Bedrock AW 32
Anti-Wear Hydraulic Oil

Bedrock AW 32 is an anti-wear hydraulic oil in ISO viscosity grade 32, the lightest of the three Bedrock AW grades. Equipment makers specify ISO 32 for pumps that run at higher speed, for systems with close clearances and long lines, and for machines that start and work in cooler conditions. The anti-wear additive protects the pump's wear surfaces, and the lighter body lets the oil reach the pump quickly at start-up.

In service, AW 32 moves through small valves, filters and long hose runs with less resistance than a heavier grade, so controls respond evenly and the pump is fed from the first stroke of a cool morning. The oil resists oxidation and thickening at operating temperature, separates from water that gets into the reservoir so it can be drained, and controls foam so the pump keeps a solid column of oil. Rust and corrosion inhibitors protect steel and yellow-metal parts while the machine sits.

AW 32 sits below AW 46 and AW 68 in the Bedrock hydraulic line. Choose it when the operator's manual or the decal by the reservoir names an ISO 32 grade, or when the maker's temperature chart moves the machine down a grade for cool-season work. Where the manual lists ISO 46 or ISO 68, use those Bedrock grades instead. All three are anti-wear oils of the same type, so a shop can stock the grades its machines call for under one brand.
