Axial spherical roller bearings are single row, self-aligning roller bearings. They comprise solid shaft and housing locating washers and asymmetrical barrel rollers with cages. The cage holds together the roller and cage assembly and the shaft locating washer. The bearings can be dismantled. As a result, the bearing components can be fitted separately.

Axial and radial load capacity:
Axial spherical roller bearings can support very high axial loads and allow relatively high speeds. Since the raceways are inclined relative to the bearing axis, the bearings can also support radial loads.

Compensation of angular misalignments:
Axial spherical roller bearings can be swivelled about their central position by a few degrees. As a result, they permit skewing between the housing and shaft locating washer and can thus compensate misalignments, shaft deflections and housing deformations.
The adjustment angles given in the table are permissible under the following conditions.
*P or P0 ≦ 0,05 · C0a
*the angular deviation is constant (static angular misalignment)
*the rotating component is the shaft locating washer.
The lower values are valid for large bearings.

Permissible skewing:
292..-E   1°- 1,5°
293..-E1(-E)   1,5°- 2,5°
294..-E1(-E)   2°- 3°
If the rotating component is the housing locating washer or the shaft locating washer undergoes tumbling motion, the angular adjustment facility is smaller.

Sealing: 
Axial spherical roller bearings are not sealed.

Lubrication: 
The bearings are not greased. They are generally lubricated using oil. In some cases, lubrication with greases containing EP additives is also possible. Adequate supply to the contact points between the rollers and guidance rib is best achieved if the bearings are completely filled with grease.

Operating temperature: 
Axial spherical roller bearings can be used at operating temperatures from –30 °C to +200 °C, restricted by the lubricant.

Cage: 
Bearings with the suffix MB have a solid brass cage that is guided on the shaft locating washer. The other bearings have sheet steel cages and do not have a cage suffix.

Suffix:
E, E1:  Increased capacity design
MB: Solid brass cage
