Abstract
A sealed bearing system has a pressure-retaining seal separating two lubricating chambers, one pressure balanced to the outside and the other pressure balanced to the inside. The pressure retaining seal may be a non pumping seal. Radial bearings may be mounted near either axial side of the seal to prevent deflection. The pressure-retaining seal may include a flange and the flange may be axially compressed between a seal carrier and a portion of an outer tubular to fix the seal to the outer tubular. The seal and seal carrier may be installed using a mandrel on which they are temporarily positioned in order to insert and install them into the outer tubular.
