between the rolling elements to prevent the rolling elements from contacting each other to reduce friction;

    2. Make the rolling elements evenly distributed, so that the load is evenly distributed;

    3. Guide the rolling elements in the no-load area to improve the rolling conditions in the bearing and prevent destructive sliding.
