A heavy-duty pneumatic cylinder featuring dual-piston cushioning and wear-resistant rod guides. The hard-anodized barrel surface provides 3x better corrosion resistance than standard models. Designed for high-cycle applications with built-in magnetic slot (optional position sensing). Requires ISO VG32 hydraulic oil lubrication for optimal seal performance.
- Automated material handling systems
- Press machine ejection mechanisms
- Plastic injection molding clamp units
- Automotive assembly line positioning
- Packaging machine vertical lifts
Installation protocol:
Align cylinder axis within 0.2mm perpendicular tolerance. Use only counterbored mounting screws (M8x25 minimum) to prevent thread stripping under lateral loads. Lubricate rod with EP2 grease monthly in high-dust environments.
