About the Airtac SAI100 Standard Air Cylinder SAI100AX45S
The AirTAC SAI100X45-S is a double-acting ISO 15552 profile cylinder built for heavy-duty handling. It delivers a push force of 3927 N at 0.5 MPa, making it well-suited for short-stroke clamping and high-thrust pressing tasks. The extruded aluminum barrel design omits tie rods for a clean exterior.
This specific configuration includes a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and a pre-installed magnet (-S). The magnet enables seamless integration with CMSE or DMSE reed switches fitted into the dual sensor grooves along the barrel sides.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX45S Is Used
Heavy-Duty Stamping
Utilizes the 3927 N push force at 0.5 MPa to securely form and stamp metal components in automated presses.
Pallet Diversion
Provides the robust actuation needed to divert heavy pallets along high-throughput material handling conveyors.
Load Clamping
Holds substantial workpieces stationary during CNC machining or packaging operations using the short 45mm stroke.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX45S the Right Cylinder?
Stepping down to the 80mm bore drops the 0.5 MPa push force to 2513 N, whereas moving up to 125mm increases it to 6136 N. Choose this 100mm option when your application demands maximum thrust within a compact footprint. The PT tapered port threads ensure a robust, leak-free pneumatic connection.
For this 45mm stroke, side load is minimal, but always ensure the load is guided to prevent rod-bearing wear. Note that the standard SAI does not hold a load upon air loss; if your workflow requires dead-stop holding 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 direct dimensional drop-in replacement for other ISO 15552 cylinders.

- ✓ 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.
