About the Airtac SAI100 Standard Air Cylinder SAI100BX70S
The AirTAC SAI100X70-S is a double-acting ISO 15552 profile cylinder offering a robust 3927 N push force at 0.5 MPa and 5497 N at 0.7 MPa. Its 70 mm stroke provides the exact short-travel clamping distance needed for heavy-duty jigs and high-tonnage press tools.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance in washdown or chemically active environments. It also features an integrated magnet (-S) that interacts directly with CMSE and DMSE sensor switches housed in the dual-side barrel grooves.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX70S Is Used
Heavy-Duty Stamping
Provides the 3927 N force required to secure heavy metal blanks inside progressive stamping dies before the press cycles.
Injection Molding Extraction
Utilizes the SUS304 rod and 70 mm stroke to safely push dense plastic parts out of molds without risking corrosion from mold-release sprays.
Automated Press Brakes
Actuates heavy clamping arms and back-gauges on metal forming machinery where high thrust and precise short-stroke positioning are critical.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX70S the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant yields a massive thrust jump, moving from 2513 N up to 3927 N at 0.5 MPa. If your application requires less force and faster cycle times, stepping down to the 80 mm bore is advisable. The PT tapered port threads ensure a deep, metal-to-metal seal that resists pressure spikes.
Because this is a standard double-acting actuator, it will not maintain its position if air pressure is lost or exhausted. For vertical loads that require safety holding during an air failure, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant instead. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard 100 mm bore, 70 mm stroke ISO 15552 interface unit.
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 SAI100 Standard Air Cylinder SAI100BX70S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. If you increase the operating pressure to 0.7 MPa, the push force rises to 5497 N.
Yes. The SAI100X70-S is built to the ISO 15552 dimensional standard, meaning its mounting footprint, port locations, and pin sizes are fully interchangeable with other ISO 15552 profile cylinders of the same bore and stroke.
