Needle roller bearing is a roller bearing with cylindrical rollers. Compared with the diameter, the rollers are thin and long. This kind of roller is called needle roller. With high load bearing capacity, needle roller bearing is equipped with thin and long rollers, so its radial structure is compact. Its inner diameter size and load capacity are the same as those of other types of bearings, and its outer diameter is small. It is especially suitable for supporting structures with limited radial installation size.
One way clutch, also known as overrunning clutch, is a basic component emerging with the development of electromechanical integration products. It is an important component used for power transmission and separation between the prime mover and the working machine, or between the driving shaft and the driven shaft inside the machine. It is a device with self clutch function by taking advantage of the speed change or rotation direction change of the driving and driven parts.
One way pulley assembly, referred to as OAP, is usually installed in the automobile alternator to solve the problems caused by the fluctuation of engine speed to the front end accessory drive system, improve the belt slip rate, reduce the belt vibration, tension and tensioner travel, effectively extend the life of the gear train and improve NVH. NF-OAP has higher rated torque under the same installation size……
