Designs and variants
Axial-radial cylindrical roller bearings can accommodate radial loads, axial loads in both directions and moment loads, whether acting singly, or simultaneously, in any combination.
These bearings consist of (fig. 1):
- Two roller and cage thrust assemblies and a full complement radial roller set.
- An inner ring which has an L-shaped cross section and two raceways. One raceway accommodates the roller and cage thrust assembly and the other accommodates the full complement radial roller set. The inner ring is drilled for attachment bolts.
- A loose flange which acts as a raceway to accommodate the second roller and cage thrust assembly. The flange is held in place to the inner ring with transport bolts that should not be removed until after the bearing has been mounted. The flange is drilled for attachment bolts.
- An outer ring which has three raceways to accommodate both roller and cage thrust assemblies and the full complement radial roller set.
The bearings are supplied standard without grease (no designation suffix) but can also be supplied greased (designation suffix G).
Bearings supplied without grease must be adequately lubricated with either grease or oil through the lubrication holes in the bearing rings. Bearings, greased at the factory, are filled with a grease that is suitable for most applications over the normal speed range for the bearing.
