About the Airtac SAI100 Standard Air Cylinder SAI100X115S
The AirTAC SAI100X115-S is a double-acting ISO 15552 profile cylinder offering 3927N of push force and 3681N of pull force at 0.5 MPa. The 115mm stroke length provides a compact extension distance for medium-throw tasks. As a genuine AirTAC component, it ensures reliable performance.
This variant includes a magnetic piston (-S) for direct compatibility with CMSE and DMSE reed switches. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting. It utilizes a standard carbon steel piston rod and PT tapered port threads to guarantee a leak-free pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100X115S Is Used
Press Fit Operations
Provides the 3927N push force required to seat bearings and bushings into housings without requiring a full-scale hydraulic press.
Product Diversion
The 115mm stroke rapidly actuates diverter arms on packaging lines to sort heavy products at speeds up to 800 mm/s.
Clamp Fixtures
Holds heavy workpieces securely in welding or machining fixtures, using the magnetic piston to confirm clamp status via CMSE sensors.
Is the Airtac SAI100 Standard Air Cylinder SAI100X115S the Right Cylinder?
Select this 100mm bore when a 63mm bore (1559N push at 0.5 MPa) is insufficient, but a 125mm bore (6136N) would be excessive. The 115mm stroke is a non-standard intermediate length, ideal for applications requiring precise travel without the bulk of a 125mm stroke.
Because the standard SAI is double-acting, it relies on continuous air pressure to maintain its position. If your system loses pressure, the load will drift; for fail-safe position holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. This model is dimensionally interchangeable with other ISO 15552 cylinders, matching the 100mm bore, 115mm stroke, G1/2 port, and standard mounting accessories.
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 SAI100X115S FAQ
At a standard 0.5 MPa operating pressure, the SAI100X115-S generates 3927N of push force and 3681N of pull force. It can reach up to 5497N push force at 0.7 MPa.
Yes. The SAI100X115-S shares standardized ISO 15552 mounting dimensions, making it a drop-in replacement for other ISO 15552 profile cylinders with a 100mm bore, 115mm stroke, and G1/2 port.
