Airtac SAI63 Standard Cylinder SAI63AX130
The AirTAC Airtac SAI63 Standard Cylinder SAI63AX130 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø63mm bore and 130mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAI63 Standard Cylinder SAI63AX130
The AirTAC SAI63X130 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 130 mm stroke is well-suited for mid-range extension tasks requiring consistent, balanced power. The extruded aluminum barrel omits traditional tie-rods, providing a clean exterior that resists debris accumulation.
This configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It utilizes PT tapered port threads and lacks a standard magnet, meaning it relies on external sensors if position detection is required. The adjustable air cushions at both ends decelerate the piston effectively to minimize impact wear.

Where the Airtac SAI63 Standard Cylinder SAI63AX130 Is Used
Package Diversion
Provides the 1559 N force needed to reliably push heavy packages onto secondary conveyor lines at sorting centers.
Component Clamping
Secures metal or plastic parts during machining operations, utilizing the 130 mm stroke to accommodate varying workpiece sizes.
Gate Control
Actuates security gates or heavy industrial barriers where consistent mid-range force and smooth pneumatic cushioning are required.
Is the Airtac SAI63 Standard Cylinder SAI63AX130 the Right Cylinder?
If your application requires slightly less force, stepping down to the 50 mm bore yields 982 N at 0.5 MPa, while moving up to the 80 mm bore provides 2513 N for heavier payloads. As a genuine ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders, matching the 63 mm bore, 130 mm stroke, G3/8 port, and standard mounting accessories like FA flanges or TC trunnions.
Note that a standard SAI cylinder does not hold its position if air pressure is lost; the piston will drift. For applications requiring dead-load holding without live pressure, consider the SAIL variant with an air-released lock or an external rod lock mechanism.
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.
