Single row circular cone needle bearings can bear radial load and the single direction axial load. When bearing radial load, axial force component, would create a so when need another affordable bearing axial force in the opposite direction to balance.

    Needle roller bearing is mainly used to bear the joint mainly consisting of radial load and axial load. Compared with the angular contact ball bearing, large carrying capacity, limit rotational speed is low. Needle roller bearings can withstand axial load in one direction, can limit axial displacement of shaft or housing in one direction.
    2.The Advantage of Needle Roller Bearings:

    1.Strong abrasion capability

    2.Competitive price
    3.Low cross section. Low Noise and long life
    4.High Precision and load capacity.
    5.Various types are available
    6.Reliable quality
    7.OEM is accepted
    8.Various design and Widespread use.
