Bearings Direct is a ball bearings supplier with over twenty years of experience in the industry. Ball bearings consist of a series of round balls in a casing, within an inner and outer ring capable of supporting both radial and axial (thrust) loads. Ball bearings come in both single and double row configurations, in both metric and inch sizes, and can be found in a large range of applications from door hinges to roller skates.

There are a number of different types of ball bearings, such as miniature, deep groove, and super precision.
Miniature Ball Bearings are small bearings with bore sizes between 1 and 10 mm or up to half an inch. Bearings Direct offers a number of miniature ball bearings in both metric and inch sizes that meet ABEC7 precision class.
Deep Groove Ball Bearings are incredibly versatile and the most widely used. Due to their low friction, they are capable of high rotational speeds, supporting both radial and axial loads. Bearings Direct offers both in metric and inch sizes , also we stock stainless steel made materials metric and inch sizes
Super Precision Ball Bearings are specifically designed with accuracy in mind for high-speed and precision applications. They are capable of high rotational speeds with low friction and noise.
Precision Angular Contact Ball Bearings carry combined loads, both radial and axial, designed, much like the super precision bearings, for high-speed and high-precision applications.
Double Row Ball Bearings are similar to both precision angular contact and super precision ball bearings in that they can accommodate a combined radial and axial loads. These bearings have two rows of balls inside making them capable of much higher loads. Bearings Direct supplies double row ball bearings that are open and with shielded or sealed closures.
Self-Aligning Ball Bearings are double-row ball bearings that can adapt to both static and dynamic angular misalignment. These bearings are particularly appropriate when shaft and housing alignment is a challenge.
Thrust Ball Bearings are ball bearings that can carry axial loads alone. Bearings Direct supplies thrust ball bearings that are single row, in both miniature and regular three-piece configurations.

Thrust ball bearings are comprised of ball rolling elements. Their appearance sets them apart from the other types of bearings since the outer race and inner race, called shaft and housing washers, are layered with the cage in between. This assembly makes them look like three stacked washers. Thrust ball bearings can sustain loads at high speeds and their use are ideal for axial loads only.
Thrust Ball Bearings Applications:
