Sauer Danfoss 90K075 Hydraulic Motor: 75cc Variable Torque Drive
Engineered for heavy-duty mining conveyors and tunnel boring systems, the 90K075 hydraulic motor delivers 75cc displacement with precision NC-series control. This axial piston motor generates 550 Nm peak torque at 350 bar continuous pressure, powering high-inertia loads in extreme conditions. Hardened steel components withstand silica dust and rock abrasion, while zero-leakage rotary seals ensure 22,000+ service hours in 24/7 operations.

The motor maintains 95% mechanical efficiency across 3100–4200 RPM, with S1-rated noise suppression below 77 dB(A) for underground compliance. Integrated flushing ports enable continuous contaminant expulsion, extending fluid life in ISO VG 68 systems. Compatibility with fire-resistant HFD fluids meets MSHA safety standards for coal mines.

Designed for Sandvik LH621 loaders and Robbins TBM drive systems. Access torque curves and installation manuals: https://www.baolilai-pump.com/.
