Angular Contact Ball Bearings - an overview | ScienceDirect Topics

In angular contact ball bearings the line of action of the load, at the contacts between balls and raceways, forms an angle with the bearings axis. The inner and outer rings are offset to each other and the bearings are particularly suitable for carrying coined radial and axial loads. The single row bearing is of non-separable design

Internal clearance | SKF | SKF

Bearing internal clearance ( fig. 1) is defined as the total distance through which one bearing ring can be moved relative to the other in the radial direction (radial internal clearance) or in the axial direction (axial internal clearance). In almost all appliions, the initial clearance in a bearing is greater than its operating clearance.
