High-load industrial cylinder designed for heavy-duty automation applications. Features corrosion-resistant construction with precision honed inner tube surface (Ra≤0.2μm) for smooth operation. Integrated magnet position sensing slots (ISO 21287 compliant) enable sensor mounting for position feedback. Requires 40μm filtered lubricated air (ISO 8573-1 class 4).
- Automotive production line clamping systems
- Metal stamping press ejection mechanisms
- Injection molding machine core pullers
- Material handling conveyor diverters
- Heavy-duty packaging press systems
Installation note:
Align cylinder axis within ±0.5° of load path. Use flexible couplings for
stroke lengths >500mm. Lubricate through air supply (ISO VG32 pneumatic oil recommended).
Allow 50mm clearance behind rod end for maintenance.
