About the Airtac SAI63 Standard Cylinder SAI63AX225S
The AirTAC SAI63X225-S is a double-acting ISO 15552 profile cylinder engineered for drop-in interchangeability with standard global mounting dimensions. Delivering a robust 1559 N push force at 0.5 MPa, this 63 mm bore unit is tailored for a 225 mm non-standard stroke, providing exact actuation length when standard increments fall short.
This configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance over standard carbon steel. It is equipped with a magnetic piston (-S) for seamless position detection using CMSE or DMSE switches, which seat neatly into the dual sensor grooves machined into the extruded aluminum barrel.

Where the Airtac SAI63 Standard Cylinder SAI63AX225S Is Used
Mid-Tonnage Forming
Provides the exact 225 mm reach and 1559 N force needed for medium-duty stamping and press operations.
Diversion Gates
Drives heavy package routing gates on sorting lines where a precise non-standard stroke is required.
Clamping Fixtures
Secures automotive components during machining using the durable SUS420J2 stainless steel rod.
Is the Airtac SAI63 Standard Cylinder SAI63AX225S the Right Cylinder?
Selecting this bore size makes sense when 40 mm cylinders (providing 628 N at 0.5 MPa) lack the necessary thrust, but stepping up to an 80 mm bore (2513 N) would be physically oversized. Because this 225 mm stroke exceeds the catalog's standard 200 mm increment, it is manufactured as a made-to-order unit with nonstandard_stroke set to true.
When integrating this cylinder, note that the adjustable air cushions at both ends decelerate the piston near stroke endpoints but do not lock the load. If your application must hold a position securely after air pressure is removed or exhausted, specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve. Replacement matching requires a 63 mm bore, 225 mm stroke, PT G3/8 port, and your specific mounting accessory (such as LB foot or TC trunnion).
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.
