About the Airtac SAI63 Standard Cylinder SAI63X105
The AirTAC SAI63X105 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 105mm stroke. It generates 1559N of push force at 0.5 MPa, making it well-suited for medium-duty industrial handling tasks. The extruded aluminum barrel omits tie-rods for a clean exterior while retaining standardized mounting dimensions.
This specific configuration utilizes a standard carbon steel piston rod and PT tapered port threads. Because a magnet is not specified, it operates without sensor detection capabilities. For high-temperature environments up to 70 C, the standard TPU seals provide reliable service, though Viton (H) alternatives are available if thermal limits are exceeded.

Where the Airtac SAI63 Standard Cylinder SAI63X105 Is Used
Parts Ejection
Provides 1559N of push force at 0.5 MPa to reliably eject finished metal components from machining centers.
Product Diverting
Actuates diverting arms along packaging lines, utilizing the 105mm stroke to shift goods between conveyor belts.
Pneumatic Clamping
Secures workpieces during light assembly operations where a compact 63mm profile is required.
Is the Airtac SAI63 Standard Cylinder SAI63X105 the Right Cylinder?
Choose this 63mm bore when 50mm models (982N push at 0.5 MPa) lack sufficient power, but 80mm units (2513N) would be physically oversized. The 105mm stroke is optimal for compact ejection or clamping tasks. Because the standard SAI lacks a position holding lock, the piston will drift if air pressure is lost; use the SAIL variant or an external rod lock for fail-safe vertical load suspension.
To replace an existing ISO 15552 cylinder, verify the 63mm bore, 105mm stroke, G3/8 port, and required mounting accessory (such as TC trunnion or FA flange). If your application requires magnetic position sensing, specify the -S magnet option.
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.
