High-precision industrial cylinder featuring stepless stroke adjustment through its unique mechanical locking mechanism. The double-cushion design minimizes end-impact vibration (≤0.5m/s²) while maintaining positioning accuracy (±0.3mm). Corrosion-resistant anodized surface treatment ensures 5,000km+ service life under ISO 8573-1 air quality standards.
- Variable height positioning in automotive assembly lines
- Pressure-sensitive material handling systems
- Packaging machinery with dynamic stroke requirements
- Plastic injection molding ejector mechanisms
- Semiconductor wafer transfer equipment
Installation note:
Requires minimum 2x bore size clearance for stroke adjustment mechanism.
Lubricate guide shafts with ISO VG32 hydraulic oil monthly. Avoid side-load
forces exceeding 15% of maximum thrust capacity.
