Cylindrical roller and the raceway is in line contact bearings. Load capacity, mainly bear radial load. Rolling ring wall friction is small, suitable for high-speed rotation. According to ring without ribs, it can be divided into NU, NJ, NUP, N, NF and other single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearings. The bearing inner ring, outer ring separable structure.
No inner or outer wall of the cylindrical roller bearings, the inner and outer rings can be relative to the axial movement, so it can be used as a free end bearings. In an inner and outer side of a double-wall, the other side of the ring has a single wall of the cylindrical roller bearings, can withstand a certain degree of axial load direction. General use of steel stamping cage, or copper alloy solid cage. But there are also part of the use of polyamide forming cage.
