Needle Roller Bearing


Needle Roller Bearing

Needle roller bearings are generally composed of needle rollers and cages. Several needle rollers are placed between two hardened and smooth surfaces and the cage prevents the needle rollers to contact each other to accommodate smooth rolling action. The diameter of the rolling element in Needle roller bearing is relatively small and has a relatively large length/diameter ratio, this allows for more load carting capacity and is ideal for oscillation motion. In comparison to other roller bearings, needle roller bearings have small radial section height and smaller mass, which allows for a more compact design and is suitable for applications where low inertia force is required.
