Needle rolling and cage assembly

The needle roller and holder assembly is an independent rolling element, with a wide distance between the two guide surfaces of the holder, which can accurately guide the needle roller and maintain its correct position. This type of bearing is suitable for situations where the shaft and seat hole can be used as raceways. By machining the shaft and bearing seat hole raceways to the specified dimensional and geometric accuracy, high rotational accuracy in small spaces can be ensured.
