Due to choose high precision cylindrical roller (needle) increased contact length, enables the bearing in a small space can get high load capacity and high stiffness. Another advantage is that if the adjacent parts surface suitable for groove surface can save gasket, can make the design is compact, DF thrust needle bearings and cylindrical roller thrust bearing the needle and cylindrical roller YuanZhuMian of repairs to form surface, can reduce edge stress and improving service life
