Standards
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
| Series | factor ko |
| 811 | 1,4 |
| 812 | 0,9 |
| 813 | 0,7 |
| 814 | 0,4 |
| 893 | 0,7 |
| 894 | 0,5 |
Cages
Axial cylindrical roller bearings come with machined brass cages.
Our favourite is the roller guidance version, letter code M. It is
possible to deliver the versions MB and MPB (cage supported on a
disc washer).
Equivalent dynamic load
P = Fa [kN]
Equivalent static load
P0 = Fa [kN]
