1.The Description of Needle Roller Bearings:

Needle roller bearing type belongs to the separation bearing, have needle roller bearing inner and outer race. According to these bearings on the column number of the needle is divided into single row, double row and four row circular cone needle bearings of different structure. Single row circular cone needle bearings can bear radial load and the single direction axial load. When bearing radial load, axial force component, would create a so when need another affordable bearing axial force in the opposite direction to balance.

Needle roller bearing is mainly used to bear the joint mainly consisting of radial load and axial load. Compared with the angular contact ball bearing, large carrying capacity, limit rotational speed is low. Needle roller bearings can withstand axial load in one direction, can limit axial displacement of shaft or housing in one direction.
2.The Advantage of Needle Roller Bearings:

1.Strong abrasion capability

2.Competitive price
3.Low cross section. Low Noise and long life
4.High Precision and load capacity.
5.Various types are available
6.Reliable quality
7.OEM is accepted
8.Various design and Widespread use.

3:The definition of Needle Roller Bearings:

Capacity single row needle roller bearing axial load depends on the contact angle, the outer ring raceway angle, the greater the angle, the greater the axial load capacity. Needle roller bearings is the largest amount of single row needle roller bearings. In the car's front wheel hub, and use the small size of the double row needle roller bearings. Four-row needle roller bearings used in large-scale cold rolling mill and other heavy machines.

4:The Application of Needle Roller Bearings:
