Rear gable and bearing
The rear gable and the bearing trunnion housing are constructed of a
webbed heavy casting for extra rigidity. There are two neoprene seals to
protect from filtration of water. The sleeve bearings are water protected. An
intermediate safety outlet provides an escapement for any possible conden-
sation.
The seals are mounted on a stainless steel sleeve bushing that is mounted
on the drum shaft to prevent wear of the seals and shaft. The main bearing
is fitted machine-tight into the bearing trunnion housing. A C-clamp is placed
on the shaft to prevent the cylinder from moving in and out.
The extension of the bearing trunnion housing supports the rear bearing
holding the shaft. The bearings are permanently lubricated and need no
maintenance.
