Precision-engineered adjustable stroke cylinder featuring dual-position locking mechanism for mid-stroke positioning. The hardened stainless steel piston rod (HRC 35-40) and chromium-plated cylinder tube ensure extended service life in high-cycle applications. Integrated magnetic slot allows for sensor mounting (sensors sold separately).
- Precision press-fit operations in assembly lines
- Variable height positioning in material handling
- Clamping force adjustment in CNC jigs
- Packaging machine stroke customization
- Textile machinery with space-constrained stroke requirements
1. Use locknut (M16×1.5) with 20-25 N·m torque for stroke adjustment
2. Lubricate with ISO VG32 hydraulic oil if operating below 0.3 MPa
3. Maximum side load: 150 N (use guide mechanism if exceeded)
• Minimum operating pressure: 0.05 MPa (vacuum applications require special seals)
• Maximum piston speed: 800 mm/s (cushion adjustment required above 500 mm/s)
• Repeat positioning accuracy: ±0.3 mm (with clean, dry air supply)
