The revolutionary rodless design results in an installed length only half that of a traditional cylinder for the same stroke, saving substantial space. Since the piston is entirely sealed within the barrel, hydraulic fluid is completely isolated from the external environment, achieving true zero external leakage and high cleanliness.The external carriage and internal piston are coupled via high-performance rare-earth magnets(e.g.,Neodymium),providing large and stable force transmission.They are often integrated with high-precision linear guides and sensor slots,allowing direct use as a precision motion platform.
The working pressure is typically optimized for its applications,ranging from 0.1-10 MPa.Bore sizes are relatively small,commonly ranging from 20mm to 63mm.Strokes can be made much longer than traditional cylinders(up to several meters)as needed.Coupling force is a core parameter and must be precisely calculated based on load and acceleration.Carriage load capacity,repeat positioning accuracy(achievable up to±0.01mm),and maximum operating speed are key performance indicators.Stainless steel body options are available for clean environments.
Primarily used in fields with stringent requirements for space,cleanliness,and precision.In semiconductor and electronics manufacturing,they drive linear motion for wafer handling,dispensing,and inspection platforms.In pharmaceuticals and food processing,they operate valves and perform material handling in sterile environments.In solar panel production lines,they enable precise alignment and lamination.On high-end printing machinery and robot 7th axes,they provide compact and reliable linear motion solutions.
