About the Airtac SAI100 Standard Air Cylinder SAI100X115
The AirTAC SAI100X115 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty handling, delivering a robust 5497 N push force at 0.7 MPa. Its 115 mm stroke is optimal for mid-range clamping and lifting tasks that require substantial thrust in a compact footprint.
This genuine pneumatic actuator features a standard carbon steel piston rod and a G1/2 PT tapered port thread for secure, leak-free pneumatic connections. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE switches if a magnet (-S) is specified later.
As a true ISO 15552 standardized cylinder, it offers a dimensionally interchangeable mounting interface, serving as a drop-in replacement for other ISO 15552 profile cylinders without requiring machine redesign.

Where the Airtac SAI100 Standard Air Cylinder SAI100X115 Is Used
Heavy-Duty Pressing
Provides the high force needed to seat bearings or stamp light-gauge metal components securely in automated assembly lines.
Pallet Diverting
Actuates robust routing gates on heavy-duty material transport conveyors, easily handling substantial product weight.
Industrial Clamping
Holds large workpieces firmly within CNC machining or welding fixtures to prevent movement during processing.
Is the Airtac SAI100 Standard Air Cylinder SAI100X115 the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant significantly boosts thrust, stepping up from 3518 N to 5497 N at 0.7 MPa for heavier payloads. Conversely, if your application only requires 2182 N, stepping down to the 63 mm bore saves valuable machine real estate and compressed air volume.
Because the 115 mm stroke is relatively short, side-load stress on the rod bearing is minimal compared to longer extensions. However, if your mechanism loses supply pressure, the standard SAI cannot hold a suspended load and will drift; for fail-safe vertical positioning, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant instead of relying on the adjustable air cushions, which only decelerate the piston near stroke end.
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 SAI100X115 FAQ
At an operating pressure of 0.7 MPa, this double-acting cylinder provides a push force of 5497 N and a pull force of 3681 N.
Yes. It is a true ISO 15552 profile cylinder, meaning its mounting interface and dimensions are interchangeable with other ISO 15552 cylinders such as those from Festo or SMC, allowing for a direct drop-in replacement.
