.Structure Types

 

Needle retainer assembly K/K...ZW/K...D/K...ZWD type series:

 

Needle roller cage assembly components related to the size of the fixed axial bearing assembly use. When using high -speed condition when the retainer and the axial limit should be added to a washer through the heat-treated in order to avoid to maintain direct contact with the limit.

 

 

.Features

- Smaller cross-section leading to greated rigidity,higher load-carrying capacity & lower inertia of the needle roller bearings help size and weight reductions in machinery.

- Though they are less wide,their load carrying capacity is high and is most suitable for applications where the load is high & the radial space is less.

- Needle roller bearings,which are designed to withstand oscillation can operate under severe conditions & interchange with sliding bearings.

. Brand: TVB or per your demand, also can be made in your own brand.

Features of Needle retainer assembly :

a. High Precision and Rigidity

b. Ease of Assembly

c. Complete range of types

d. Needle retainer assembly bearings are used in automobile, rolling mill, mining, metallurgical industry,plastic machinery, etc.

e. Special Directions
- Bearing running clearance and inner-cutting roundness should be regulated according to different conditions.
- Machine tools should be used for press-in fitting or thermal fitting of the bearing
- Limited by plastic cages (suffixed with TN) and sealing-element material, operating temperature is -300C---+1000C.
- For general disposition design of bearings, refer to the relevant recommendation in the applied

technology of rolling

bearings.

f. Other advantages of Needle retainer assembly :

.Bearing material:bearing steel Gcr15 Chrome Steel

.Smooth movement,low friction,high rigidity and long life

.Nice appearance,complete product system

.We can make non-standard needle retainer assembly bearings according to clients samples of drawing
