This is too complicated and thats why you are not likely to get any reply
The torque required in any seals is generally too low with respect to the usual torque available on the shaft to be of any significance. It is simple, the
torque → Power loss →heat generated → Seal Failure
So typically the seal frictions and the pressure (in case it is lip seal through the garter springs, or the compression in O rings) , lip materials etc are maintained to have a required torque of fraction of a N-m even at high speeds.
Additionally you have the lip lubrications.
To calculate the torque actually requiredm you have too many variables to consider -
You can always contact the specific bearing manufacturerer qith all your parameters, and he may help you, But is will be too insignificant to be of any use.
