About the Airtac SAI100 Standard Air Cylinder SAI100BX375S
The AirTAC SAI100X375-S is a double-acting ISO 15552 profile cylinder offering 3927 N of push force at 0.5 MPa. Its 375 mm stroke is well-suited for long-travel material handling and heavy automation tasks.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet (-S) for seamless integration with CMSE or DMSE position sensors along the dual barrel grooves. It uses PT tapered ports and adjustable air cushions at both ends to manage impact.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX375S Is Used
Long-Travel Material Handling
Drives heavy pallets or transfer carts over extended distances requiring the full 375 mm stroke and 3927 N of thrust.
Heavy Stamping and Forming
Provides the consistent clamping force needed for metal bending or pressing operations up to 7068 N at 0.9 MPa.
Automated Warehousing
Actuates large lifting gates or heavy-duty diverter arms in distribution centers, using CMSE sensors to confirm stroke endpoints.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX375S the Right Cylinder?
This 100 mm bore generates 3927 N push at 0.5 MPa; if your application requires less force, stepping down to an 80 mm bore provides 2513 N, while a 125 mm bore yields 6136 N. Because the 375 mm stroke creates a long unsupported rod, avoid side-load bending by using an external guide rail or a fully guided cylinder.
For ISO 15552 drop-in replacement, match the 100 mm bore, 375 mm stroke, G1/2 port, and mounting accessories like FA flange or TC trunnion. If the machine loses air pressure, this standard cylinder cannot hold its load; deploy an external rod lock or the SAIL locking variant for fail-safe position holding.
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 SAI100BX375S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI series is dimensionally interchangeable per ISO 15552 standards. You can drop it in to replace other ISO 15552 profile cylinders by matching the 100 mm bore, 375 mm stroke, and G1/2 port size.
