Cylindrical Roller Bearing with Cage

Single row cylindrical roller bearings with cage are units comprising solid inner and outer rings and cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or are without ribs, the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers from coming into contact with each other during rolling.

Cylindrical roller bearings are very rigid, can support high radial loads and, due to the cage, are suitable for higher speeds than the full complement designs. Bearings with suffix E have a larger roller set and are thus designed for extremely high load carrying capacity.

The bearings can be taken apart and can therefore be fitted and dismantled more easily. Both bearing rings can therefore have an interference fit.

Single row cylindrical roller bearings with cage are available as non-locating, semi-locating and locating bearings.

X-life

Numerous sizes are supplied in the X-life grade.

Bearings of X-life quality have lower roughness Ra and superior geometrical accuracy of the raceways than comparable designs that are not X-life. As a result, these bearings have higher load carrying capacity and longer life for the same dimensioning. In certain applications, this means that a smaller bearing arrangement can be designed.
