Single-row cylindrical roller bearings with a cage comprising cylindrical rollers caged between a solid outer and inner ring. These bearings have a high level of rigidity, can support heavy radial loads and are suitable for high speeds. The inner and outer rings can be fitted separately, making installation and removal a simple process. Single-row cylindrical roller bearings are available in various designs. The most common models are NU, N, NJ and NUP. The main difference is the configuration of the ribs.
The outer ring of an NU cylindrical bearing has two fixed ribs, whereas the inner ring of the cylindrical bearing has no ribs. The axial displacement of the shaft relative to the casing can be accommodated in both directions.
