Single row radial ball bearings are the most widely used bearings and utilize an uninterrupted raceway, which makes these bearings suitable for radial loads, or a combination of thrust and radial loads. This design permits precision tolerances even at high speed operation. Sealed bearings incorporate rubber seals securely fastened to a groove on the outer ring.

The raceway grooves in the inner and outer rings are radial ball bearings that form a circular arc cross-section with a slightly larger radius than the radius of the rolling ball. Besides radial load, axial load in both directions can be loaded. Friction torque is small, and it is most suitable for applications requiring high-speed rotation and low noise / low vibration.
