This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X960S, 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 SI63X960S
The AirTAC Airtac SI63 Standard Cylinder SI63X960S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 960mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X960S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X960S
The AirTAC SI63X960S is a discontinued double-acting ISO 15552 profile cylinder with a 63mm bore and 960mm stroke. Delivering 1559 N push at 0.5 MPa via a G3/8 port, it is replaced by the SAI63X960S. This direct successor matches the exact ISO 15552 mounting interface, bore, stroke, force and accessories.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. The SI -S magnet works with legacy CS1-B/DS1-B sensors, while SAIL lock and BSAI clamp-lock variants expand held-load options.

Where the Airtac SI63 Standard Cylinder SI63X960S Is Used
Long-Stroke Diversion
Drives a 960mm pusher arm to reroute heavy packages on a packaging line, utilizing the 1559 N thrust at 0.5 MPa.
Large Press Ejection
Extends fully to clear stamped parts from a wide press bed, relying on adjustable 30mm cushions to decelerate the rod.
Replacing the Airtac SI63 Standard Cylinder SI63X960S with the SAI63X960S
To replace the SI63X960S, order the SAI63X960S. Verify the ISO 15552 interface, 63mm bore, 960mm stroke, G3/8 port (PT/G/NPT), M16x1.5 rod thread and mounting accessory. The -S magnet enables CS1-B/DS1-B sensors. For sizing, a 50mm bore yields 982 N [email protected], while an 80mm bore yields 2513 N. A plain cylinder drifts on air loss; use a pilot check valve or SAIL/BSAI lock for holding. At 960mm, prevent rod bending with external guides to manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X960S
- ✓ 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 SI63X960S FAQ
Yes, the SI63X960S is discontinued. The direct replacement is the SAI63X960S. It is dimensionally interchangeable per ISO 15552, retaining the same 63mm bore, 960mm stroke, output force, G3/8 port and mounting fixtures.
The 63mm bore features a G3/8 port. It generates 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N push at 0.9 MPa, and a theoretical maximum of 318 kgf at 1.0 MPa.
