A heavy-duty ISO cylinder with precision-machined components for industrial automation. Features double-acting operation with magnetic piston for position sensing compatibility. The hard-anodized barrel resists chemical corrosion and mechanical wear, while optimized air cushioning reduces impact noise by 30% compared to basic models. Requires 5-40μm filtered air with ISO VG32 lubrication (optional oil-free operation).
- Automated assembly line material handling
- Plastic injection molding machine ejectors
- Automotive welding fixture positioning
- Paper converting equipment drives
- Food packaging vertical lift systems
Installation note:
Align cylinder axis within 0.2mm angular misalignment tolerance.
For vertical mounting exceeding 45° angle, install a mechanical
lock on the piston rod. Lubricate guide bearings every 500km of
cumulative stroke movement.
