Application

HK、BK Series

There are two types of perforated type and sealed type. Drawn cup needle roller bearings have no inner ring, and the needle directly contacts the surface of the shaft, so the machining accuracy and heat treatment hardness of the shaft should be the same as the inner ring of the bearing.

Drawn cup needle roller bearings with cages are suitable for high speed and heavy loads, and are mostly used in gearboxes for machine tools, automobiles, and motorcycles or textile machinery. The stamped ferrule needle roller bearing without cage, because it is full of needle rollers, is practically used for swing working conditions under heavy load. Such as the frame of the aircraft, the shaft end of the main wing of the missile, etc.

NA、RNA Series

Entity ferrule needle roller bearings are mostly used in machine tools and automobile gearboxes. Its advantages are small radial cross-sectional dimensions and large radial loads. The standard-type solid ring needle roller bearings have cages, so the speed is higher, which can be suitable for the requirements of machine tools and automobile gearboxes.
