About the Airtac SAI63 Standard Cylinder SAI63BX240
The AirTAC SAI63X240 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 240mm stroke. It generates 1559 N of push force at 0.5 MPa, making it well-suited for mid-range industrial actuation. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists debris accumulation.
Configured with a SUS304 stainless steel rod (option B), this unit offers superior corrosion resistance for humid or washdown settings. It utilizes PT tapered port threads, and because no magnet is specified, it ships without sensor tracks. For high-temperature environments up to 70 C, the standard TPU seals handle the task, though Viton (H) alternatives are available.

Where the Airtac SAI63 Standard Cylinder SAI63BX240 Is Used
Clamping Mechanisms
Provides 1559 N of clamping force at 0.5 MPa to secure medium-sized metal workpieces during machining operations.
Product Diverting
The 240mm stroke extends fully to push heavy cardboard cartons from a main conveyor line to a secondary packaging lane.
Material Lift Gates
Actuates heavy access doors or lift gates on automated assembly machinery, utilizing the robust 63mm profile barrel.
Is the Airtac SAI63 Standard Cylinder SAI63BX240 the Right Cylinder?
Selecting this 63mm bore over the 50mm option doubles your thrust (982 N to 1559 N at 0.5 MPa) without a massive footprint increase. If your application requires less than 1559 N, stepping down to the 50mm bore saves space and air consumption. This 240mm stroke provides a 480mm total travel distance, which is moderate, but you should still ensure the rod bearing is not subjected to excessive lateral stress.
Because this is a double-acting pneumatic actuator, air pressure is required to hold a position; if pressure is lost, the piston will drift. If your machinery needs static holding without continuous air, consider the SAIL (air-released lock) variant or an external pilot-operated check valve. This model serves as a direct dimensional replacement for any ISO 15552 cylinder with a 63mm bore, 240mm stroke, G3/8 port, and PT thread.
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 SAI63BX240 FAQ
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X240 is dimensionally interchangeable per ISO 15552 standards. You can use it as a direct replacement for other ISO 15552 cylinders with a 63mm bore and 240mm stroke, provided your port and mounting match.
