The utility model provides a cylindrical roller bearing with long service life and low friction, which belongs to the technical field of bearings, solves the problems that dust is easy to enter into the traditional cylindrical roller bearing, the lubrication is inconvenient and the shaft distance is inconvenient to adjust, and comprises a bottom plate, two groups of waist-shaped holes are arranged on the bottom plate, and a base is arranged on the two groups of waist-shaped holes on the bottom plate. A top cover is mounted on the base through bolts; the oil injection hopper is mounted on the top cover; when the bearing rotates, the brush on the brush ring is in contact with the central shaft on the inner ring, dust on the central shaft can be swept off, the dust can be prevented from entering the cylindrical rollers and the retainer, and abnormal sound is prevented from being generated when the bearing rotates; lubricating oil is added into the oil injection hopper, the lubricating oil in the oil injection ho
