The centripetal needle roller and cage assembly (needle bearing) is an independent rolling element, with a wide spacing between the two guide surfaces of the cage, which can accurately guide the needle and maintain the correct position of the needle. This type of bearing is suitable for situations where the shaft and seat hole can serve as a raceway. Simply machining the raceway of the shaft and bearing seat hole to the specified dimensional and geometric accuracy can ensure high rotational accuracy in the minimum space.
