The T121986 OMV500 cycloidal hydraulic motor is a large-displacement, low-speed and high-torque hydraulic motor. Featuring the original part number T121986, it is a key original replacement component for the travel and conveyor drive systems of mobile crushing and screening equipment manufactured by Powerscreen (a brand under Terex). Designed based on Danfoss (formerly Sauer-Danfoss) OMV series platform, this motor adopts an advanced Geroler roller cycloidal gear set and disc-type flow distribution structure, delivering excellent power density and energy efficiency within a compact size.

This product serves as a core component for the travel drives and conveyor drives of Powerscreen and Terex crushers, screens and stackers. It enables plug-and-play seamless replacement with the original OMV500 motor, ensuring reliable operation of equipment under harsh working conditions such as mining, quarries and recycling applications.

1. High-strength load-bearing design
Tapered roller bearings: Double tapered roller bearings are adopted at the front and rear of the output shaft, with a radial load capacity > 2000 N, meeting the requirements of heavy-duty applications.
L10 bearing life: 20,000 hours, ensuring long-term reliability under continuous rated operating conditions.
Compact structural design: The high-strength cast iron housing maintains a compact size while bearing high loads.

2. High power density - the first choice for heavy-duty applications
1460 N·m continuous torque: The large 500cc displacement provides sufficient torque reserve to meet the most stringent crushing and screening operating conditions.
400 rpm operating speed: Achieves a good balance between torque and speed.
53.5 kW continuous power: Meets the high power requirements of crushing and screening equipment.
Wide operating range: Stable output within the speed range of 10–400 rpm.

3. Extensive system compatibility
Open/closed system compatibility: Suitable for both open and closed hydraulic systems.
High-pressure shaft seal design: Adopts a high-pressure shaft seal structure, which can withstand high oil return pressure without additional oil drain pipes, and supports series or parallel connection of motors.
Adaptability to harsh working conditions: Suitable for severe operating conditions including high pressure, low-viscosity oil and frequent commutation.
IP65 protection rating: Dustproof and water jet resistant, adapting to harsh environments in mines and quarries.
