Physical ring needle roller bearing is composed of one or two rings and needle roller cage with the composition of the group. Depending on the application, can be divided with or without inner ring of the bearing inner ring. Therefore, entities ring needle roller bearings to meet light weight, small footprint, passing power requirements. Physical ring needle roller bearings with a smaller size and a higher carrying capacity. Physical ring needle roller bearings NA, NKI-type bearings without inner ring is the RNA, NK-type, single-sided or double-sided sealed needle roller bearings with or without inner ring sealed needle roller bearings can effectively prevent dirt invasive NX17Z needle roller bearings, has filled the right amount of lithium bearing grease. This kind of bearing inner ring outer aspect ratio, which makes the bearing axis relative to the bearing box with a little displacement but also to ensure a good seal to prevent injury to the bearing contamination. The inner bearing lubrication hole also can be configured according to the NX20 needle roller bearings, lubricated by the outer or inner complement drawn cup needle roller clutch is the use of thin-walled high-quality steel stamping machining precision punching outer ring, with the corresponding plastic cage, consisting of one-way clutch springs and needle can pass unidirectional torque.
