About the Airtac SAI63 Standard Cylinder SAI63AX5
The AirTAC SAI63X5 is a double-acting ISO 15552 profile cylinder engineered for ultra-short travel requirements. Delivering a push force of 1559 N at 0.5 MPa, this 63mm bore unit utilizes a 5mm stroke, making it a specialized made-to-order solution for compact clamping and ejection tasks.
Configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance, it features an extruded aluminum barrel with dual sensor grooves. Note that for position feedback, a magnet (-S) must be specified. The PT tapered port threads ensure a robust, sealed pneumatic connection.

Where the Airtac SAI63 Standard Cylinder SAI63AX5 Is Used
Precision Part Clamping
Ideal for securing workpieces in tight machining fixtures where only a few millimeters of travel are needed to lock the component in place.
Product Ejection
Provides a rapid, short-thrust push to eject small parts off a conveyor line without extending into adjacent machinery lanes.
Valve Actuation
Suitable for toggling mechanical valves or operating small mechanical latches where a full 25mm stroke would cause mechanical binding.
Is the Airtac SAI63 Standard Cylinder SAI63AX5 the Right Cylinder?
This 5mm stroke is a non-standard, made-to-order configuration designed for extremely tight spaces where a standard 25mm stroke would bottom out or require excessive clearance. If your application needs slightly more travel or standard availability, stepping down to the SAI50X25 (825 N pull at 0.5 MPa) or using a standard 25mm stroke on this 63mm bore is advised.
Because this is a double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered; the piston will drift. For fail-safe load holding, consider the SAIL (air-released lock) variant or an external pilot-operated check valve. Ensure your ISO 15552 mounting interface matches your existing foot (LB) or flange (FA) 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 SAI63AX5 FAQ
