Product Introduction

The MRH2-4400 hydraulic motor is a device that converts hydraulic energy into mechanical energy through the principle of hydraulic transmission. Unlike electric motors, hydraulic motors are driven by the flow and pressure of hydraulic fluid (usually oil or water), offering advantages such as high output torque, wide speed range, compact structure, and easy stepless speed regulation. Here are some key features of the MRH2-4400 hydraulic motor:

 

lHigh power density: The MRH2-4400 hydraulic motor provides high power output, suitable for applications requiring high torque and low speed operation. Wide speed range: The hydraulic motor can achieve stepless speed regulation by adjusting the pressure and flow of the hydraulic system and the internal structural parameters of the motor, adapting to different working requirements.

 

lSelf-locking function: The hydraulic motor can self-lock when hydraulic pressure is lost, maintaining its current position, which is very useful for applications requiring precise position control.

 

lCompact structure: The MRH2-4400 hydraulic motor adopts a modular design, resulting in a compact structure that facilitates installation and maintenance.

 

lHigh adaptability: The hydraulic motor can withstand harsh environments such as high temperature, high pressure, and corrosion, and is widely used in engineering machinery, aerospace, shipbuilding, metallurgy, and other fields.


The MRH2-4400 hydraulic motor typically forms a hydraulic system with components such as a hydraulic pump, oil tank, and filter. The motor's operation and speed regulation are achieved by controlling the flow and pressure of the hydraulic oil. When selecting and using the motor, the model and parameters must be determined based on specific working conditions and requirements to ensure it meets application requirements and maintains good performance.

FAQ

FAQs
  • 1.  Is the installation dimension of your MRH2-4400 hydraulic motor the same as the original motor from JP, and do any modifications need to be made during installation?
    Created with Sketch.
    形状 Created with Sketch.
    Our MRH2-4400 hydraulic motor has the same installation dimension as the original motor from JP, and it can be used without any modifications. As long as the model is confirmed to be the same, all the installation dimensions of the motor will be exactly the same as this.
  • 2.  Is the Accessories of your MRH2-4400 hydraulic motor interchangeable and compatible with the original one from the JP?
    Created with Sketch.
    形状 Created with Sketch.
    Our MRH2-4400 hydraulic motor Accessories are different from the original Accessories made in Japan, and they cannot be used and interchanged
  • 3. What is the difference between the maximum working pressure of different types of hydraulic motors?
    Created with Sketch.
    形状 Created with Sketch.
    The maximum working pressure of different types of hydraulic motors is as follows:
    a. Type MRH/MRH2 of Japanese KAYABA(KYB) is 245bar;
    b. Type HMB/HMC of British STAFFA is 275bar;
    c. HMKB/HMJC/HMKC of Japanese KAWASAKI STAFFA is 275bar;
    d. Type MR/MRD Italian CALZONI is 250bar;
    e. Type CA of Swedish HAGGLUNDS is 350bar
