About the Airtac SAI100 Standard Air Cylinder SAI100AX185S
The AirTAC SAI100X185-S is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and 185mm stroke. It delivers a robust 3927 N push force at 0.5 MPa, making it well-suited for heavy-duty pressing and lifting tasks. This specific configuration includes a SUS420J2 stainless steel rod for enhanced corrosion resistance and a magnet for position sensing.
Because it adheres to the ISO 15552 mounting interface, this extruded aluminum barrel cylinder serves as a drop-in replacement for other ISO 15552 profile cylinders. The integrated magnet allows seamless use with CMSE or DMSE sensor switches fitted into the dual side grooves. It also features PT tapered port threads and adjustable air cushions at both ends to manage impact deceleration.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX185S Is Used
Heavy-Duty Stamping
Provides the necessary 3927 N thrust at 0.5 MPa for securely stamping and forming rigid metal components.
Pallet Diversion
Handles high-mass product routing on conveyor lines where substantial side-load resistance and pushing power are required.
Automated Pressing
Ideal for pressing bearings or pins into housings, utilizing the full 185mm stroke and adjustable end cushions.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX185S the Right Cylinder?
Choose this 100mm bore when an 80mm bore (providing 2513 N at 0.5 MPa) is insufficient for your load, but a 125mm bore (6136 N at 0.5 MPa) would be excessive. For applications requiring position holding without live air pressure, note that the standard air cushion only decelerates the piston near stroke end and does not act as a lock. In such cases, consider the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder.
To replace an existing ISO 15552 cylinder, match the 100mm bore, 185mm stroke, PT G1/2 ports, and your required mounting accessory (such as FA flange or TC trunnion). The -S suffix indicates the piston magnet is pre-installed for immediate sensor integration.

- ✓ 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 SAI100AX185S FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes, it uses the standardized ISO 15552 mounting interface, meaning it is dimensionally interchangeable with other ISO 15552 profile cylinders. You can use standard FA, FB, CA, or TC mounting accessories.
