About the Airtac SAI100 Standard Air Cylinder SAI100AX20S
The AirTAC SAI100X20-S is a double-acting ISO 15552 profile cylinder engineered for high-force, short-stroke automation. Operating at 0.5 MPa, it delivers a substantial push force of 3927 N and a pull force of 3681 N, making it ideal for heavy pressing or clamping tasks within confined spaces. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that aligns with international dimensional interchangeability standards.
This specific configuration includes a SUS420J2 stainless steel rod for enhanced corrosion resistance in humid or mildly chemical environments. It is equipped with a PT tapered port thread and features an integrated magnet (-S), allowing seamless mounting of CMSE or DMSE sensor switches directly into the dual-side barrel grooves for precise end-of-stroke detection.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX20S Is Used
Heavy-Duty Stamping
Provides the 3927 N push force needed for short-stroke metal forming, riveting, and stamping operations in tight machinery layouts.
Product Diverting
Acts as a robust diverter arm or heavy-duty gate in material handling lines, where the integrated magnet allows sensors to confirm gate position instantly.
Pallet Clamping
Secures heavy pallets or industrial components during processing, utilizing the SUS420J2 stainless steel rod to withstand harsh warehouse environments.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX20S the Right Cylinder?
Selecting this 100mm bore over the smaller 80mm variant significantly upgrades thrust from 2513 N to 3927 N at 0.5 MPa, which is critical when a process demands higher clamp force without increasing air pressure. Conversely, if 3927 N exceeds your requirement and space is tight, stepping down to an 80mm bore optimizes footprint and air consumption. Because this model has a very short 20mm stroke, side-load stress on the rod bearing is minimal.
As a standard double-acting cylinder, the SAI100X20-S relies on continuous air pressure to hold a load; it will drift or drop if air is exhausted or removed. For applications requiring position holding without live pressure, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. This model mounts via standard ISO 15552 accessories and uses a G1/2 port.

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.
