OMS315 / BMSY315 Cycloidal Hydraulic Motor is a low-speed high-torque (LSHT) hydraulic motor with a displacement of 315cc. Adopting an advanced disc-type flow distribution structure and Geroler gerotor gear set design, it achieves excellent power density and energy efficiency within a compact size. This model is equipped with a 32mm straight shaft with flat key, G1/2 BSPP lateral oil port and a built-in speed sensor, making it an ideal choice for various construction machinery, agricultural equipment and industrial drive systems.

This product can perfectly replace the Danfoss OMS 315 series (original part number 151F0506) and equivalent displacement models of international brands including Eaton, White and M+S. Its installation dimensions are completely consistent with the original products, enabling plug-and-play seamless replacement without any modification. The golden 315cc displacement strikes an ideal balance between torque output and speed range. The built-in speed sensor can monitor motor speed in real time, realizing accurate closed-loop control and intelligent equipment management.

1. Disc Valve Distribution Technology - Industry-leading Energy Efficiency
The BMSY/OMS series adopts an advanced end-face valve distribution structure, which is different from the traditional spool valve distribution technology:

• High distribution accuracy: The valve distribution mechanism is integrally formed with the output shaft, delivering higher oil distribution accuracy and high volumetric efficiency.
• Automatic wear compensation: The valve plate can automatically compensate for wear during operation, maintaining high volumetric efficiency over the long term and ensuring stable rotational speed and load speed characteristics.
• High operating pressure: The advanced valve distribution structure enables the motor to drive larger loads and supports a higher operating pressure rating.
• Excellent efficiency retention: Maintains high efficiency even under high-pressure operating conditions with long-term stable performance.

2. Geroler Gear Set (Pinned Gerotor Stator-Rotor) - High Efficiency & Durability
It adopts a roller-type cycloidal gear set design, which has remarkable advantages over traditional Gerotor gear sets:

• Rolling friction design: The pinned stator-rotor replaces sliding friction, significantly improving mechanical efficiency and reducing energy loss.
• Low starting pressure: Features low starting pressure, with starting torque exceeding 90% of theoretical torque, easily overcoming heavy-load starting resistance.
• Long service life: The pinned stator-rotor and optimized spline parameter design achieve high mechanical efficiency and extended service life.
• Low-noise operation: Optimized gear design ensures smooth operation and lower noise levels.
