1.3 Main Housing Assembly
The main housing assembly contains a main housing, motor cover, extension rod
bearing, and associated seals. See Figure 1-3. The main housing assembly is the
primary structural system component and supports all the bearings, motor control
electronics, motor cover, and mountings, which forms the explosion-proof
containment.
In order to provide main bearing thermal dimensional stability, the housing is fitted
with a stainless steel liner. The liner is permanently installed into the aluminum
main housing. A retaining ring is included for redundant retention.
The main housing contains rigid mechanical stops to prevent extension rod
travel beyond the design specification.
