Product Advantages

Hydraulic Motors: High torque output, High power density, Low Internal Leakage, Quiet Operation & Imported Sealing. Equipped with imported seals, it significantly bolsters the sealing effect, preventing hydraulic oil leakage and extending the service life of the motor.
High torque output
The hydraulic motor can provide extremely high starting torque at low speeds, making it particularly suitable for heavy-load or high-resistance scenarios
High power density
Compared with electric motors, hydraulic motors are smaller in size and lighter in weight, yet they can output greater power, making them suitable for space-constrained applications.
Exceptional Internal Leakage Control
The product features minimal internal leakage, effectively reducing hydraulic oil loss. This not only enhances the stability of the system but also optimizes energy utilization.
no data
Low Noise Operation
During operation, it generates minimal noise, creating a quieter working environment. It is particularly suitable for noise - sensitive applications.
Superior Sealing Performance
Equipped with imported seals, it significantly bolsters the sealing effect, preventing hydraulic oil leakage and extending the service life of the motor.
