Axial piston hydraulic motor M7V series

high-speedhigh-pressurewith gear reducer

Overview
The M7V / M7X series are variable/fixed displacement motors of swash plate design that can be used in high pressure and high speed condition. By developing and utilizing the accumulated Kawasaki technologies for swash plate type pump/motor, they provide superior performance in wide range of speed from very low speed to high speed rotation that has been achieved only with bent axis type motors. They can be used with general reduction gears or couplings as the installation dimensions (mounting size, output spline) and thread size follow international standard like ISO or SAE.

Features

• Smooth starting characteristic and stable operation at very low speed
• High speed performance on a par with bent axis type motors
• Compact size contributes to better installation
• High reliability and long life for high pressure specification
• Various control options such as electric or pressure control
