About the Airtac SAI100 Standard Air Cylinder SAI100BX140S
The AirTAC SAI100X140-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty handling. It delivers a robust 3927 N push force at 0.5 MPa, making it well-suited for mid-stroke pressing and robust lifting tasks.
This specific configuration includes a -S magnet for direct mounting of CMSE or DMSE sensor switches along the dual side grooves. It is built with a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads to ensure a tight pneumatic seal.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX140S Is Used
Heavy-Duty Pressing
Provides 3927 N of push force at 0.5 MPa for securely seating bearings and bushings in automated assembly lines.
Pallet Lifting
Generates ample lifting power for raising heavy industrial pallets or chassis components during manufacturing processes.
Material Diversion
Actuates large diverter arms and sorting gates on high-throughput packaging and logistics conveyor systems.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX140S the Right Cylinder?
If an application requires less thrust, stepping down to the 80 mm bore yields 2513 N at 0.5 MPa, whereas moving up to the 125 mm bore provides 6136 N for heavier loads. For this 140 mm stroke, side-load bending on the rod bearing is minimal, but always verify that the load is axially aligned.
Because this is a standard double-acting cylinder, it cannot hold a load if air pressure drops or the valve is centered; the piston will drift. For position-holding needs without live pressure, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 cylinders, matching the 100 mm bore, 140 mm stroke, G1/2 port, and standard mounting accessories like FA flanges.
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.
