Bearings

By allowing parts to move smoothly together while offering support and alignment, bearings prolong the working life of rotating components, such as a wheel on a shaft. As one of the largest distributors in North America, Partscor has over a million different kinds and sizes of bearings, including ball bearings, mounted bearings, spherical and cylindrical roller bearings, tapered roller bearings, needle bearings, cam followers, thrust bearings, rod ends, and linear bearings from the world's top brands, including SKF, Timken, Fafnir, Torrington, INA, FAG, NSK, Koyo, numerous others. In rotating or linear applications, Partscor's bearings are precise mechanical parts made to lower friction between moving parts, enabling smoother motion and increased efficiency. 

Bearings are crucial components of machines because they limit motion to a predetermined route, convey axial or radial stresses, and lessen friction between moving parts. To enable smooth, effective rotation, they are made up of an outside race, inner race, rolling elements (balls or rollers), and a cage. Failure brought on by contamination, wear and tear, or incorrect installation is avoided with adequate maintenance, which includes lubrication and sealing.

Key Types of Bearings

• Ball Bearings: The most popular kind of bearings are adaptable for high-speed, low-load applications (such as angular contact and deep groove).
• Roller Bearings: To manage larger loads, use spherical, tapered, or cylindrical rollers.
• Plain Bearings: Frequently employed for high-load, low-speed, or oscillating motion, their sliding surfaces lack rolling components.
• Thrust Bearings: Designed especially to support axial loads, or loads parallel to the shaft.
