1. Material: Chrome steel
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 c
