High-force industrial cylinder designed for heavy-duty automation applications. Features precision-machined aluminum barrel with corrosion-resistant treatment and wear-resistant piston seals. The extended stroke design accommodates long-range linear motion requirements while maintaining stability through dual air cushioning. Requires filtered compressed air (40μm particle size max).
- Press machine ejection systems
- Automotive assembly line positioning
- Foundry equipment actuation
- Large-scale material handling gates
- Construction machinery actuators
Installation note:
Ensure proper alignment of mounting surfaces (tolerance ≤0.2mm/m).
Allow minimum 50mm clearance at rod end for full stroke operation.
Lubricator oil feed rate should be 1-2 drops/m³ of air consumption.
