High-force industrial cylinder engineered for heavy-duty linear motion applications. Features corrosion-resistant hard anodized inner barrel and dual anti-rotation guides for precise axial alignment. The 5-stage chromium-plated piston rod withstands side loads up to 15% of maximum thrust. Requires 40μm filtered lubricated air (ISO 8573-1 class 4) with recommended 1-2 drops/m³ oil mist.
- Metal stamping press ejection systems
- Automotive welding fixture clamping
- Plastic injection molding machine core pulling
- Bulk material gate valve actuation
- Paper roll handling equipment
Installation guidelines:
Maintain 0.1mm/m alignment tolerance during mounting. For vertical installations exceeding 45° angle,
use rod-end support brackets (sold separately). Lubricate rod wiper seal weekly in high-cycle (>500,000/yr) operations.
