NBB  centripetal needle roller and holder unit is independent rolling elements, the space between the two guiding surfaces of the holder is wide which can not only guide the needle roller but also can keep the correct position of the needle roller. This series is used in the situation when the axis and seat bore are treated as bearing race. High rotated precision with mini space can be assured only to process the axis and bearing seat bore into stated dimension precision and geometric accuracy.
