The excavator swing motor is the core component responsible for the machine's 360° rotation, converting hydraulic energy into precise mechanical motion. Our cutting-edge swing motor series combines decades of engineering expertise with advanced materials science to deliver unmatched performance in harsh working conditions.
Featuring a patented axial piston design with hardened steel components, our motors achieve 15% higher torque density than industry standards while maintaining 92% volumetric efficiency. The integrated anti-shock valve system minimizes pressure spikes during sudden stops, extending service life by up to 8,000 hours even in continuous mining operations.
