High-precision adjustable stroke cylinder featuring micro-positioning capability (±0.5mm repeatability). The dual chrome-plated piston rod and anodized barrel provide corrosion resistance for harsh environments. Integrated shock absorption system allows smooth operation at maximum speed. Requires 5μm filtered dry air with lubrication (ISO 8573-1 class 3-4-3).
- Variable position clamping in CNC machining fixtures
- Packaging line product height adjustment systems
- Automated assembly with programmable stroke control
- Plastic injection molding ejector mechanisms
- Textile machinery tension adjustment units
Operation note:
Always adjust stroke when cylinder is depressurized. For fine adjustments exceeding 50% of base stroke,
reduce operating pressure to 0.3MPa maximum. Lubricate adjustment threads monthly with silicone grease.
- Allow minimum 3mm thermal expansion gap during mounting
- Maximum side load: 15N at full extension
- Alignment tolerance: ±0.2mm perpendicular to motion axis
- Vibration limit: ≤4.9m/s² at 10-60Hz frequency
