The radial structure of the needle roller bearing is compact, and its inner diameter size and load capacity are the same as other types of bearings, and the outer diameter is the smallest, which is especially suitable for the support structure with a small radial installation size. Can only bear radial load. When selecting rolling bearings without inner ring or outer ring, and without inner and outer rings, the hardness, machining accuracy and surface quality of the shaft or housing hole surface as the raceway should be similar to the raceway of the bearing ring to ensure the load capacity and The running performance is the same as that of a bearing with rings.
    The structural types of needle roller bearings include single row, double row K type, stamping M type, engineering plastic cage, double half split type, engineering plastic cage structure, etc. The convexity processing of the rolling surface of the needle roller, the surface strengthening treatment of the cage, and the non-uniform distribution of the needle window holes are other technological features. Gearbox needle bearings are often used in conjunction with needle bushings.
    DOBTOP can produce needle roller bearings of various structures, which are suitable for automotive gearboxes, universal joint supports, rear axle suspensions and other mechanical selections.DOB
