Abstract
Rolling element bearings are located between the eccentric drive pin and the slider block of a scroll compressor. The rolling elements reduce static or boundary lubrication friction by an order of magnitude in providing rolling friction. As a result, movement of the orbiting scroll into and out of flank contact is facilitated and scroll separation takes place earlier in the shutdown process.
