The SAI80X270S is a heavy-duty ISO 15552 compliant cylinder featuring corrosion-resistant construction and precision honed tubing. Its double-acting design with auto-switch grooves (T-slot) enables position feedback integration. The wear-resistant rod guide and multi-lip seals ensure ≤0.5mm/s leak rates at 0.5MPa. Requires 40μm filtered air and ISO VG32 lubricant for optimal performance.
- Industrial automation press systems
- Plastic injection molding ejectors
- Automotive welding fixture clamping
- Material handling conveyor gates
- Packaging machine stopper mechanisms
Installation note:
Allow ≥10mm alignment tolerance during mounting. For vertical installations,
use rod-down orientation with 0.1-0.3MPa residual pressure to prevent seal wear.
Lubricate through air supply (oil mist 1-2 drops/m³).
