This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X700SH, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SI63 Standard Cylinder SI63X700SH
The AirTAC Airtac SI63 Standard Cylinder SI63X700SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 700mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X700SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X700SH
The AirTAC SI63X700SH is a discontinued double-acting ISO 15552 profile cylinder featuring a 63mm bore, 700mm stroke, G3/8 port, and an integrated magnet. Generating 1559N push force at 0.5MPa, it is directly replaced by the SAI63X700SH. This direct upgrade shares the exact ISO 15552 mounting interface, bore, stroke, output force, and port size, fitting existing fixtures perfectly.
The SAI successor upgrades the piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. This -H variant specifies a Viton FKM seal, elevating the operating temperature range from -20 to +70C up to 0-150C. The built-in magnet supports legacy CS1-B/DS1-B switches, while the SAI family utilizes current AirTAC sensors.

Where the Airtac SI63 Standard Cylinder SI63X700SH Is Used
High-Temp Ejection
Deploy the Viton -H seal to eject molded parts near hot machinery, utilizing the 1559N push force at 0.5MPa without thermal degradation up to 150C.
Pallet Transfer
Actuate heavy pallet stops or diverter arms over a 700mm reach, relying on the G3/8 port and adjustable 30mm air cushions for smooth end-of-stroke deceleration.
Replacing the Airtac SI63 Standard Cylinder SI63X700SH with the SAI63X700SH
To replace the discontinued SI63X700SH, order the SAI63X700SH, confirming the ISO 15552 mounting interface, 63mm bore, 700mm stroke, G3/8 port, and Viton -H high-temperature seal. The SAI family also introduces lock variants the SI lacked, such as the SAIL air-released lock and BSAI clamp-lock. For sizing alternatives, a neighbouring 80mm bore offers higher force (2513N push at 0.5MPa), while dropping to 0.5MPa on the 63mm bore still yields 1559N. A plain cylinder does not hold load without live air; the cushion only decelerates, so use an external rod lock or pilot check valve for secure holding. Because the 700mm stroke is long, prevent rod bending by guiding the load externally to avoid side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X700SH
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI63 Standard Cylinder SI63X700SH FAQ
Yes, the SI63X700SH is discontinued. The direct replacement is the SAI63X700SH. It shares the same ISO 15552 mounting interface, 63mm bore, 700mm stroke, output force, and G3/8 port, dropping directly into existing fixtures.
The 63mm bore features a G3/8 air port and M16x1.5 rod thread. It delivers 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, 2805N push at 0.9MPa, and a theoretical maximum force of 318kgf at 1.0MPa.
