Needle Roller Bearing uses thin and long cylindrical rollers. They are used to reduce friction of a rotating surface.
Although it has a small section,the bearing stil has high load bearing ability. Therefore,it is especially suitable for occasion where the radial space is limited.
Needle bearings have a large surface area that is in contact with the bearing outer surfaces compared to ball bearings. Due to the less added clearance they tend to be more compact.
Needle Roller Bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited. These are widely used in engine components such as rocker arm pivots, pumps, compressors, and transmissions
