Tianjin Uranus produces rotary cylinders that convert hydraulic energy into rotational motion, featuring vane or gear designs for diverse applications. Vane-type cylinders use precision-machined rotor vanes (clearance ≤0.02 mm) for smooth rotation, while gear-type models leverage a rack-pinion mechanism for high torque. Constructed from ductile iron (QT700-2) or stainless steel (316L), these cylinders offer torque outputs from 100 to 50,000 N·m and rotation angles up to 360°. Common uses include valve actuation in chemical plants, rotary tables in manufacturing, and robotic joint movements. Each cylinder undergoes pressure testing (150% of rated pressure) and leakage testing (helium mass spectrometer method).
