What is a Needle roller bearings?

Same cylindrical rollers are the rolling elements of needle roller bearings. They are designed to reduce friction of a surface which is in rotation. Due to its shape, the needle bearing has a larger surface are a that is in contact with the outer surface of the bearing.

Axial needle bearings are flat and a radial pattern while the radial needle bearing have a cylindrical shape and the rollers run parallel to the axis of the shaft.

Where could we found DEMY Needle roller bearings ?

Needle roller bearings consist of an inner race(shaft), needle cage, needle rollers and an race. The rollers are cylindrical, thin, and long. These bearing are compact because there is less clearance between the diameter of the shaft and that of the bearing, This quality makes them suitable for situations where is limited radial space.
