Oilgear is an American hydraulics company that was founded in Milwaukee, Wisconsin, in 1921. Since the beginning, Oilgear has been renowned for their cutting-edge technology and the outstanding quality of its pumping products, valving, and systems engineering. Oilgear variable-displacement, axial-piston pumps thrive on low viscosity fluids. Unlike the competition, our pumps are not limited by bearing life. Featuring proprietary hard-on-hard technology in which the running surfaces exceed Rockwell 65, Oilgear pumps are some of the most rugged, longest lasting variable-displacement pumps on the market.
