Cylindrical roller bearings are produced in many designs, ISO Dimension Series and sizes. The vast majority are single row cylindrical roller bearings with a cage. These bearings are an excellent choice for applications where there are particularly heavy radial loads combined with high speeds, especially if there is a limited amount of axial displacement of the shaft with respect to the housing as a result of thermal elongation. As axial displacement takes place within the bearing, there is practically no increase in friction as the bearing rotates. Single row cylindrical roller bearings are separable, i.e. the ring with roller and cage assembly can be mounted independently of the other ring. This simplifies installation, particularly if an interference fit is required for both rings. Single row cylindrical roller bearings with a cage are produced in many designs, differing primarily in the configuration of the flanges. The rollers are always guided between integral flanges on one of the rings. The ring with the integral flanges together with the cylindrical roller and cage assembly can be withdrawn from the other ring. The most popular single row cylindrical roller bearings are those of the NU, N, NJ and NUP designs.
