The Antiwear series is dual-purpose machine lubricants formulated for both hydraulic and spindle lubrication. The dual-purpose formulation eliminates the need to inventory both hydraulic and spindle oils. The primary benefit of the Antiwear series is the fact that they do not emulsify in water and as a result will reject from coolant faster than lower quality products. Faster rejection means easier removal of tramp oil from the coolant by means of decantation, skimming, coalescing and centrifuging.
