Boundary dimensions: ISO 15:2011
Series 10, 02, 03
Values: ISO 492:2014 (table 1)
Due to the special surface treatment of the bearings, there may be slight deviations from the standard tolerances. These deviations do not affect mounting or bearing operation.
|Multiples of C5, except for VA237 which is C4 as standard.
Values (table 2) are valid for unmounted bearings under zero measuring load.
||≈ 20 to 30 minutes of arc
The above values apply only when the bearings rotate slowly. The permissible angular misalignment between the inner and outer ring depends on the size and internal design of the bearing, radial internal clearance in operation and the forces and moments acting on the bearing. As a result, only approximate values are listed here. Any misalignment increases bearing noise and reduces bearing service life.
||120 °C (250 °F)
The rings, rolling elements and cages of SKF high temperature bearings undergo the same heat stabilization process as the relevant standard bearing. As a result, for higher operating temperatures, a certain amount of dimensional change is to be expected. For additional information, contact the SKF application engineering service.
