Bedrock AW 46
Anti-Wear Hydraulic Oil
Mid-grade anti-wear hydraulic oil for the mobile and shop hydraulic systems that specify ISO 46
Bedrock AW 46 is an anti-wear hydraulic oil in ISO viscosity grade 46, the middle of the three Bedrock AW grades and the grade that equipment makers most often specify for mobile hydraulics in a warm climate. It serves excavators, loaders, dozers, truck-mounted cranes, dump bodies, liftgates, forklifts and shop power units that run on an ISO 46 anti-wear oil. The anti-wear additive protects the pump where metal parts rub under pressure.
In service, AW 46 holds its film through a full shift of pump cycling and keeps pressure steady in cylinders and motors. It resists oxidation and thickening at operating temperature, separates from water that enters the reservoir, and controls foam so the pump stays primed. Rust and corrosion inhibitors protect steel and yellow-metal parts in the reservoir, valves and lines while the machine sits between jobs, and its resistance to oxidation helps keep varnish off valve spools.
For a mixed fleet, AW 46 is the grade to stock first. It covers the machines whose manual names ISO 46 and, where the maker's chart allows, the ones that run a lighter grade in winter and ISO 46 the rest of the year. Move to Bedrock AW 68 where the manual calls for the heavier grade and to Bedrock AW 32 where it calls for the lighter one. Tractors that take a universal tractor hydraulic and transmission fluid use Bedrock J20C.

Applications
- Excavators, backhoes, wheel loaders, dozers and compactors whose maker specifies an ISO 46 anti-wear oil
- Truck-mounted hydraulics: dump bodies, liftgates, wreckers, knuckleboom cranes and roll-off hoists
- Forklifts, scissor lifts and boom lifts that call for ISO 46
- Shop presses, hydraulic power units and lift tables in repair shops
- Oilfield service units and winch trucks whose manual names an ISO 46 hydraulic oil
- Farm equipment with a separate hydraulic reservoir that specifies an ISO 46 anti-wear oil
- Year-round service along the Gulf Coast where the maker's temperature chart keeps ISO 46 in range
Performance
- Protects vane, gear and piston pumps against wear where metal meets metal under load
- Holds its viscosity through long hours of pump cycling at operating temperature
- Resists oxidation, sludge and varnish so valves and filters keep working as designed
- Separates from water so it can be drained from the reservoir
- Controls foam and releases entrained air to keep the pump from cavitating
- Protects steel and yellow-metal parts against rust and corrosion during work and storage

Frequently asked questions
Which grade do I need if the manual is gone?
Look for the decal by the reservoir or fill cap first; most makers print the grade there. If there is nothing, ask the dealer that sold the machine for the maker's chart, which lists the grade by working temperature. ISO 46 is the grade most mobile equipment calls for in a warm climate, so it is the usual answer, but confirm it before you fill.
How do I switch a machine to Bedrock AW 46?
Drain the reservoir, change the filter and refill with Bedrock AW 46 at the next service; if the old oil is milky or dark, drain it rather than topping it off. Keep one product in the system.
Is AW 46 the same as a tractor hydraulic fluid?
No. AW 46 is an anti-wear oil for dedicated hydraulic systems with their own reservoir. A tractor hydraulic fluid such as Bedrock J20C is a universal fluid for tractors whose hydraulics, transmission and wet brakes share one sump. Use the type the equipment manual names.
Specifications and typical properties are stated on each product's data sheet; follow the equipment maker's service recommendations.
