product description
Features:
Mobile machinery and hydraulic components;
Axial piston quantitative motor with inclined shaft structure, suitable for open and closed circuits of hydrostatic transmission;
The output speed of the hydraulic motor is related to the pump flow and motor displacement;
The output torque increases with the pressure difference between the high and low pressure sides and the increase of the displacement;
Choose long-life, high-precision bearings and park seals;
It has the characteristics of compact structure design, light weight, low noise and high efficiency;

Note: 1) The data in the table are theoretical values, without considering the volumetric efficiency and mechanical efficiency; the values are rounded.
The maximum pressure of port A or B is shown in the following table:
| Specification 28～125 | Shaft A, Z | Shaft extension B, P |
Nominal pressure PN | 40Mpa | 35Mpa |
Maximum pressure Pmax | 45Mpa | 40Mpa |
Note: 1. For shaft ends Z and P, if the drive shaft has a strong force, the nominal pressure only allows PN=31.5 Mpa
2. Corresponding to the shaft end Z, displacement from 28 to 56: PN=35Mpa Pmax=40Mpa
3. The pressure of port A and B does not exceed 70MPa
a. Clockwise, A flows to B
b. Counterclockwise, B flows to A
In occasions where smooth operation is required, the minimum speed n min cannot be lower than 50 rpm, and the maximum speed is in accordance with the parameter table.
Precautions:
a. During the trial operation, the pump body must be filled with oil and kept full during work;
b. The motor must be started at low speed and no load until the system is completely deflated;
c. In order to reduce noise, all connecting pipes are recommended to be isolated from the fuel tank with flexible components;
d. The temperature at any point in the oil circuit must not exceed 115°C;
e. The allowable value of case drain pressure is absolute to the motor speed. The short-time allowable absolute pressure peak value P k≦0.6Mpa; the case drain pressure during average continuous operation shall not exceed the absolute pressure 0.3Mpa;
4. Implementation standards of hydraulic motors
