A, single-railing angle contact ball bearings
and tapered roller bearings back to back mounting, between the two bearings, the length difference between the outer spacer is adjusted to adjust the preload (or gap). The tapered roller bearing is adjusted to 0 gaps or very small gaps.
B. The single column angle contact ball bearing can be equipped with a double bearing in a certain preload group.
C. The inner hole has a taper cylindrical roller bearing
its preload can be achieved by an inner ring with a tapered amount of the shaft.
D. The preload load of the bidirectional thrust angular contact ball bearing can be adjusted through the length of the internal spacer.
e, high-speed angular contact ball bearings
typically reach an axial preload load with a spring.
