The maximum transmissible torque is 2 times the specified nominal torque.

The theoretical nominal torque applies only for ideal concentricity between the inner and outer ring. In practice, the concentricity is affected by the bearing play and centering errors of the neigh bouring parts.

Then the nominal torques specified in the table apply, whilst taking into consideration the existing run out (T.I.R.).Higher speeds upon request.
