High-precision rotary clamping cylinder combining linear motion with 90° rotation, featuring hardened stainless steel guide rod and anodized aluminum body. The dual-piston design ensures smooth rotation and precise positioning, with integrated shock absorption for high-cycle applications (up to 1,500,000 cycles). Includes anti-rotation keyway and dust-resistant seals.
- Automated fixture positioning in CNC machining centers
- Workpiece clamping in robotic welding systems
- Pallet locking in assembly line transfer units
- Tool changing mechanisms in precision equipment
- Orientation adjustment in packaging machinery
Installation note:
Maintain parallel alignment between cylinder axis and load direction.
Use locking compound on mounting screws (Torque ≤3.5N·m).
Requires 5μm filtered air with 1-10 cSt viscosity oil mist lubrication for optimal performance.
- Max rotation speed: 60 RPM
- Allowable moment: 0.8N·m (static), 0.3N·m (dynamic)
- Breakaway pressure: ≥0.15MPa
- Air consumption: 27.5cm³/stroke (at 0.5MPa)
