Product Features

Exceptional Low-Speed High Torque and Smooth Start-Stop Control: High-pressure piston-type swing motor delivers immense rotational torque instantly, ensuring smooth cabin rotation even under fully loaded or sloping conditions. Precision internal control valve design provides smooth acceleration and deceleration buffering, preventing cabin shaking when rotation stops.
Heavy-Duty Wear-Resistant Engineering and Extended Service Life: Key friction components manufactured from high-hardness alloy steel with deep-hardening treatment for superior resistance to wear and cavitation. Rugged cast-iron housing absorbs transient system pressure spikes, reducing failure rates during long-term, high-intensity operations.
Advanced Sealing Integrity and Outstanding Hydraulic Efficiency: Equipped with premium genuine rotary-specific skeleton oil seals and high-temperature O-rings to prevent high-pressure internal oil leakage and block dust or moisture intrusion. Ultra-precise tolerances minimize volumetric leakage, ensuring hydraulic energy conversion efficiency over 90%.
