The OMV500 cycloidal hydraulic motor is a large-displacement, low-speed and high-torque hydraulic motor with the part number T121986. It serves as a key genuine replacement component for the travel and conveyor drive systems of Powerscreen and Terex mobile crushing and screening equipment.

Designed on the Danfoss (formerly Sauer-Danfoss) OMV series platform, this motor adopts an advanced Geroler roller-type cycloidal gear set and disc-type valve distribution structure, delivering exceptional power density and energy efficiency within a compact size. The 500cc displacement class provides a continuous torque of up to 1460 N·m and a maximum output speed of 400 rpm, enabling sustained high-load operation in mining conditions and meeting the travel speed requirements of equipment on rough terrain.

As a core component for the travel and conveyor drives of Powerscreen and Terex crushers, screens and stackers, this product features standard specifications including a 4-bolt square flange mount, 50mm straight shaft and G1 BSP main ports, allowing plug-and-play seamless replacement with equivalent models from international brands such as Danfoss OMV 500 and BMV 500.

1. Disc Valve Distribution Technology – Industry-Leading Energy Efficiency
The OMV series adopts an advanced disc valve structure, which offers significant advantages over spool valve distribution:

• Minimized hydraulic and mechanical losses: The independently driven hydraulically balanced disc valve structure effectively reduces internal energy consumption
• Sustained high efficiency: Maintains high efficiency even under high-pressure operating conditions, with excellent starting characteristics
• Automatic wear compensation: The valve plate can automatically compensate for wear, maintaining high volumetric efficiency over the long term
• Lowest pressure loss: The OMV series is one of the gerotor motors with the lowest pressure drop in the industry

2. Geroler Gear Set – Rolling Friction Design
Equipped with a roller-type gerotor gear set (Geroler):

• Rolling friction design: Rollers replace sliding friction, boosting mechanical efficiency by 5–8% compared with traditional Gerotor designs
• High starting torque: Starting pressure < 1.5 bar, and starting torque can reach over 90% of the theoretical torque
• Excellent torque retention: Torque loss retention rate < 0.5%, ensuring stable long-term performance
• Low-noise operation: Optimized gear design reduces operating noise
