Product Overview
The WHITE OMS 315 (Part Number: 151F0506) is a high-torque, low-speed hydraulic orbital motor engineered by White Hydraulics (now part of the Danfoss Power Solutions portfolio). This motor operates on the proven gerotor/gerolor orbital principle, where pressurized hydraulic fluid drives an internal gear set to produce smooth, high-torque rotation at low speeds. The OMS series is specifically designed for heavy-duty industrial and mobile applications requiring reliable starting torque, excellent volumetric efficiency, and the ability to withstand high radial and axial shaft loads. With a displacement of 315 cc/rev, this model delivers substantial torque output suitable for direct-drive and heavy-load positioning tasks in demanding hydraulic circuits.
