Our rotary cylinders with adjustable rotation speed feature an integrated flow control valve that enables stepless speed adjustment from 10-200 RPM. The vane-type design uses a precision-machined rotor (clearance ≤0.03 mm) and double-lip seals to minimize internal leakage, maintaining speed consistency within ±2% under varying loads. A pressure-compensated flow valve automatically adjusts for changes in system pressure, ensuring stable rotation. This flexibility makes them ideal for robotic arm articulation, indexing tables in assembly lines, and valve actuators in process control systems. The cylinder body is constructed from aluminum alloy (6061-T6) for lightweight design, while the shaft undergoes nitriding treatment (depth 0.3 mm, 800 HV) for wear resistance.
