Leheng Industry Co.,Ltd

Radial needle roller and cage assemblies is a complete bearing unit composed of cage and needle rollers. With the capability of bearing heavy load & high rigidity in the minimum radial structural space,it is mainly used as raceway in shaft and bearing box.Under high precision shaft and bracket-hole raceway, it has a very high rotating precision.Work intervals can be regulated according to the needle rollers,installing shaft and bracket hole.Convenient for installation,it is a very economical bearing applied in harsh conditions.

      As to the shaft and bracket hole which cant be quench-hardened,they can be treated by inlaying with IR standard inner ring, This product can be widely used in driving shaft,gearbox and connecting rod shaft disposition of automobile,motorcycle and engineering machinery.
 

Product Precision Accuracy:

      Mutual difference of needle rollers is 2 um,and the precision is class G2(ISO GB/T309)

The assembly nominal width Bc is -0.20 for upper deviation and -0.55 for lower deviation.

It can also be defined according to the special requirement of customers

Material:

      Material for needle roller is GCr15 bearing steel ;material for cage can be quality low -carbon steel,low-alloy steel and reinforced nylon according to different occasions and requirement.

Special Directions:

    The width of axial location is based on the assembly nominal-width Bc and conforms to the tolerance defined in H12 regulation.

When plastic cages are used(suffixed with TN) ,operation temperature is not allowed to surpass +120 during continuous work.

Standardized shaft and bracket-hole tolerance should be chosen and internal running clearance of standard radial can be achieved by utilizing standard needle rollers.
