About Angular-Contact Ball Bearings

The raceways of these angular-contact ball bearings have high and low shoulders. The high shoulders of the inner and outer raceways oppose each other, which directs axial, or thrust loads (where the load is parallel to the shaft) through the bearing in one direction. Double-row bearings act like a pair of back-to-back single-row bearings, and can support axial loads in two directions. Angular-contact ball bearings are recommended for applications with moderate to high radial loads (where the load is perpendicular to the shaft) and low to moderate axial loads.

Ball bearings have spherical rolling elements that distribute loads over a small surface area, and they typically create less heat and friction and tolerate higher speeds than roller bearings. To ensure proper functioning, bearings should be lubricated regularly.
