About Radial Ball Bearings

The most commonly used style of rolling bearing, radial ball bearings have a row of balls that glide on curved raceways between the bearing's internal surfaces. They are recommended for applications where parts are under radial loads (where the load is perpendicular to the axis of rotation of the bearing) but can also tolerate low to moderate axial, or thrust, loads (where the load is parallel to the axis of rotation of the bearing).

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.

The outer ring of these bearings is flanged to help you position them axially and mount them to the housing.
