Characteristics and application

RNA, NK type needle roller bearings, this type of bearing has no inner ring, it is suitable for the support structure with limited radial installation size, and the journal matched with the bearing is directly used as the rolling surface. As the shaft of the raceway surface, the hardware must be hardened and ground, and only when it is processed to the appropriate size and shape accuracy, the entire set of needle roller bearings can have a high life and running accuracy. At the same time, since there is no inner ring, the diameter of the shaft can also be appropriately enlarged, thereby increasing the rigidity.

Application

Needle roller bearings are widely used in many fields due to their large aspect ratio, compact structure, and strong load-bearing capacity. In the automotive industry, the piston pin of the engine, the shift fork shaft of the transmission, and the seat adjustment mechanism all rely on it to assist in efficient power transmission and flexible operation of components; In industrial sewing machines, needle roller bearings support the high-speed spindle and shuttle, ensuring precise and smooth sewing movements; The motor rotor and gearbox of electric tools rely on them to cope with high speed and frequent start stop, improving tool durability; In addition, in precision transmission systems of aerospace equipment, compact space transmission mechanisms of agricultural machinery, and even small drive components of office equipment, needle roller bearings play an indispensable role in stabilizing and supporting the operation of various machinery with their own advantages.
