About the Airtac SAI100 Standard Air Cylinder SAI100BX375
The AirTAC SAI100X375 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N of push force at 0.5 MPa, this 100 mm bore actuator handles substantial payloads with ease. The 375 mm stroke provides ample travel for indexing, clamping, and lifting tasks.
Built with a SUS304 stainless steel piston rod, this variant offers superior corrosion resistance for harsh or washdown environments. It features PT tapered port threads and an extruded aluminum barrel with dual sensor grooves. Note that standard models do not include a magnet; add the -S suffix if position sensing is required.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX375 Is Used
Heavy Machinery Clamping
Generates 5497 N of thrust at 0.7 MPa to secure large steel fabrication components during heavy welding or machining operations.
Pallet Diverting
The 375 mm stroke provides the extended reach needed to push heavy pallets smoothly across high-throughput logistics transfer lines.
Injection Mold Ejection
Leverages the robust 100 mm bore and SUS304 rod to reliably eject dense molded parts, resisting moisture in humid production bays.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX375 the Right Cylinder?
Select this 100 mm bore when 80 mm falls short, jumping from 2513 N to 3927 N at 0.5 MPa. If your application requires less force, stepping down to the 80 mm bore saves space and air consumption. For this 375 mm stroke, long unsupported rods are susceptible to bending under side loads; integrate an external guide rail or use a guided cylinder to prevent premature rod-bearing wear.
This actuator serves as a direct dimensional drop-in replacement for any ISO 15552 cylinder, matching standard mounting footprints like FA flange or TC trunnion. Because it is a standard double-acting cylinder, it will not hold a load if air pressure is lost; integrate an external pilot-operated check valve for fail-safe positioning.
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.
