No lubrication maintenance — ever

Since packing will be your only maintenance item, the PowerTrain carriage also eliminates cost. There’s never a need for lubrication maintenance because the carriage features self-lubricated bearings; at-assembly, lifetime gear-side lubrication; and low-friction, dry-film lubrication on the hub chamber’s gear set. Also, since there is no need to add lubricant, there’s never a housekeeping issue.

Extended service life, fewer required rebuilds

The PowerTrain carriage offers uncomparable longevity. Extensive testing in the lab and in operating installations worldwide proves it. Even after tens of thousands of cycles under harsh operating conditions, the PowerTrain carriage eliminates the need for periodic lubrication. And, depending on blowing pressure and cycle rate, it extends the mean time between required rebuilds beyond 50,000 operations. Even at 20 cycles per day, that’s potentially more than seven years of trouble-free operation.

Reliable operation, superior warranty coverage

The PowerTrain carriage comes with an unparalleled written warranty, for reliable operation without internal maintenance, for three (3) years or 30,000 operational cycles, whichever occurs first. Other than normal feed tube packing changes or adjustments (which are external to the carriage), the PowerTrain carriage requires no internal maintenance or lubrication during the warranty period.
