High-force industrial cylinder engineered for heavy-duty linear motion applications. Features corrosion-resistant anodized construction and precision honed tube for smooth operation. The adjustable air cushion minimizes impact noise while maintaining consistent stopping precision across full stroke lengths. Requires filtered lubricated air (ISO 8573-1:2010 class 4.4.3 recommended).
- Metal stamping press ejection systems
- Automotive assembly line clamping fixtures
- Injection molding machine core pullers
- Bulk material handling gates/diverters
- Paper mill roller positioning mechanisms
Installation note:
Ensure proper alignment of piston rod axis (±0.2° angular misalignment max).
For vertical mounting, install locking nuts on piston rod threads.
Lubricate through air supply (ISO VG32 equivalent) if not using self-lubricated seals.
