About the Airtac SAI63 Standard Cylinder SAI63AX60S
The AirTAC SAI63X60-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. The 60 mm stroke is optimal for short-travel clamping and indexing tasks. Because it is a profile barrel design, it omits external tie rods for a clean exterior.
This specific configuration includes a SUS420J2 stainless steel rod for enhanced durability against moisture. It also features a built-in magnet (-S) for use with CMSE and DMSE series reed switches, which seat directly into the dual sensor grooves on the barrel. Port threads are PT (tapered) per the required specification.

Where the Airtac SAI63 Standard Cylinder SAI63AX60S Is Used
Short-Stroke Clamping
Ideal for holding workpieces securely in machining fixtures where a 60 mm travel provides rapid actuation and 1559 N of clamping force at 0.5 MPa.
Package Diverting
Provides swift 60 mm strokes to push cartons off a main conveyor belt, utilizing the integrated magnet and DMSE sensors for precise end-position confirmation.
Material Gate Control
Actuates small hopper gates or discharge doors in bulk material handling, leveraging the SUS420J2 stainless steel rod to resist environmental wear.
Is the Airtac SAI63 Standard Cylinder SAI63AX60S the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore (982 N at 0.5 MPa) is insufficient, but an 80 mm bore (2513 N at 0.5 MPa) would overcompensate and waste energy. The 60 mm stroke keeps the retracted length compact for tight machinery layouts.
If your application requires holding a load vertically when air pressure is removed, note that the standard SAI will drift and drop. You must integrate an external pilot-operated check valve or step up to the SAIL (air-released lock) variant. For ISO 15552 interchangeability, match the 63 mm bore, 60 mm stroke, G3/8 port, and your preferred mounting accessory like the TC trunnion or FA flange.
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 SAI63AX60S FAQ
At a standard operating pressure of 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. It can reach up to 2182 N push at 0.7 MPa.
Yes, the SAI63X60-S is dimensionally interchangeable per ISO 15552. You can drop it in to replace other ISO 15552 profile cylinders by matching the 63 mm bore, 60 mm stroke, and G3/8 port size.
