Bearing temperatures are all within limits specified by API-610. Testing has shown exceptional performance with bearings temperatures only 50ºF higher than ambient air temperatures. Thrust pots are mounted in driver supports, which contains cowlings welded directly to the support inner walls. The cowling forces the air to travel over the fins of the thrust pot housing thereby maximizing the heat transfer between the housing and air.
