Our miniature hydraulic rotary actuator measures ≤50 mm in diameter yet delivers torque up to 500 N·m, ideal for medical devices and precision instruments. The vane design uses a composite vane (PTFE + carbon fiber) for low friction (coefficient ≤0.08), and the housing is made from medical-grade stainless steel (316L) for corrosion resistance. With rotation angles up to 270° and speeds to 300 RPM, it fits in tight spaces like surgical robots and lab automation. A microencoder (resolution 0.1°) can be integrated for position feedback.
