While the raceways of radial and angular-contact ball bearings are parallel to the shaft, allowing them to support radial loads (where the load is perpendicular to the shaft), the raceways of thrust ball bearings are perpendicular to the shaft, so they are able to sustain axial, or thrust loads (where the load is parallel to the shaft) but not radial loads. Thrust ball bearings are a good choice for supporting rotating parts in applications with light loads where misalignment is unlikely.
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.
Use these bearings for a wide variety of standard applications.

An outer band holds these bearings together and provides more resistance to dust and other contaminants than general-purpose bearings.
