The SI63X145S medium-duty pneumatic cylinder features a space-saving design with 25% shorter length than conventional cylinders. Its dual cushioning system reduces end-impact noise to below 75dB(A) at 0.5MPa. The multi-layered sealing structure maintains <2% leakage rate after 5,000km stroke testing. Compatible with ATOSOL 260-1 lubricant for high humidity environments.
- Carton compression in packaging lines (food-grade compliant)
- Clamping mechanisms in CNC fixture systems
- Actuation for automated welding curtains
- Vertical lifting in automotive assembly (max 180N thrust)
- Plastic injection molding ejection systems
Installation tip:
Maintain ≤0.3mm alignment tolerance during mounting. For vertical installations,
use speed controller (ASC-06) to prevent piston rod free-fall. Clean air supply
(40μm filter) extends service life by 30%.
