About the Airtac SAI63 Standard Cylinder SAI63AX160S
The AirTAC SAI63X160-S is a double-acting ISO 15552 profile cylinder engineered for standardized automation. Delivering a robust 1559 N push force at 0.5 MPa, this 63 mm bore unit is tailored for mid-tier actuation tasks. The 160 mm stroke provides ample travel for indexing, clamping, and lifting modules.
Equipped with a SUS420J2 stainless steel rod, this model offers superior corrosion resistance compared to standard carbon steel. The integrated magnet (-S) enables seamless position sensing using CMSE or DMSE switches housed within the dual-side sensor grooves of the extruded aluminum barrel.

Where the Airtac SAI63 Standard Cylinder SAI63AX160S Is Used
Automated Clamping
Provides consistent 1559 N clamping force for machining fixtures and automated assembly lines.
Product Diverting
Actuates sorting gates and diverter arms on packaging conveyors with smooth, adjustable air cushions.
Material Lifting
Lifts intermediate workpieces or pallets in process machinery, utilizing the integrated magnet for end-position verification.
Is the Airtac SAI63 Standard Cylinder SAI63AX160S the Right Cylinder?
If your application requires less force, stepping down to the 50 mm bore yields 982 N at 0.5 MPa, while moving up to the 80 mm bore provides 2513 N for heavier loads. This 160 mm stroke falls well within standard limits, keeping the assembly compact.
Because air pressure only decelerates the piston near stroke end, this cylinder will drift if supply pressure is lost. For vertical loads requiring fail-safe holding, consider the SAIL variant with an air-released lock. This genuine AirTAC component ensures reliable ISO 15552 dimensional interchangeability.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
