A heavy-duty adjustable stroke cylinder featuring dual-axis position locking mechanism for precise stroke control. The chrome-plated piston rod with multi-lip seal ensures minimal leakage (≤0.3 mm³/s). Includes shock-absorbing end caps with 5-stage cushion adjustment for smooth deceleration at high speeds.

Typical Applications:

• Variable-height positioning in automated assembly lines
• Material handling systems requiring adjustable clamping force
• Press-fit operations with depth control
• Packaging machinery with variable product sizes
• Automotive welding jig positioning

Installation notes:

1. Use locknuts (included) for stroke adjustment - tighten to 12-15 N·m torque
2. Maintain 0.5-1mm clearance between cushion needle valve and end cap during adjustment
3. For vertical installations, add external guide mechanisms when loads exceed 15kg

Maintenance:

• Inspect rod seals every 500,000 cycles in clean environments
• Replace cushion seals after 2 million cycles or if deceleration time increases by >30%
• Use ISO VG32 hydraulic oil if manual relubrication required
