Single row cylindrical roller bearings with cage are units comprising with solid inner and outer rings and cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or no ribs, the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents cylindrical rollers from coming into contact with each other during rolling.
The cylindrical roller bearings with cage have high rigidity, high radial load carrying capacity and, due to the cage, are suitable for higher speeds compared to full complement designs. Bearings with the suffix E have a higher capacity roller set by internal design optimization and are thus designed for very high load carrying capacity.
The bearings are separable and are therefore easier to fit and dismantle. Both inner and outer rings can be given a tight fit by this process.
Single row cylindrical roller bearings with cage are available as non-locating, semi-locating and locating bearings.
KMR bearings have lower roughness Ra and higher geometrical accuracy of the raceways than standard designs. As a result, KMR bearings have higher load carrying capacity and longer service life for the same dimensioning. In certain applications, this means that a smaller bearing arrangement can be designed.
