About the Airtac SAI100 Standard Air Cylinder SAI100BX120S
The AirTAC SAI100X120-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a robust 3927 N push force at 0.5 MPa and 5497 N at 0.7 MPa, making it well-suited for high-thrust pressing and heavy load transfer over its 120 mm stroke. The extruded aluminum barrel design omits tie rods for a clean exterior.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in washdown or chemically exposed environments. The -S suffix indicates an integrated magnet, allowing seamless operation with CMSE and DMSE sensor switches mounted in the dual-side barrel grooves for precise end-of-stroke detection.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX120S Is Used
Heavy-Duty Pressing
Provides 5497 N of thrust at 0.7 MPa for securely seating bearings, bushings, or rivets in automated metalworking and fabrication lines.
Bulk Package Diversion
Generates the necessary force to push heavy pallets or multi-pack cartons off a high-speed conveyor belt into sorting chutes.
Injection Mold Extraction
Features a corrosion-resistant SUS304 rod and dual-side sensor grooves for reliable part ejection from plastic injection molding machines.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX120S the Right Cylinder?
Select this 100 mm bore when a 63 mm bore (providing 1559 N at 0.5 MPa) is insufficient for moving heavy masses, but you want to avoid the larger 125 mm bore (6136 N at 0.5 MPa) to save valuable machine footprint and air volume. The 120 mm stroke offers a moderate extension range ideal for compact pressing or part ejection tasks.
Because this is a double-acting pneumatic actuator, it relies on continuous air pressure to hold position; venting the circuit causes the rod to drift. If your application requires static holding without air pressure, consider the SAIL locking variant or an external pilot-operated check valve. This unit is dimensionally interchangeable per ISO 15552, meaning it serves as a direct drop-in replacement for other ISO 15552 profile cylinders with matching 100 mm bore, 120 mm stroke, G1/2 PT port, and standard mounting accessories like FA/FB flanges.

- ✓ 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 SAI100 Standard Air Cylinder SAI100BX120S FAQ
At 0.5 MPa operating pressure, the SAI100X120-S provides 3927 N of push force and 3681 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 5497 N.
Yes. The SAI100X120-S is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 standard cylinders. You can swap it directly using the existing 100 mm bore mounting interface, G1/2 port, and standard FA/FB or TC accessories.
