About the Airtac SAI100 Standard Air Cylinder SAI100X135
The AirTAC SAI100X135 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 135mm stroke. It provides a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making it well-suited for heavy-duty actuation tasks. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior that resists contamination.
This specific configuration features a standard carbon steel piston rod and PT (tapered) port threads. For environments requiring high-temperature resistance up to +70 C, the seals can be upgraded from standard TPU to Viton (H). The barrel also includes dual-side sensor grooves ready for CMSE or DMSE switches when a magnet is specified.

Where the Airtac SAI100 Standard Air Cylinder SAI100X135 Is Used
Heavy Pressing Operations
Ideal for applying high clamping or pressing forces, utilizing its 3927 N push capability at 0.5 MPa to seat components firmly.
Large Material Handling
Moves substantial payloads and heavy pallets efficiently on automated lines where a 135mm stroke provides the necessary reach.
Industrial Stopping
Acts as a robust pneumatic stopper or diverter in conveyor systems, handling the impact loads typical of 100mm bore actuators.
Is the Airtac SAI100 Standard Air Cylinder SAI100X135 the Right Cylinder?
If your application requires less force, stepping down to an 80mm bore yields 2513 N of push force at 0.5 MPa, whereas moving up to a 125mm bore provides 6136 N. Since this 135mm stroke is under 300mm, side-load stress on the rod bearing is moderate, but always verify the load is guided if it is not perfectly axial.
Being a true ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders of the same bore. It uses a G1/2 port, an M20x1.5 rod thread, and offers adjustable air cushions at both ends. Remember that the standard SAI does not lock or hold a load if air pressure is lost; for fail-safe holding, consider the SAIL or BSAI variants.
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.
