Cylindrical Roller Bearings series NU/NJ/N248/NUP

Detailed Product Description

Cylindrical roller and the raceway for the wire-contact bearing. Load capacity, mainly bear radial load. Rolling body and ferrule wall friction is small, suitable for high-speed rotation. According to whether the ribs ferrule can be divided into NU, NJ, NUP, N, NF and other single row bearings and NNU, NN, etc. double row bearings. The bearing is the inner and outer rings detachable structure. No inner or outer wall of the cylindrical roller bearings, the inner and outer rings can be made to the axial relative movement, so it can be used as a free-side bearing. In the inner and outer rings of a certain side of the double-wall, on the other side of the ring with a single wall of the cylindrical roller bearings, can withstand a certain degree of axial load in one direction. General use of steel stamping cage, or copper alloy cage car system. But there are also a part of shaping the use of polyamide cage.
