About the Airtac SAI100 Standard Air Cylinder SAI100AX145
The AirTAC SAI100X145 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a robust push force of 3927 N at 0.5 MPa, making it well-suited for high-thrust pressing and clamping tasks within its 145 mm stroke. The extruded aluminum barrel design eliminates tie-rods, providing a clean exterior that resists debris accumulation.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It utilizes PT tapered port threads, and because it lacks the -S magnet option, it operates without integrated position sensing. Adjustable air cushions at both ends absorb kinetic energy to protect end-of-stroke components.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX145 Is Used
Heavy-Duty Stamping
Provides the 3927 N push force required to form, stamp, or mark rigid materials in automated production cells.
Pallet Diverting
Actuates heavy lane guides or diverter arms to route loaded pallets along high-throughput packaging lines.
Industrial Clamping
Secures large workpieces or molds during machining and welding operations, utilizing its rigid 100 mm profile body.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX145 the Right Cylinder?
Selecting this 100 mm bore cylinder is ideal when your application requires substantial force that smaller bores cannot provide, such as upgrading from a 80 mm bore that only offers 2513 N at 0.5 MPa. If your system demands less than 3927 N, stepping down to an 80 mm bore saves valuable space and air consumption. The 145 mm stroke offers a compact extension length for localized tasks.
Because the standard SAI100X145 is double-acting, it relies entirely on continuous air pressure to maintain its rod position. If pneumatic supply is lost, the cylinder will drift and cannot hold a load. For applications requiring true drop prevention or position holding without live pressure, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. This model serves as a direct dimensional drop-in replacement for any ISO 15552 cylinder matching its 100 mm bore, 145 mm stroke, and G1/2 port size.
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 SAI100AX145 FAQ
At a standard operating pressure of 0.5 MPa, the SAI100X145 generates a push force of 3927 N and a pull force of 3681 N. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X145 is dimensionally interchangeable per ISO 15552. As long as your existing setup uses a 100 mm bore, 145 mm stroke, and G1/2 porting, it can serve as a drop-in replacement for other ISO 15552 profile cylinders.
