Product Introduction

HMJC125 two-speed motor has two preset displacements to choose from a wide range to suit specific application requirements. Control and selection is made via directional valve. The displacement can be easily changed while the motor is running. Double-sided main port design, more convenient for hydraulic motor control valve layout.

HMJC125 is a two-speed axial piston hydraulic motor (often referred to as a "two-speed motor"), part of the HMJ series (two-speed variable speed motors). Its core feature is the ability to switch between two speed/torque modes through mechanical shifting, making it widely used in applications requiring switching between "high speed with light load" and "low speed with heavy load."

HMJC125 two-speed motor achieves efficient power switching through mechanical shifting, making it an optimal alternative to "single-speed motor + multi-valve manifold" systems. It is particularly suitable for applications such as crawler machinery and mining transportation that require a clear combination of "low speed, high torque, and high speed with light load."

HMJC125 two-speed hydraulic motor is a high-performance, versatile hydraulic motor featuring a two-speed design, excellent speed regulation, and a wide range of applications. It is an ideal choice for a variety of industrial applications, providing powerful power support for machinery and meeting diverse load requirements.

FAQ

FAQs
  • 1.Is the installation dimension of your HMJC125 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 HMJC125 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.
    HMJC125 hydraulic motor is identical to Japanese-made motors in terms of installation dimensions and interface standards, enabling seamless replacement while offering the combined advantages of lower cost and superior performance. Customers are advised to prioritize the HMJC125 as an upgrade or replacement option.
  • 2.Is the Accessories of your HMJC125 hydraulic motor interchangeable and compatible with the original one from the JP?
    Created with Sketch.
    形状 Created with Sketch.
    The accessories of our HMJC125 hydraulic motor are same as the original from JP.
    HMJC125 hydraulic motor was designed with special attention to compatibility and interchangeability with Japanese-made products. This means that all components, including the housing, rotor, blades, bearings, seals, and oil inlet and outlet ports, are dimensionally identical to their Japanese counterparts.
    Our HMJC125 hydraulic motor not only achieves exacting part-level dimensional consistency, but also achieves the same level of material, process, and hydraulic compatibility as its Japanese counterparts. This in turn offers the advantages of lower maintenance costs, upgradeable performance, and more convenient service.
  • How to quickly determine if there is a fault with the motor or the control valve group?
    Created with Sketch.
    形状 Created with Sketch.
    a、Connect pressure gauges to ports A and B of the motor, if the motor is obviously not powerful enough and the pressure gauge shows that the pressure is not high when lifting the load, it indicates that the pressure relief valve in the control valve is faulty, and the fault of the pressure relief valve needs to be eliminated;
    b、The motor and pipeline have air, and the operation of continuous multiple times of lifting and lowering under no-load condition is required to exhaust the air, and to ensure the smooth and continuous oil supplement circuit at the motor inlet;
    c、Abnormal loud noise or the temperature of the motor housing wall is significantly higher than the pipeline by more than 20℃ and the temperature is still rising, that the motor is seriously damaged and needs to be repaired or replaced。
