Heavy-duty industrial cylinder featuring dual adjustable pneumatic cushions for precise end-position deceleration. The steel tube construction provides enhanced rigidity for high moment load applications (up to 12,500 N·m bending moment). Integrated wear-resistant band guides ensure smooth operation under 20,000N maximum thrust. Requires ISO VG32 hydraulic oil mist lubrication for optimal performance.
- Metal stamping press ejection systems
- Injection molding machine clamp mechanisms
- Steel coil handling equipment
- Shipbuilding plate bending machines
- Mining conveyor belt tensioners
Installation requirements:
Maintain horizontal mounting orientation (±3° tolerance). Allow minimum 150mm
clearance at rod end for full stroke operation. Use M20 mounting bolts (grade 8.8
or higher) with 250N·m torque specification.
