Ultra-slim profile cylinder (15% narrower than standard models) with precision-adjustable pneumatic cushioning mechanism. Features wear-resistant rod guide bushings and dual anti-rotation pins for stable linear motion. The 50mm adjustable cushion range allows fine-tuning of end position deceleration across 15+ preset positions.

Industrial Applications:
  • PCB handling robots requiring precise stop positioning
  • Pharmaceutical blister packaging machines
  • Automated optical inspection (AOI) equipment
  • Semiconductor wafer transfer systems
  • Compact assembly line pusher mechanisms
Operation tip: For optimal cushion performance, make 1/8-turn incremental adjustments while monitoring cycle times. Lubricate cushion screws monthly with ISO VG32 hydraulic oil. Avoid over-tightening (max torque 1.2N·m).
Mounting Considerations:
  • Allow 25mm clearance for cushion adjustment access
  • Use flexible couplings for misalignment >0.5°
  • Pre-charge lubricator recommended for >500,000 cycle operations
