The BMSY 250cc cycloidal hydraulic motor is a high-performance hydraulic motor that adopts advanced end face porting and Geroler® roller stator-rotor technology, with a geometric displacement of 252 cm³/rev (approximately 250cc). This model is specially equipped with a gear output shaft and an integrated valve block, and is designed to be compatible with international brand models such as Yanmar OMS 230 H. The motor features high working pressure, large starting torque, high volumetric efficiency, and a long service life. It is widely used in fields such as agricultural machinery, construction machinery, material handling, and industrial equipment, and is an ideal choice for applications requiring reliable and efficient hydraulic power.

1. Full Compatibility with Yanmar OMS 230 H
1:1 Direct Replacement: Specifically designed to be compatible with international brand models such as Yanmar OMS 230 H, with a high℃of matching in terms of mounting flange, output shaft, and oil port positions, enabling easy replacement.
Wide Interchangeability: It can also replace international brand models of the same specification, such as Danfoss OMS series and M+S MS series.

2. Advanced Geroler® Roller Stator-Rotor Technology
High Starting Torque: Adopting the inserted roller stator-rotor pair (Geroler®) design, it has low starting pressure, providing smooth and reliable operation and high efficiency. It delivers a continuous torque of up to 450 N·m and a peak torque of 690 N·m, ensuring smooth startup under heavy loads.
Excellent Low-Speed Stability: It can output smooth and continuous torque at low speeds, meeting the requirements of precise control.
High Efficiency Retention: Advanced stator-rotor parameter design ensures high efficiency with good retention and smooth operation.

3. End Face Distribution System
Automatic Wear Compensation: The end face port plate structure is adopted, featuring high distribution accuracy. It can automatically compensate after wear, ensuring long-term maintenance of high volumetric efficiency and a long service life.
Pressure Balance Design: The two sealing end faces of the port plate maintain pressure balance, minimizing internal leakage and improving overall efficiency.
Stable Operation: Ensures stable motor speed and smooth load-speed characteristics.

* Continuous pressure :Max. value of operating motor continuously.
* Intermittent pressure :Max. value of operating motor in 6 seconds per minute.
* Peak pressure:Max. value of operating motor in 0.6 second per minute.
