About the Airtac SAI100 Standard Air Cylinder SAI100BX40S
The AirTAC SAI100X40-S is a double-acting ISO 15552 profile cylinder free of tie-rods, engineered to deliver a robust 3927 N push force at 0.5 MPa. Its short 40 mm stroke makes it highly effective for high-force clamping and pressing operations within compact machinery envelopes.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance. It includes a magnet for CMSE and DMSE sensor switches, which mount directly into the dual extruded barrel grooves. Fluid ports utilize a PT tapered thread, and the standard TPU seals support a wide 30-800 mm/s speed range.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX40S Is Used
Heavy-Duty Stamping
Generates 3927 N of thrust at 0.5 MPa, making it perfect for short-stroke metal forming and riveting tasks.
Part Ejection
The 40 mm stroke provides rapid, forceful ejection of finished parts from machining centers.
Pneumatic Clamping
Ideal for securing heavy workpieces during welding or machining, utilizing its high force output in a compact footprint.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX40S the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant provides a significant thrust upgrade, jumping from 2513 N to 3927 N at 0.5 MPa. If your application requires less force and a smaller footprint, stepping down to the 80 mm bore is advisable. Because this is a short 40 mm stroke, side-load bending is negligible, but always ensure the load is axially aligned to prevent premature rod-bearing wear.
As a true ISO 15552 profile cylinder, it offers a drop-in replacement solution for any standard 100 mm bore, 40 mm stroke ISO 15552 mounting interface. It uses a G1/2 port, pairs with FA/FB flanges or LB foot mounts, and requires the -S magnet for electronic position feedback. Note that the standard double-acting design cannot hold a load if air pressure drops; for fail-safe holding, consider the SAIL or BSAI variants.
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.
