The basic structure of the rolling bearing:
Rolling
bearings generally by the inner ring, outer ring, tumbling body and
cage structure, during which the effect of sliding bearing inner ring is
matched with the shaft, and with a shaft of a composite bearing with
the rotation, the outer ring effect is matched with the bearing Support
the effect of tumbling body is through the cage evenly to the rolling
body distributed between the inner ring and the outer ring, the shape of
the size and quantity directly affect the use of rolling bearings and
the number of life, the cage can make the rolling evenly distributed, To avoid rolling roll fall, guide the rolling body rotation from the smooth effect.
