About the Airtac SAI63 Standard Cylinder SAI63X15
The AirTAC SAI63X15 is a double-acting ISO 15552 profile cylinder featuring a highly compact 15 mm stroke. It delivers a robust 1559 N of push force at 0.5 MPa, making it ideal for high-force clamping in very tight spaces. This made-to-order stroke ensures you get the exact travel required for specialized machinery.
Standard configuration includes a durable carbon steel piston rod and PT (tapered) G3/8 ports. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing you to easily mount CMSE or DMSE switches for position feedback.

Where the Airtac SAI63 Standard Cylinder SAI63X15 Is Used
High-Force Clamping
Secures heavy metal workpieces during CNC machining operations where a short 15 mm travel is sufficient.
Short-Stroke Ejection
Quickly pushes finished parts out of a press mold in confined automated assembly cells.
Compact Positioning
Acts as a rugged stopper or positioning pin in material handling systems requiring high holding strength.
Is the Airtac SAI63 Standard Cylinder SAI63X15 the Right Cylinder?
Choose this 63 mm bore when you need significantly more thrust than a 50 mm bore provides, which only yields 982 N at 0.5 MPa. The 15 mm stroke is a non-standard made-to-order dimension, ensuring precise short-travel movements without excess rod length. Because the stroke is so short, side-load stress on the rod bearing is minimal compared to longer strokes.
This model is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 profile cylinders. It features a PT G3/8 port, a standard carbon steel rod, and no magnet. If your application requires the load to stay held without live air pressure, use the SAIL 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 SAI63 Standard Cylinder SAI63X15 FAQ
At a 0.5 MPa operating pressure, the SAI63X15 provides 1559 N of push force and 1402 N of pull force.
Yes, it shares the standard ISO 15552 mounting interface, allowing it to drop in as a replacement for other ISO 15552 profile cylinders without modifying the mounting footprint.
