About the Airtac SAI100 Standard Air Cylinder SAI100X185S
The AirTAC SAI100X185-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 5497 N of push force at 0.7 MPa, this 100mm bore unit is built to handle substantial loads across its 185mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies mounting and sensor placement.
This specific configuration includes a magnetic piston (-S) for seamless integration with CMSE or DMSE reed switches, fitting directly into the dual sensor grooves machined into the barrel. The piston rod is constructed from durable carbon steel, and the standard PT tapered port threads guarantee a secure, leak-free pneumatic connection in demanding industrial environments.

Where the Airtac SAI100 Standard Air Cylinder SAI100X185S Is Used
Heavy-Duty Stamping
Provides the necessary 5497 N of push force at 0.7 MPa to drive stamping and forming presses, ensuring consistent part production.
Pallet Diverting
Actuates heavy pallet stops and diverters on high-throughput packaging lines, using the magnetic piston for end-of-stroke position confirmation.
Plastic Injection Molding
Operates large mold ejection mechanisms where a 185mm stroke and robust 100mm bore are required to safely extract finished parts.
Is the Airtac SAI100 Standard Air Cylinder SAI100X185S the Right Cylinder?
Selecting this 100mm bore cylinder makes sense when your application requires significant thrust that smaller bores cannot provide, such as stepping up from an 80mm model which yields 3518 N at 0.7 MPa. If your system demands less than 4000 N, dropping to an 80mm bore can save space and air consumption. At 185mm of travel, the rod bearing handles the load effectively, but always ensure the load is axially aligned to prevent premature seal wear.
As a true ISO 15552 profile cylinder, this model serves as a drop-in replacement for any standard 100mm bore cylinder with a 185mm stroke, matching mounting interface dimensions exactly. It features a G1/2 port, PT thread type, and utilizes standard mounting accessories like FA flanges or TC trunnions. Remember that standard double-acting cylinders drift when air pressure is removed; if your application requires position holding without live pressure, consider the SAIL lock variant or an external rod lock.
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 SAI100X185S FAQ
At a standard operating pressure of 0.7 MPa, this 100mm bore cylinder generates 5497 N of push force and 3681 N of pull force. It can reach a maximum theoretical force of 801 kgf at 1.0 MPa.
Yes, the SAI100X185-S is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders with a 100mm bore and 185mm stroke, provided your mounting hardware and G1/2 port match.
