Mechanical and electrical design
Back gable and bearing
The back gable and the bearing trunnion housing are constructed of
a webbed heavy casting for extra rigidity. There are three neopreene
seals to protect from filtration of water. The sleeve bearings are
water protected. An intermediate safety outlet provides an
escapement for any possible condensation.
The seals are mounted on a chrome-plated, non-corresive, specially
hardened sleeve bushing that is mounted on the drive 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.
