High-precision adjustable stroke cylinder featuring dual-position mechanical stops for mid-stroke positioning. The external cushion adjustment screws allow precise control of end-position deceleration, minimizing impact noise. Anti-rotation rod design ensures stable linear motion, with corrosion-resistant construction suitable for humid environments.

Typical Applications:

• Precision clamping fixtures in CNC machining centers
• Variable position stops in automated assembly lines
• Packaging machine pusher mechanisms
• Textile machinery thread tension control
• Semiconductor handling equipment positioners

Operation tip: Adjust cushion screws in 1/4-turn increments while observing motion. For heavy loads (>15kg), reduce operating pressure to ≤0.6 MPa. Use locknuts (not included) to secure stroke adjustment collars after positioning.

Mounting Guidelines:

• Allow 5mm clearance around adjustment collars for tool access
• Align cylinder axis within ±0.5° of load movement path
• Install speed controllers for optimal cushion performance
• Maximum side load: 30N at rod end
