About the Airtac SAI63 Standard Cylinder SAI63AX130S
The AirTAC SAI63X130-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa and 1402 N of pull force. Its 130 mm stroke strikes an excellent balance for mid-length travel tasks, while the adjustable air cushions at both ends ensure smooth piston deceleration.
Configured with an -S magnet, this model is fully compatible with CMSE and DMSE reed switches for precise position sensing. It features a SUS420J2 stainless steel piston rod for superior corrosion resistance and utilizes PT tapered port threads for a robust pneumatic connection.

Where the Airtac SAI63 Standard Cylinder SAI63AX130S Is Used
Automated Clamping
Provides 1559 N of thrust at 0.5 MPa for securely holding metal workpieces during machining or welding operations.
Product Diverting
Drives mid-sized diverters and sorting gates on packaging lines with reliable 130 mm travel and integrated position sensing.
Pallet Stops
Acts as a robust stopper mechanism for medium-weight pallets on roller conveyors, utilizing adjustable cushions to absorb impact.
Is the Airtac SAI63 Standard Cylinder SAI63AX130S the Right Cylinder?
Selecting this 63 mm bore over the smaller 50 mm option upgrades your 0.5 MPa thrust from 982 N to 1559 N, making it ideal for heavier material handling. If your application requires less force, stepping down to the 40 mm bore yields 628 N. Because the 130 mm stroke is relatively short, side-load stress on the rod bearing is minimal compared to longer travel units.
This cylinder uses a G3/8 port and M16x1.5 rod thread. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard cylinder matching these mounting interface dimensions. Note that the standard SAI does not hold loads pneumatically; if your process drops air pressure, the piston will drift. For fail-safe load holding, specify the SAIL variant or an external rod lock.
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.
Airtac SAI63 Standard Cylinder SAI63AX130S FAQ
