About us: We are a professional Cylindrical Roller Bearings manufacturer. we are strict in the whole course from purchasing of raw materials to every process of production, our mission’s commitment is to provide client right product and right service and right delivery time.
Cylindrical rollers and raceways are line contact Cylindrical Roller Bearingss. Load capacity, mainly bear radial load. The rolling element has little friction with the ferrule rib and is suitable for high speed rotation. According to the ferrule with or without ribs, it can be divided into single row Cylindrical Roller Bearingsss such as NU, NJ, NUP, N, NF, and double row Cylindrical Roller Bearingss such as NNU and NN. The Cylindrical Roller Bearings is a structure in which the inner ring and the outer ring are separable.SL Type Cylindrical Roller Bearingss can be relubricated via the inner or outer ring. For this purpose, both Cylindrical Roller Bearings rings have an integral circumferential lubrication groove and axial lubrication holes.
