Product Description

Needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length. The modified roller/raceway profile prevents stress peaks to extend bearing service life.Needle roller bearings are equipped with thin and long rollers, so the radial structure is compact.With the same inner diameter and load capacity as other types of bearings, its outer diameter is smallest, especially suitable for the support structure with limited radial installation size.

Needle roller bearings comprise machined outer rings, needle roller and cage assemblies and removable inner rings. Depending on the application, a bearing without an inner ring or a needle roller and cage assembly can be selected. In order to ensure the same load capacity and running performance as like the bearing with ring, the hardness, machining accuracy and surface quality of the raceway surface of the shaft or housing hole should be similar to the raceway of the bearing ring. This type of bearing can only bear radial loads.

Main applications:

Automobile transmission, gearbox, engine, valve train, direction and brake system, axle support, outboard engine, power tool, copy and fax machine, paper feeding equipment, etc.
