Product Overview
The WHITE OMS 250 (Part Number: 151F0505) is a high-performance hydraulic orbital motor engineered by the renowned manufacturer White Hydraulics (now part of the Danfoss Power Solutions portfolio). This motor operates on the proven gerotor/geroller orbital principle, where hydraulic pressure acts on a set of internal gear teeth to generate smooth, high-torque rotary motion. The OMS series is specifically designed as a medium-duty, high-torque motor capable of delivering reliable performance in both open and closed loop hydraulic systems. With a displacement of 250 cc/rev, this model is optimized for applications requiring substantial torque output at moderate speeds, making it a critical component in mobile and industrial machinery drive systems.
