About the Airtac SAI63 Standard Cylinder SAI63BX30S
The AirTAC SAI63X30-S is a double-acting ISO 15552 profile cylinder engineered for compact, high-force actuation. Operating at 0.5 MPa, it generates 1559 N of push force and 1402 N of pull force, making it highly effective for short-distance clamping and heavy positioning tasks within a tight footprint.
This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a built-in magnet (-S) for seamless integration with CMSE or DMSE sensor switches along the dual barrel grooves. Fluid ports utilize a PT tapered thread standard, ensuring robust pneumatic sealing in demanding industrial environments.

Where the Airtac SAI63 Standard Cylinder SAI63BX30S Is Used
Heavy-Duty Clamping
Provides 1559 N of secure clamping force at 0.5 MPa for holding heavy metal components during machining or welding operations.
Short-Stroke Ejection
Ideal for punching out finished parts from molds or fixtures where a rapid, high-force 30 mm ejection stroke is required.
Product Pressing
Executes precise pressing and riveting tasks for small assemblies, utilizing the robust 63 mm bore to generate immediate downward force.
Is the Airtac SAI63 Standard Cylinder SAI63BX30S the Right Cylinder?
Select this 63 mm bore, 30 mm stroke model when an application demands substantial force in a very short travel distance. If your mechanism requires slightly less clamping pressure, stepping down to a 50 mm bore yields 982 N of push force at 0.5 MPa. Because the standard SAI lacks a physical lock, it cannot hold a load if air pressure is lost; for safety-critical holding, consider the SAIL variant with an air-released lock.
As a dimensionally interchangeable ISO 15552 cylinder, this unit serves as a direct replacement for other standard profile cylinders sharing the same 63 mm bore, 30 mm stroke, PT port, and mounting accessory dimensions. An -S magnet is included for position sensing.
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.
