CASTROL™ MOLUB-ALLOY

HIGH PERFORMANCE UNDER EVEN THE HEAVIEST LOADS

Heavy industry places enormous demands on industrial lubricants. High temperatures, high pressures and heavy loads can all combine to break down standard lubricants, leading to expensive equipment failure and unplanned downtime.

From mining to metal production, the bearings, conveyors, chains and draglines you use are subject to massive loads, and optimizing efficiency depends on protecting essential plant.

STANDARD LUBRICANT

Extreme Pressure (EP) / Anti-wear (AW) Lubrication

1

Here, we see two metal surfaces moving relative to each other under full fluid film separation – or hydrodynamic lubrication. Sluble EP/ AW additives float freely in a non-reactive state. The two metal surfaces, retain their natural oxide layers.

2

When temperature or load increases, or velocity decreases, asperities come into contact and the natural oxide layer is removed. As bare metal is exposed, the EP additives activate to form a protective film.

3

Under further pressures, EP films can become overloaded and the additives
are used up. Without them, the contacting asperities weld together – and metal is removed as the bonds break, causing scuffing.
