Performance Lubricants

When it comes to protecting heavily loaded open gears, Whitmore’s Envirolube® has been recognized by OEMs and end-users alike as that product.

This open gear lubricant offers the maximum protection from wear. The combination of a dense protective film, plus special chemical extreme pressure additives ensures smooth operation, even on gears that operate under the most severe load conditions.

By using Envirolube on heavily loaded gears, existing wear damage such as pitting or spalling is smoothed, restoring a smooth operating surface. This process is called “Planishing”.

Envirolube creates an effective layer of chemical and physical protection that prevents scuffing and pitting. The opposing asperities experience extreme load, but are prevented from welding to each other. The pressure causes the high points to yield, and they are pushed down into the “valleys”. The result is radical improvement in surface smoothness to both new and previously damaged gears. A separate running-in lubricant is unnecessary.
