Textile Bearing Needle Roller Bearings

Needle roller bearings are roller bearings with cylindrical rollers,and the rollers are both thin and long relative to their diameter.

This type of roller is called a needle roller. Despite having a small cross-section,the bearing still has a high load bearing capacity. Needle roller bearings are equipped with thin and long rollers (roller diameter D≤5mm,L/D≥2.5, L is the roller length), so the radial structure is compact. When its inner diameter size and load capacity are the same as other types of bearings, the outer diameter is the smallest, making it particularly suitable for support structures with limited radial installation dimensions.

The solid ring needle roller bearing is composed of machined outer ring,inner ring and cage and needle roller.It has small cross-section height,large load capacity and rigidity,compact structure and small volume.This kind of bearing can provide two series of products,metric and British.Each series has three types of structure:cage type,full needle type and sealing type.In addition,solid ring bearings can be divided into two structures:inner ring and non-inner ring.
