About the Airtac SAI100 Standard Air Cylinder SAI100BX75
The AirTAC SAI100X75 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, making the 75 mm stroke optimal for high-impact pressing and heavy load transfer tasks.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. Although it lacks a standard piston magnet for direct sensor switching, the extruded aluminum barrel retains dual-sided sensor grooves for flexible mounting when upgraded.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX75 Is Used
Heavy-Duty Pressing
Provides 3927 N of thrust at 0.5 MPa for assembling bearings and seating heavy mechanical components securely.
Automotive Handling
Shifts heavy chassis or engine blocks along production lines, utilizing the SUS304 rod to resist harsh shop-floor moisture.
Pallet Indexing
Drives large pallets or multiplex conveyor sections with precise 75 mm strokes in high-throughput packaging facilities.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX75 the Right Cylinder?
Choose this 100 mm bore when 80 mm falls short—it steps up from 2513 N to 3927 N at 0.5 MPa, while a 125 mm bore yields 6136 N if your system needs more power. The 75 mm stroke is compact enough to avoid rod-bearing bending, but always mount with FA/FB flanges to handle the high peak thrust.
Because this is a standard double-acting cylinder, it cannot hold a load if air pressure drops. For suspended loads that require fail-safe braking, select the SAIL variant with an air-released lock or use the BSAI bidirectional clamp-lock series. As a genuine ISO 15552 profile cylinder, it offers a drop-in replacement for any matching ISO 15552 mounting interface.
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 SAI100BX75 FAQ
