Overview of Needle roller bearings

Needle roller bearings are roller bearings with cylindrical rollers, with long and thin rollers is needle roller.Although has the small section, the bearing still has the high load bearing capacity, the needle roller bearing is equipped with the thin and long needle roller, therefore the radial structure is compact, its inside diameter size and the load capacity is the same as other types of bearings, the outer diameter is the smallest, especially suitable for the radial installation size is limited the supporting structure.

According to the use of different occasions, can be used without inner ring of the bearing or needle roller and cage components, at this time to suit the bearing surface of the surface of the shaft and the shell hole directly as inner and outer rolling bearing surface, in order to ensure the load capacity and operation performance and you have the same ring bearing, axis or shell hole hardness on the surface of the raceway, machining accuracy and surface quality should be as a bearing ring raceway.This kind of bearing can bear only radial load.

Features of Needle roller bearings

Needle roller bearings are equipped with thin and long rollers, so the radial structure is compact, the inside diameter size and load capacity are the same as other types of bearings, the outer diameter is the smallest, especially suitable for the radial installation size of the limited supporting structure.

Applications of Needle roller bearings

Roller needle roller bearing is suitable for printing machinery, forage machinery, agricultural machinery, CNC equipment guide rail roller, conveyor line, etc.

The type of Needle roller bearings

Drawn cup

The stamped outer ring needle roller bearing is a needle roller bearing with a thin stamped outer ring.Its main characteristic is that the section height is very low and the load bearing capacity is high.Mainly used in compact, inexpensive bearing configurations where the inner hole of the bearing box cannot be used as a raceway for needle cage assembly.

Entity ferrule

The solid ring needle roller bearing is composed of one or two rings and a needle roller group with a cage.According to the different application occasions, it can be divided into bearings with or without inner ring.
