What are the Needle Roller Bearing?
The 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.
