Needle Roller Bearing

Needle Roller Bearing

Needle roller bearings are a special type of roller bearing which uses long, thin cylindrical rollers resembling needles. Ordinary roller bearings’ rollers are only slightly longer than their diameter, but needle bearings typically have rollers that are at least four times longer than their diameter.

Compared to ball bearings and ordinary roller bearings, needle bearings have a greater surface area in contact with the races, so they can support a greater load. They are also thinner, so they require less clearance between the axle and the surrounding structure.

Needle Roller Bearings are:

  • capable of carrying radial loads
  • suitable for low and medium speed applications
  • mainly used in gearbox, steering, clutch, differential, engine, UV joints, etc. in automobiles
