Heavy-Duty Gear Oil for Mining and Construction Equipment

Product Description

GL-5 85W-140 heavy-duty axle gear oil is formulated for severe-service axles and gear sets operating under high torque, high temperature and heavy shock loads. It is especially suitable for mining trucks, quarry vehicles, heavy-duty construction machinery, older drivetrains and equipment working in hot climates. The high-viscosity grade helps maintain a durable lubricating film in heavily loaded gears and bearings. It supports protection against scoring, wear and pitting where equipment works under slow speed, heavy load and continuous duty.
