Description
Brief Introduction:
A needle roller bearing is a bearing which uses small
cylindrical rollers. They are used to reduce friction of a rotating
surface.
Needle bearings have a large surface area that is in
contact with the bearing outer surfaces compared to ball bearings.
Additionally there is less added clearance (difference between the
diameter of the shaft and the diameter of the bearing) so they are
much more compact Needle bearings are suitable when the rotational
speed is relatively low.
