Description

STFC series hydraulic motor is made by continuous testing and improvement on the basis of absorbing the advantages of static pressure balance of crankshaft connecting hydraulic rod motor at home and abroad. STFC series hydraulic motor has high shell strength and large bearing capacity of internal dynamic components.

Due to the use of hydrostatic balance, the internal friction is reduced, so the heat generation and related negative effects are reduced. STFC080/100 series hydraulic motors can be widely used in the hydraulic transmission system of plastic machinery, ship deck machinery, mining construction machinery, lifting and transportation equipment, heavy metallurgical machinery, oil and coal mining machinery, machine tools, light industrial equipment, drilling rigs and other machinery, especially in the screw drive of the injection moulding machine, lifting winch, drum drive, all kinds of rotary machinery drive and other transmission machinery.

STFC series hydraulic motor Main Characteristics:

  • The shaft distributor with static pressure balance technology prevents the tilt of the distributor, has good sealing performance and less leakage, and can work continuously under high pressure (the highest pressure can reach 29MPa).
  • The sealing ring adopts special material and structure, which reduces the leakage and improves the volume efficiency.
  • The main transmission parts of the motor adopt special materials and advanced heat treatment technology, which improves the overall service life.
  • Because the plunger, connecting rod and eccentric sleeve is designed as static pressure balance, the friction force between the connecting rod and the eccentric sleeve and the lateral force of the plunger body is reduced, and the contact-specific pressure of the ball hinge pair is reduced, which all reduce the friction loss in the transmission process.
  • Therefore, STFC series hydraulic motors have the characteristics of high mechanical efficiency and high starting torque (the mechanical efficiency is more than 0.90).
  • The shape and installation size of this series motor is basically the same as the original Staffa, and the performance parameters are similar to the original Staffa, so it is an ideal choice to replace the imported Staffa motor.
