Consideration for outer ring rotation

In applications where the outer ring rotates, the speed factor A is calculated differently. In this case, use the bearing outside diameter D instead of dm. The use of an effective seal is a prerequisite to avoid grease leakage.

In applications where there are high outer ring speeds (i.e. > 40% of the reference speed listed in the product tables), greases with a reduced oil bleeding tendency should be selected.

For spherical roller thrust bearings with a rotating housing washer, oil lubrication is recommended.
