About the Airtac SAI63 Standard Cylinder SAI63X15S
The AirTAC SAI63X15-S is a double-acting ISO 15552 profile cylinder engineered for compact actuation. It delivers a robust 1559 N push force at 0.5 MPa, making it well-suited for high-impact clamping and short-distance positioning tasks.
This specific configuration includes a magnet for proximity sensing, allowing seamless integration with CMSE or DMSE reed switches along the dual sensor grooves on the extruded aluminum barrel. The standard carbon steel piston rod ensures durable performance in demanding industrial environments.

Where the Airtac SAI63 Standard Cylinder SAI63X15S Is Used
Short-Stroke Clamping
Ideal for holding heavy machined components securely in place during milling or drilling operations using its 1559 N force.
Ejector Mechanism
Provides rapid, forceful ejection of parts from conveyor lines over short distances without requiring a long extension.
Press Fitting
Suitable for pressing small bearings or pins into housings where a brief, high-force stroke is required.
Is the Airtac SAI63 Standard Cylinder SAI63X15S the Right Cylinder?
Because this 15 mm stroke is shorter than the standard 25 mm minimum, it is classified as a made-to-order non-standard stroke. When selecting this model, verify that your mounting footprint accommodates the custom rod length. For applications requiring position holding without continuous air pressure, note that the standard adjustable air cushions only decelerate the piston at stroke ends and do not function as a lock; consider the SAIL variant for pneumatic locking requirements. This cylinder serves as a direct replacement matching ISO 15552 mounting dimensions, utilizing a PT G3/8 port and standard LB or FA 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 SAI63 Standard Cylinder SAI63X15S FAQ
At a standard operating pressure of 0.5 MPa, the SAI63X15-S generates a push force of 1559 N. At 0.7 MPa, the push force increases to 2182 N.
No, the standard SAI cylinder does not hold its position when air pressure is lost. The adjustable air cushion only decelerates the piston at the end of the stroke. For secure load holding, use the SAIL (air-released lock) or BSAI (clamp-lock) variants.
