High-performance industrial cylinder featuring hard-anodized aluminum construction with chrome-plated steel piston rod. Designed for medium-duty applications requiring precise linear motion and durability. Integrated magnetic piston enables position sensing (sensor slots on cylinder body).

Typical Applications:
  • Press machine ejection systems
  • Material handling conveyor gates
  • Automotive assembly clamping devices
  • Packaging line positioning mechanisms
  • Plastic injection molding machine actuators
Installation guidelines: Use Cush-Lock™ mounting brackets for vibration resistance. Adjust cushion screws clockwise to increase damping force. Maintain 0.5–1 mm rod-end play during mounting alignment.
Maintenance: Replace rod wiper seals every 500,000 cycles in normal conditions. Compatible with ISO 8573-1:2010 [3:4:3] class compressed air. Requires monthly lubrication check in continuous operation.
