About the Airtac SAI63 Standard Cylinder SAI63AX220S
The AirTAC SAI63X220-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 220 mm stroke provides the extended travel needed for pushing, clamping, and lifting tasks in automated lines. The extruded aluminum barrel omits tie-rods, ensuring a sleek profile while maintaining structural rigidity.
This specific configuration includes a magnet for CMSE and DMSE reed switches, enabling precise end-of-stroke detection. It is equipped with a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance, and features PT tapered port threads for a robust, leak-free pneumatic connection.

Where the Airtac SAI63 Standard Cylinder SAI63AX220S Is Used
Automated Clamping
Provides 1559 N of push force at 0.5 MPa, ideal for securing medium-duty workpieces during machining or welding operations.
Product Diverting
The 220 mm stroke offers extended travel to push products across wider conveyor belts or into sorting lanes efficiently.
Pallet Lifting
Leverages the magnetic piston for position feedback, ensuring reliable lifting and lowering of packaged goods in storage systems.
Is the Airtac SAI63 Standard Cylinder SAI63AX220S the Right Cylinder?
When upgrading from a 50 mm bore cylinder, this 63 mm model increases thrust from 982 N to 1559 N at 0.5 MPa. If your application requires less force, stepping down to a 50 mm bore saves space. Since this is a 220 mm stroke, it is below the 300 mm side-load threshold, but you should still ensure axial alignment to prevent premature rod-bearing wear. For applications that must hold a load vertically without continuous air pressure, pair this cylinder with the SAIL air-released lock variant or an external pilot-operated check valve. To match this unit for replacement, specify a 63 mm bore, 220 mm stroke, G3/8 port, PT thread, and the -S magnet option using standard ISO 15552 mounting accessories like FA or LB.
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 SAI63AX220S FAQ
