Sauer Danfoss 90K055 Hydraulic Motor: High-Torque Drive for Industrial Systems
Engineered for heavy-duty construction and mining equipment, the 90K055 hydraulic motor delivers 55cc displacement with precision NC-series control. This axial piston motor generates 450 Nm peak torque at 420 bar continuous pressure, powering excavator swing drives and conveyor systems. Its hardened steel components withstand abrasive contaminants in quarry operations, while EBA-grade coating resists chemical corrosion.

The motor maintains 94% mechanical efficiency across 3100–4200 RPM, featuring zero-leakage rotary seals for 20,000+ service hours. S1-rated noise suppression ensures <78 dB(A) operation in confined spaces. Compatibility with ISO VG 46-68 fluids and integrated flushing ports extend maintenance intervals. Designed for CAT 320 excavators and Liebherr material handlers.
