Product Overview
The WHITE OMS 315 (Part Number: 151F0548) is a high-torque, low-speed hydraulic orbital motor engineered by the White Drive Products division of Danfoss Power Solutions. Operating on the proven gerotor/geroler orbital displacement principle, this motor converts hydraulic fluid power into reliable rotational mechanical output without the need for gearboxes or speed reduction devices. The OMS series is specifically designed to deliver smooth, high-torque performance at low speeds, making the 315 displacement variant an ideal choice for heavy-duty industrial applications requiring direct-drive capability, high starting torque, and exceptional resistance to shock loads. As a direct-fit replacement for OEM part number 151F0548, it ensures seamless integration into existing hydraulic circuits.
