About the Airtac SAI100 Standard Air Cylinder SAI100BX145S
The AirTAC SAI100X145-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty handling. It provides a robust push force of 3927 N at 0.5 MPa, extending 145 mm to drive substantial payloads. The extruded aluminum barrel omits tie-rods, creating a clean profile that drops directly into standard ISO 15552 mounting interfaces.
This specific configuration includes a SUS304 stainless steel piston rod for superior corrosion resistance in harsh environments. Equipped with a built-in magnet (-S), it seamlessly integrates with CMSE and DMSE sensor switches fitted into the dual side grooves. Fluid ports feature PT tapered G1/2 threading, and adjustable air cushions at both ends absorb impact at stroke extremes.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX145S Is Used
Heavy Stamping
Drives heavy stamping and forming presses where the 3927 N push force at 0.5 MPa is required to shape thick materials.
Pallet Diverting
Actuates large pallet diverters and heavy load stops on conveyor lines, utilizing the 145 mm stroke to clear the transport path.
Injection Molding
Operates heavy clamps and extraction arms on injection molding machines, relying on the SUS304 rod for coolant resistance.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX145S the Right Cylinder?
Select this 100 mm bore when a 80 mm bore falls short, as the 80 mm yields 2513 N at 0.5 MPa, or when stepping down from a 125 mm unit that outputs 6136 N. The 145 mm stroke is optimal for moderate reach without requiring extensive guiding. Because this is a standard double-acting cylinder, it will not maintain position if air pressure drops; for dead-end holding, specify the SAIL lock or BSAI clamp-lock variant. To match this unit for replacement, specify 100 mm bore, 145 mm stroke, G1/2 PT ports, and a magnet (-S).
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 SAI100BX145S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder generates a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X145-S is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders with a 100 mm bore, 145 mm stroke, and G1/2 ports.
