Bearing assembling process.

Bearing assembling process. The cage is typically held in place by the inner ring of the bearing, while the balls are held in place by the outer ring. The bearing is then closed up by pressing the outer ring onto the inner ring, using a hydraulic press. This compresses the balls and cage, creating the necessary preload on the bearing. Bearings typically consist of the following components: 1.Two rings, inner and outer, with raceways. 2.Rolling elements - rollers or balls. 3.A cage which keeps the rolling elements spearted and helps guide motion.
