About the Airtac SAI100 Standard Air Cylinder SAI100X15
The AirTAC SAI100X15 is a double-acting ISO 15552 profile cylinder engineered for high-force, short-stroke automation. Delivering a robust 3927 N of push force at just 0.5 MPa, it easily drives heavy clamping or pressing tasks within a tight 15 mm travel. The extruded aluminum barrel omits traditional tie-rods, presenting a clean exterior that drops directly into existing ISO 15552 mounting interfaces.
Because this 15 mm travel falls outside the standard manufactured stroke increments, it is supplied as a made-to-order non-standard stroke. The piston rod utilizes a carbon steel construction for standard industrial durability, and the body features sensor grooves on both sides for straightforward CMSE or DMSE switch installation. A PT tapered port thread ensures a positive, leak-free pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100X15 Is Used
Heavy Duty Clamping
Provides intense 3927 N clamping force at 0.5 MPa to secure heavy steel plates during machining or welding operations within a tight 15 mm travel.
Short-Stroke Pressing
Ideal for inserting bearings or pins into rigid housings, utilizing the 100 mm bore's high thrust capacity over a compact, non-standard 15 mm movement.
Rigid Stopper Block
Acts as a high-force mechanical stop on conveyor lines, using the robust carbon steel rod to halt heavy pallets without requiring long extension lengths.
Is the Airtac SAI100 Standard Air Cylinder SAI100X15 the Right Cylinder?
Choose this 100 mm bore when an application demands substantial thrust in a compact movement envelope, such as holding heavy weldments. If 3927 N at 0.5 MPa exceeds your actual requirement, stepping down to the 80 mm bore yields 2513 N, saving air volume and physical footprint. For this specific 15 mm non-standard stroke, confirm lead times during your RFQ.
Since the standard SAI is double-acting, it relies on continuous air pressure to maintain position; if the supply drops or the valve centers, the rod will drift. Do not depend on the end-of-stroke air cushions to hold a suspended load. For fail-safe vertical holding without live pressure, integrate an external pilot check valve or specify the SAIL locking variant. To replace an existing unit, match the 100 mm bore, 15 mm stroke, G1/2 port, and select mounting accessories like FA flanges or a TC trunnion.
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 SAI100X15 FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, the theoretical push force reaches 801 kgf.
Yes, the SAI100X15 is dimensionally interchangeable per ISO 15552. You can drop it into existing ISO 15552 mounting footprints and use matching FA, CA, or TC accessories, provided you match the G1/2 port size.
