A large amount of force is needed between the rotating shaft and the part that supports the rotation. Bearings perform the function of preventing damage from being done by this force to the part that supports the rotation, and also of maintaining the correct position of the rotating shaft.


Bearings are one of the most commonly used machine componets because their rolling motion makes almost all movements easier while reducing friction.bearings feature precision tolerances, proprietary internal geometries and quality materials. Our tapered, spherical, cylindrical, thrust, ball, plain, miniature, precision and housed unit bearings deliver strong performance, consistently and reliably."Bearings" are a type of mechanical part, but do you know what they do? They are, in fact, so fundamental to the machine industry that they have been called the industry's "bread and butter". They are used in all sorts of machines, but because they do their work in the shadows.
