Abstract
A system that extends the life of bearings that support a primary payload and operate in oscillatory mode. The system integrates the primary payload, a reaction mass and the bearings into a single support structure so that constant hydrodynamic lubrication of the bearings is achieved even during stopping and reversal of the primary payload. This is accomplished by allowing the bearings to rotate continuously in one direction while the primary payload is oscillated. Torque compensation may be provided by applying an opposite torque to the reaction mass to minimize the torque disturbance experienced by the support structure.
