Only Manufacturing Grade a Thrust Cylindrical Roller Bearing (81107/81108/81109/81110/81111/81112/81113/81114)

Thrust Cylindrical Roller BearingStandardsAxial cylindrical roller bearings according to DIN 722 (series 811 and 812) The versions 813, 814, 874, 893, and 894 are not standardied.TolerancesRunning, 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:  Series factor ko 811 1,4 812 0,9 813 0,7 814 0,4 893 0,7 894 0,5 CagesAxial 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 loadP = Fa [kN]Equivalent static load
