About the Airtac SAI63 Standard Cylinder SAI63AX230
The AirTAC SAI63X230 is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 1559 N and a pull force of 1402 N at 0.5 MPa. Featuring a 63 mm bore and a 230 mm stroke, this tie-rod-less extruded aluminum barrel design ensures standardized mounting dimensions for straightforward equipment integration.
Configured with a SUS420J2 stainless steel rod for enhanced corrosion resistance, this unit utilizes PT tapered port threads. It operates at speeds between 30-800 mm/s. For applications requiring position detection, the barrel features dual sensor grooves compatible with CMSE or DMSE switches when a magnet is specified.

Where the Airtac SAI63 Standard Cylinder SAI63AX230 Is Used
Automated Clamping
Provides reliable 1559 N clamping force at 0.5 MPa for securing mid-weight machined components during automated milling or drilling processes.
Material Diversion
The 230 mm stroke offers the precise extension needed to actuate diverter gates on packaging lines, handling products smoothly at operating speeds up to 800 mm/s.
Press Ejection
Ideal for ejecting formed parts from light-duty pneumatic presses, utilizing the 1402 N pull force to retract the tooling efficiently.
Is the Airtac SAI63 Standard Cylinder SAI63AX230 the Right Cylinder?
Selecting this 63 mm bore over the smaller 50 mm variant steps the 0.5 MPa push force up from 982 N to 1559 N, while stepping down from the 80 mm bore reduces the footprint without sacrificing substantial thrust. The 230 mm stroke provides ample extension for medium-travel tasks. Because the stroke exceeds 300 mm, side-load management becomes critical; use external guides or a guided cylinder to prevent rod-bearing bending under lateral stress.
This SAI profile cylinder serves as a dimensionally interchangeable drop-in replacement per ISO 15552. To match this exact configuration, specify the 63 mm bore, 230 mm stroke, PT G3/8 port, and your required mounting accessory such as an LB foot or TC trunnion. Note that a standard SAI does not hold its load upon air pressure loss; for dead-load holding, specify the SAIL lock or BSAI clamp-lock variant.
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 SAI63AX230 FAQ
