Hydraulic Machinery & Systems

Robust, high-performance hydraulic solutions designed for demanding marine and offshore applications, including low-speed high-torque motors, swash plate axial piston motors, and precision-engineered piston pumps.

Low Speed High Torque Motor

The RM hydraulic motor from Jiangsu Masada-Mitsubishi Hydraulics incorporates complete technology and quality control processes from Mitsubishi Heavy Industries Machinery Systems. Compact and lightweight, it is engineered to enhance core performance, sliding efficiency, and durability, meeting the demands of low-speed, high-torque applications.

Featuring a well-designed radial piston structure, it delivers high output torque across a wide speed range. The motor’s multiple displacement capability allows for variable output by adjusting the cam’s eccentric distance, enabling flexible performance to suit diverse operational needs.

Key Features

Compact design with simplified construction

High efficiency with reduced internal losses for energy savings

Strong starting performance

Two-speed operation: low speed/high torque and high speed/constant torque when paired with a special service valve (manual or variable)

Supports continuous operation at 24.5 MPa for high reliability

High-pressure oil seal allows drain line pressure up to 1.0 MPa

Robust shaft design supports high load capacity
