High-precision adjustable stroke cylinder featuring dual mechanical stoppers for mid-position locking. The through-rod design allows external stroke adjustment while maintaining IP54 protection rating. Integrated cushioning mechanism reduces end-impact noise to below 70dB(A). Includes anti-rotation guide for precise linear motion.

Typical Applications:

• Precision workpiece clamping in CNC fixtures
• Variable height positioning in semiconductor handlers
• Packaging machine product ejection systems
• Automated assembly line tool changers
• Medical device testing equipment actuators

Installation Guidelines: Use locknuts (M6x1.0) with 12N·m torque for mounting. Maintain 0.5mm minimum clearance between stopper plates during adjustment. Lubricate with ISO VG32 hydraulic oil if used below -5℃. Requires 5μm filtered air with 1-2 drops of oil per m³.

Critical Note: Stroke adjustment must be performed in depressurized state. Avoid exceeding 85% of maximum stroke during high-speed (>500mm/s) operations. Regular cleaning of guide slots recommended every 500,000 cycles.
