High-torque industrial cylinder designed for heavy-duty linear motion applications. Features dual adjustable pneumatic cushions for smooth deceleration and impact reduction at stroke ends. The chromium-plated piston rod incorporates a multi-layered sealing system (primary seal + wiper + guide band) for enhanced contamination resistance. Requires ISO 8573-1:2010 Class 3-4-3 compressed air quality.
- Metal stamping press ejection systems
- Plastic injection molding machine clamp units
- Automotive welding fixture positioning
- Heavy conveyor gate actuators
- Paper mill roller engagement mechanisms
Installation guidelines:
For vertical mounting, always install rod end downward to prevent condensate accumulation.
Lubricate through air port with ISO VG32 hydraulic oil (2-3 drops/m³ air flow) if using non-lubricated systems.
Allow 50mm clearance behind cushion screws for adjustment.
