High-precision adjustable stroke cylinder featuring twin external adjustment screws for precise end-position calibration. The dual cushioning system minimizes impact noise while allowing speed optimization up to 1.5m/s. Anodized barrel resists chemical corrosion in harsh environments.

Typical Applications:

• Precision workpiece positioning in CNC loading systems
• Variable height adjustment mechanisms for packaging lines
• Clamping force control in plastic injection molding
• Automated door stroke limitation in cleanroom environments
• Agricultural equipment with variable stroke requirements

Installation note: For optimal performance, align adjustment screws perpendicular to motion axis. Lubricate guide shafts with ISO VG32 hydraulic oil if used in vertical orientation. Maximum side load: 15% of dynamic thrust capacity.

Adjustment procedure:

1. Loosen locknut with 10mm wrench
2. Turn adjustment screw clockwise to decrease stroke (max 30mm reduction)
3. Test cycle 3-5 times after adjustment
4. Retighten locknut with 2.5-3.5N·m torque
