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.

 

Needle bearing application:

 

We are a professional manufacturer of four main types of needle roller bearings. The products are applied to areas such as textile machinery, printing machinery, tobacco machinery, engineering machinery, sewing machinery, food-processing machinery, packing machinery, motorcycles, mopeds, power tools, automobiles, office equipment, auto-laundry machines and mining machinery.
