China Factory 20*52*15mm NU304ECP NU304 Steel Cage Single Row Cylindrical Roller Bearing

Description China Factory 20*52*15mm NU304ECP NU304 Steel Cage Single Row Cylindrical Roller Bearing    Cylindrical roller bearings are precision bearings, consisting of a cage, rollers and guide shaft rings. They can be separated from another bearing ring and are separable bearings. This kind of bearing is more convenient to install and disassemble. Compared with other types of bearings with the same outer dimensions, Cylindrical roller bearings have the characteristics of high load, low noise and high speed, and the friction between the rolling element and the ring rib is small, so it is suitable for Rotate at high speed. N type: The inner ring has two integral flanges and the outer ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself. The bearings are therefore used as non-locating bearings. NU type: The outer ring of bearings of the NU design has two integral flanges and the inner ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself. NJ type: The outer ring has two integral flanges and the inner ring one integral flange. The bearings are therefore suitable for the axial location of a shaft in one direction. NF type: The outer ring has one integral flange and the inner ring two integral flanges. NUP type: The outer ring has two integral flanges and the inner ring one integral flange and one non-integral flange in the form of a loose flange ring. The bearings can be used as locating bearings, i.e. they can provide axial location for a shaft in both directions. RN type: No outer ring and the inner ring two integral flanges. NN type: NN type bearing without ribs on outer ring,there is a wall in the midel of between both sides of inner ring. It can make shaft relative bearing between the axial displacement generated in both directions.
