Introduction:

Cylindrical roller and raceway for line contact bearings. Large load capacity, mainly bearing radial load. The friction between the rolling body and the rim of the ring is small, suitable for high-speed rotation. According to whether the ring has a rim or not, 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 is a detachable structure with inner ring and outer ring.
Cylindrical roller bearings with inner or outer rings without fenders, whose inner and outer rings can move relative to each other in axial direction, can be used as free-end bearings. Cylindrical roller bearings with double rim on one side of the inner and outer rings and a single rim on the other side of the ring can withstand a certain degree of axial load in one direction. Generally used steel plate stamping cage, or copper alloy car solid cage. But some use polyamide forming cages.
