Zusammenfassung:	The utility model provides an inner-ring double-rib angular-outer-ring rib-free oil groove oil hole precise bearing. The premise bearing comprises a rib-free oil groove oil hole outer ring made through adopting SKF-3# steel, a double-rib angular inner ring, a split reinforced nylon 66 injection molded retainer and a ceramic roller, and the bus of the ceramic roller has a logarithmic curve shape with the middle having a smaller convexity degree and with the two ends having larger convexity degrees. The precise bearing is mainly used on a machine tool main shaft, and can reach the performance requirements of high precision, high rotating speed, low temperature increase, low noise, high rigidity and long life of precise machine tool main shaft bearings.
