About the Airtac SAI63 Standard Cylinder SAI63X30S
The AirTAC SAI63X30-S is a double-acting ISO 15552 profile cylinder engineered for short-stroke actuation. It delivers a robust 1559 N push force at 0.5 MPa, making it highly effective for compact, high-impact operations. The 30 mm stroke is optimal for rapid clamping and ejection tasks where minimal travel distance is required.
This genuine pneumatic component features a standard carbon steel piston rod and a built-in magnet (-S) for seamless integration with CMSE and DMSE series reed switches. The extruded aluminum barrel includes sensor grooves on both sides, while the PT tapered port threads guarantee a secure, leak-free pneumatic connection.

Where the Airtac SAI63 Standard Cylinder SAI63X30S Is Used
Short-Stroke Clamping
Ideal for holding heavy workpieces securely in machining fixtures using its 1559 N push force.
Product Diverting
Executes rapid 30 mm movements to push items off a production line with precise timing.
Ejector Mechanisms
Provides the necessary impact force to quickly eject finished parts from press beds.
Is the Airtac SAI63 Standard Cylinder SAI63X30S the Right Cylinder?
Selecting this 63 mm bore unit provides a balanced middle ground: it offers significantly more thrust than a 50 mm bore (982 N at 0.5 MPa) without the larger footprint of an 80 mm cylinder (2513 N at 0.5 MPa). The 30 mm stroke excels in tight spaces where only a brief actuation motion is necessary.
As a dimensionally interchangeable ISO 15552 profile cylinder, it serves as a direct drop-in replacement for other standard cylinders. To mount it, utilize standard accessories like LB foot brackets or FA flanges. Because the stroke is only 30 mm, side-load stress on the rod bearing is negligible, eliminating the need for external guides. Note that the standard SAI does not hold loads pneumatically; if your setup requires position holding without air pressure, consider the SAIL locking 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.
