Belesta XPG is a lithium complex high temperature grease
which provides outstanding load-carrying capability together
with superior resistance to oxidation and water wash-out.
Belesta XPG is unlike conventional greases in that its polar
attraction to a metal surface ensures that when it is applied it
stays put. As a result, daily greasing is a thing of the past,
and the high load carrying capability and temperature resistance
of the material ensure that effective lubrication is provided,
even in the harshest of environments.
If any of the following apply to your organisation, Belesta
XPG could provide the answer:
Features
- A desire to reduce maintenance costs by extending
greasing intervals
- Rotating equipment with noisy or worn bearings
- Grease failure or loss, on equipment operating at high
temperature
- Wear in equipment operating under high loads or in
aggressive environments

Application Example - Bibby Coupling
Lubrication problems leading to wear on the coupling units of pumps
which run 24 hours per day on steelmaking vessels. Due to high
temperature, the grease either breaks down and is dissipated through
the coupling, or congeals into a hard mass.
As part of a pump replacement exercise a new grid spring was fitted
and the unit packed with Belesta XPG. On recent strip down, the
maintenance engineers were surprised to find the grease in pristine
condition and no signs of wear to the grid spring.
As a result the customer has standardised on the use of Belesta XPG in all future applications of this nature.
