Product Overview
The WHITE OMR X 50 (Part Number: 11185537) is a high-performance hydraulic orbital motor engineered for demanding industrial drive applications. Manufactured to White Hydraulics’ exacting standards, this motor operates on the proven orbital (gerotor) principle, converting hydraulic fluid pressure into reliable rotary mechanical power. The OMR X series is renowned for its compact, robust construction and smooth, low-speed high-torque output, making it an ideal direct-drive solution for continuous-duty industrial machinery. With a nominal displacement of 50 cc/rev, this motor delivers consistent performance across a wide speed range without the need for complex gear reduction.
