Axial piston hydraulic motor M3 series

low-speedwith gear reducerfixed-displacement

Product Overview
The M3X series are fixed displacement axial piston motors of swash plate design for mobile applications.
The M3B series are variable displacement axial piston motors of swash plate design for winch application.
These motors have a good self-priming capability and high starting efficiency, developed based on our many years of experience and technology obtained in swash plate type pumps and motors.
By combining the reduction gear RG series and M3X / M3B series, they provide to cover up large capacity.

Features

• Superior performance in low speed operation
• Smooth starting characteristic
• Various displacement control options
• Larger capacity is possible with reduction gears RG series
