About the Airtac SAI100 Standard Air Cylinder SAI100X250
The AirTAC SAI100X250 is a double-acting ISO 15552 profile cylinder offering a robust 3927 N push force at 0.5 MPa and 5497 N at 0.7 MPa. Its extruded aluminum barrel eliminates tie-rods while maintaining strict dimensional interchangeability with other ISO 15552 actuators. The 250 mm stroke is well-suited for heavy material handling and high-thrust automation sequences.
Beyond the standard thrust metrics, this configuration features a carbon steel piston rod for structural durability under high axial loads. The barrel includes integrated sensor grooves on both sides, allowing direct mounting of CMSE or DMSE switches if a magnet (-S) is specified later. For environments exceeding standard temperatures, the seal stack can be upgraded to Viton (H) or NBR (N) instead of the standard TPU.

Where the Airtac SAI100 Standard Air Cylinder SAI100X250 Is Used
Heavy Stamping
Provides the high axial thrust needed for pressing bearings or forming metal components in automated manufacturing cells.
Pallet Diversion
Actuates heavy-duty diverter arms to route loaded pallets across conveyor lines without hesitation.
Clamp Fixtures
Secures large workpieces firmly within machining centers, utilizing the full 5497 N force at 0.7 MPa.
Is the Airtac SAI100 Standard Air Cylinder SAI100X250 the Right Cylinder?
Selecting this 100 mm bore makes sense when a 80 mm bore (providing 2513 N at 0.5 MPa) lacks the necessary power, but a 125 mm unit would be physically oversized. At a 250 mm stroke, the extended carbon steel rod is susceptible to bending if subjected to lateral loads; utilizing an external guide rail or a guided cylinder carriage is strongly recommended to prevent premature rod-bearing wear.
Because this is a double-acting pneumatic actuator, it relies on continuous air pressure to hold position. If power or air is lost, the piston will drift. For gravity-loaded vertical setups that require fail-safe holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. Ensure your setup matches the G1/2 port, M20x1.5 rod thread, and PT thread type for a seamless ISO 15552 drop-in replacement.
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 SAI100X250 FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. If you increase the operating pressure to 0.7 MPa, the push force rises to 5497 N.
Yes. The SAI100X250 is a true ISO 15552 profile cylinder, making its mounting dimensions and G1/2 porting fully interchangeable with other ISO 15552 compliant cylinders from various brands.
