Servo Hydraulic Cylinders HENGLI SERVO

Hengli servo hydraulic cylinders in three sealing designs: HLSL — low-friction seals and a magnetostrictive position sensor, up to 15 Hz, stroke up to 5,000 mm; HLSG — throttle gap seal with pressure-free contact seals, up to 400 Hz; HLSS — double-rod with hydrostatic rod support, up to 400 Hz and up to 1,568 kN at 32 MPa. Working pressure for all series is up to 32 MPa, speed up to 4 m/s. Hengli also supplies complete servo-hydraulic systems: power unit, servo valves, controller, sensors and software for multi-channel test rigs.
