Extreme Load Capacity at Very Low Speed

ISO VG 1000 viscosity provides the thick protective film required in very slow-speed, very high-torque applications — maintaining hydrodynamic lubrication where lower viscosity grades enter the boundary lubrication regime and suffer accelerated wear.

Worm Gear Efficiency — Up to 3.6% Improvement

The low traction coefficient of the PAO base stock reduces fluid friction in the sliding contact zone of worm gears — the gear type with the highest internal friction losses. Up to 3.6% energy efficiency improvement vs mineral equivalents in worm gearbox testing.

Exceptional Oil Life

RPVOT of 2,500 minutes and TOST of 10,000+ hours — among the best oxidation resistance results available in any industrial gear oil. Critical for filled-for-life gearboxes and remotely located equipment where oil change-out is difficult or impossible without extended shutdown.

Wide Temperature Range

Viscosity index of 184 and pour point of -42°C — exceptional for a VG 1000 grade. Ensures reliable cold-start lubrication in remote or cold-climate applications while maintaining adequate film thickness at elevated operating temperatures without viscosity thinning.

Shear Stability

Virtually no viscosity loss under mechanical shear in heavily loaded gear and high-shear bearing applications — maintaining ISO VG 1000 protection across the full service interval, unlike thickened mineral oils which can shear down and lose viscosity grade.

Rust, Corrosion & Water Resistance

Passes ASTM D665 Procedure B rust test. Excellent demulsibility, foam control and air release performance — essential for worm gearboxes and bearing housings operating in wet or humid environments where water contamination is a risk.

Worm Gearboxes

High-ratio worm reducers in conveyors, packaging lines, hoisting equipment and industrial drives · Filled-for-life worm gearboxes where conventional oil change intervals are impractical · Low-efficiency worm gears where energy savings from synthetic lubrication are commercially significant

Mining & Heavy Industry

Very slow-speed mill pinion and trunnion drives · Large rotary kiln gear drives · Mine winder auxiliary gearboxes · Bucket elevator drives · Heavy crusher feeder gearboxes where ISO VG 1000 is nameplate-specified

Slow-Speed Bearings

Mixer roll bearings and roll neck bearings operating at high temperatures · Heavily loaded plain and rolling contact bearings at very slow speeds · Severe centrifuge bearing applications including marine centrifuges · Large trunnion bearings on rotating drums

Remote & Difficult Access Applications

Remotely located gearboxes where oil change-out requires extended production shutdown · Elevated or inaccessible gearboxes where drain interval extension directly reduces maintenance cost and safety risk · Plastic calenders and other process machinery with high change-out cost
