FAQ
A1: It is suitable for hydraulic oil and medium‑high pressure, medium‑speed hydraulic rotary equipment.
A2: The hydraulic bearing with wear‑resistant bearings ensures smooth rotation and high pressure resistance, ideal for continuous rotary operation.
A3: They drain a small amount of leaked medium to protect bearings and seals, extending the service life of the joint.
A4: Keep the mating surface clean and flat, ensure good coaxiality, and tighten to the standard torque for stable operation.
