About the Airtac SAI100 Standard Air Cylinder SAI100AX45
The AirTAC SAI100X45 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 45mm stroke. It delivers a robust 3927 N of push force at 0.5 MPa, making it well-suited for high-thrust, short-travel operations. The extruded aluminum barrel design omits tie rods, providing a clean exterior that integrates seamlessly into modern machinery.
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 threading and operates without a magnet; if position sensing is required later, the barrel includes dual-side sensor grooves compatible with CMSE or DMSE switches, though a -S magnet model would be necessary.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX45 Is Used
Heavy-Duty Stamping
Provides the 3927 N force needed for short-stroke metal forming and riveting in automated assembly lines.
Product Diverting
Acts as a high-power pusher to redirect heavy pallets or components across conveyor belts.
Industrial Clamping
Secures large workpieces during machining operations using standard TC trunnion or FA flange mounts.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX45 the Right Cylinder?
If your application requires less force, stepping down to an 80mm bore yields 2513 N at 0.5 MPa, while moving up to a 125mm bore provides 6136 N. This 45mm stroke is optimal for compact clamping or pressing tasks where space is restricted. Because the stroke is under 300mm, rod-bearing bending from side loads is minimal, though external guides are still recommended for perfectly square pressing motions.
Being a true ISO 15552 cylinder, it serves as a dimensionally interchangeable drop-in replacement for any standard ISO 15552 profile cylinder with a 100mm bore, 45mm stroke, G1/2 port, and compatible mounting accessories like FA/FB flanges. Note that this standard cylinder relies on air pressure to maintain position; it will drift if pressure is lost. For dead-stop holding without live air, consider the SAIL or BSAI locking variants.
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.
