Chrome Steel Drawn Cup Needle Roller Bearing

Needle Roller Bearing

1. Material: Chrome steel
2. Type:

A. Drawn Cup Needle Roller Bearing

Bearing NO.: HK, BK, HK...2RS, HK...RS, BK...RS, FFH, MF, MFH, FY, MFY, etc.

It is for a thin outer ring of needle roller bearing stamping molding. Its main characteristic is a low sectional height and higher load capacity. It is mainly used in bearing configuration with compact structure and inexpensive price and inside hole of bearing case could not be used as needle roller cage assembly. Bearing and bearing case shall be installed to interfere with. If it can save the axial positioning function such as shoulder and snap ring, then, the inside hole of the bearing case could be made simple and economic.

B. Radial Needle and Cage Assemblies

Bearing NO.: K/KS, KK/KKS, KZK, KBK, KNL, etc.

It's a unique bearing units of a high load capacity and high rigidity design. It is especially suitable for parts in which the shaft and seat hold can be used directly as roller and radial size is restricted. Needle roller bearing cage assemblies for connecting rod is applied in medium and small internal combustion engine.

C. Needle Roller Bearing

Bearing NO.: NK, NKS, RNA49, RNA48, N49...RS, NA49...2RS, RNAO, NAO etc.

It is a rolling bearing combined of above-mentioned two or more bearing structures. It is the bearings of smallest radial section positioning or one-way positioning. It's used in transmission engineers and machine tools such as drilling machine, centering axis, drill sets, worm, CNC machine, die head spindle bearings and similar applications.

D. Yoke Type Track Rollers

Bearing NO.: RTO, RSTO...X, STO, RNA22...2RS, NA22...2RS, NA22...2RSX, NATR, NATR...PP, NATV, NUTR, NUTR, etc.

It is of thick outer ring. With the outer ring, the rolling wheels can roll in the rolling trail directly, and can withstand large loads. It includes pressure rollers, eccentric rollers, roller rocket, etc. The shape of rollers are cylindrical or spherical. Using spherical outer ring tilt position can be compensated during installation.

Curve wheel is composed of a bolt as the raceway in the roller group and a thick outer ring. The should of bolt shaft and end face check ring on it compose guide surface along the side of the two directions. When the curve wheel moves in flat rolling trail or cam plate, due to elastic deformation of the outer ring and increased internal stress of the roller, therefore used in the context or such work load rated wheel column selected as the curve.

E. Thrust needle roller and hold cage assembly

Bearing NO.: AXK, K811^TN, K812^TN, LS, AS, WS, GS etc.

Thrust needle roller and hold cage assembly or thrust cylindrical roller bearing is configuration of needle roller( roller) in a roller washers. The cage clamp reliably guide and carry a lot of rollers. The rollers in the same group only have slight difference. Thrust needle roller and hold cage assembly or thrust cylindrical roller bearing can only support bearings of one direction axial load. It can be used as bearing configuration of good rigidity and occupying smallest apace. If the surface machine of adjoining parts can be used as rolling trail of needle rollers and hold cage assembly, bearing configurations can be extremely compact. If the program can not be implemented, under circumstances of enough supporting space, using AS series washer can get a very small axial section height. Combined with thicker LS, GS, WS, ZS series washers, it's also effective used in different demanding occasions.

3. Grade: P0, P6, P5, P4,

4. Packing: Single colour boxes, industrial packing.
