NJ205 NU205 Cylindrical Roller Bearings

Product Details

Cylindrical rollers and raceways are linear contact bearings. Large load capacity, mainly bearing radial load. The friction between the rolling element and the ferrule flange is small, which is suitable for high-speed rotation. According to whether the ring has a flange, it can be divided into NU, NJ, NP, N, NF and other single row cylindrical roller bearings, andNNU, NN and other double row cylindrical roller bearings. The bearing is a separable structure for the inner and outer rings.

Cylindrical roller bearings with no flange in the inner or outer ring, the inner and outer rings can be moved relative to each other in the axial direction, so they can be used as free end bearings. Cylindrical roller bearings with double flanges on one side of the inner and outer rings and a single flange on the other ring can accommodate a certain degree of axial load in one direction. Generally, steel stamped cages, or copper alloy turned solid cages. However, some use polyamide forming cages.
