The Thrust Bearing carries the Thrust Loads generated
by the Press. These can be quite high, especially when full Pressing a fibrous
feed material.
Like the Gearbox a 24Hr/day duty is required, and again
the Bearings will last longest if they are operating in a cooler and cleaner environment. Locating
the Thrust Bearing at the Feed End of
the Press and external to the main Frame Body gives it the best working environment.
The temperatures are lower here and there is less Pressure to force contaminants
into the Thrust Housing.
If the Thrust Bearing is separated form the Gearbox Oil
and located between the working
areas of the Press and the Gearbox it provides a buffer zone to protect
the more expensive Gearbox Internals from contamination.
