High-torque industrial cylinder with wear-resistant construction, featuring precision honed aluminum alloy tube and anti-rotation rod design. Optimized for heavy-duty cycling (up to 5 million cycles @0.5MPa) with low-friction seals. Includes magnetic piston for position sensing compatibility. Requires 40μm filtered air with 1-10mg/m³ lubrication (ISO 8573-1).
- Automated assembly line clamping mechanisms
- Plastic injection molding machine ejectors
- Steel mill material handling systems
- Automotive welding fixture positioning
- Packaging machine vertical lift systems
Installation note:
Maintain 0.5mm minimum alignment tolerance between rod end and load.
For vertical mounting, use rod-down orientation to prevent seal wear.
Lubricate through air supply (ISO VG32 equivalent) for first 100km of stroke travel.
