Product Description
Stainless Steel Angular Contact Ball Bearing 7317B Precision Ball Bearing
Description:
The raceways of both the inner and outer rings of these non-separable bearings are made with set contact angles. The balls are inserted using counter-bore construction, which allows a larger number of balls to be installed than in deep-groove ball bearings. Single-row angular contact ball bearings can sustain radial, axial and momentary loads. However, any axial load must be applied in one direction. Due to their design, angular contact bearings will experience some amount of axial loading from any radial load that is applied. For this reason, they are often used in pairs.
