Gear & Compressor Fluids

Gear Oil

CAT dump truckThe demand for increased equipment and vehicle productivity requires more frequent and prolonged high-load operation. The thermal stress this creates in the gear box results in tougher than ever challenges in performance, fuel economy, and durability. New on and off road equipment design changes significantly reduce under vehicle air flow, severely limiting natural ambient cooling.

The same is true for industrial gear boxes, where sump sizes have also decreased. With reduced resonance time in the sump to cool, thermal stress increases. We offer a comprehensive line of gear oils for both general and specific applications, formulated using the highest quality mineral and synthetic base oils, coupled with industry leading robust additive packages to exceed OEM required levels of protection.
