Product feature:

The solid ferrule needle roller bearing is a bearing with a small section height and high load carrying capacity. Due to the high hardness of the outer ring, even a light alloy bearing housing can be used freely. These bearings are available in both metric and imperial series, each with a cage, full pin and sealed. In addition, the physical ferrule needle bearing can be divided into inner ring or inner ring. If the inner ring is not used, the mandrel is used as the raceway surface to make the volume smaller. The rib of the solid ferrule needle bearing is on the outer ring and may be a fixed rib or a spring lock ring. If the raceway of the mandrel is made by quenching and grinding, the detachable inner ring can be eliminated. Under normal circumstances, the needle roller bearings of NA48 and NA49 series have a row of needle rollers, and the oil groove and oil hole on the outer ring make the needle bearing lubrication more convenient.
