This was not the case at one North American coal plant. The plant manager and his staff spent too much time maintaining the bearings inside the wind boxes that control the air supply to the combustion process. The bearings still failed regularly despite hours of work each week.

By switching from lubrication-hungry roller-element bearings to GRAPHALLOY self-lubricating bushings, the plant greatly reduced maintenance demands while achieving a more predictable combustion mix. Click here to read more...
