Angular Contact Ball Bearings | Ball Bearings | Products .

The NSK range of angular contact ball bearings has been designed to meet the increasingly demanding requirements of original equipment manufacturers. These bearings have a contact angle so that they can sustain significant axial loads in one direction together with radial loads.

Bearing Internal Clearance and Prelo

Bearing Internal Clearance and Preload 8.1 Bearing internal clearance Bearing internal clearance is the amount of internal free movement before mounting. As shown in Fig. 8.1, when either the inner ring or the outer ring is fixed and the other ring is free to move,

Angular contact Ball Bearing - koyo.

The preload can be built into the bearing or created when the bearing is inserted into an assembly. The contact angle varies from 15° to 40° and is measured relative to a line running perpendicular to the bearing axis. Angular contact bearings are unidirectional thrust bearings that can withstand heavy thrust loads and moderate radial loads.
