Axial cylindrical roller bearings according to DIN 722 (series 811 and 812) The versions 813, 814, 874, 893, and 894 are not standardied.
Tolerances Running, design and dimension tolerances of axial cylindrical roller bearings are equivalent to the axial bearings standard tolerances, see section bearing data. Axial minimum load Axial cylindrical roller bearings have always to operate under axial load to avoid any slip between rollers and bearing washers. If external load is too small, you may use springs to achieve a pre-stress of the bearing. The minimum axial load is calculated as follows:
Fa min minimum axial load [kN]
C0 static bearing capacity [kN]
n maximum operating speed [min-1]
ka factor, see table

-
What does the “M” suffix signify on the 81122 M thrust bearing?
The “M” denotes a precision-machined brass cage, which offers superior wear resistance and structural integrity under heavy impact loads compared to standard steel cages.
-
Can the 81122 M bearing accommodate radial loads during operation?
No, as a strict cylindrical roller thrust bearing, the 81122 M is engineered to support exceptionally high axial loads only and cannot accept any radial forces.
-
What makes the 81122 M ideal for plastic extruder applications?
Extruders demand immense, continuous axial pressure pushing back from the screw, which the high axial rigidity and brass cage of the 81122 M handle perfectly without deformation.
