Rega platter weight tolerances

I've got a P25 with an Isokinetik bearing sleeve with a ruby bearing. On top is a an Isokinetik GT subplatter, and an Isokinentik 25mm Reference platter with a Herbies mat. I use a J.A. Michell clamp and sometimes a TTWeights 480g outer ring.

I'm also running an Origin Live advanced motor kit with the DC100 motor.

Does anyone think that this will be too much weight for the bearing and the sleeve?

Any input would be appreciated!
Thanks very much!
