Precision-adjustable pneumatic cylinder featuring stepless stroke adjustment through external mechanical stops. The anodized barrel provides corrosion resistance, while the dual cushioning system enables smooth end-of-stroke deceleration. Integrated magnet slot allows for sensor mounting (inductive sensors not included).

Typical Applications:

• Precision positioning in automated assembly lines
• Variable clamping force applications in CNC tooling
• Packaging machinery with adjustable product height requirements
• Automotive fixture systems requiring stroke flexibility
• Material handling equipment with space-constrained installations

Installation note: Ensure proper alignment of guide rods during mounting. Lubricate through port with ISO VG32 hydraulic oil before initial operation. Adjust cushion screws in 1/4-turn increments for optimal deceleration.

Maintenance Requirements:

• Relubricate every 5 million cycles (or 12 months)
• Inspect buffer adjustment mechanism quarterly
• Maximum side load: 35N at full extension
• Air filtration: 5μm minimum with oil mist lubricator
