This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X132S, 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 SI63X132S
The AirTAC Airtac SI63 Standard Cylinder SI63X132S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 132mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X132S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X132S
The AirTAC SI63X132S is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore and 132 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa. AirTAC replaced this legacy unit with the SAI63X132S, a direct upgrade sharing the exact ISO 15552 mounting interface, G3/8 port, and M16x1.5 rod thread.
The SAI successor features an upgraded piston seal using two Y-shaped one-way elements for low start-up pressure and extended life. This -S variant includes a piston magnet for legacy CS1-B/DS1-B sensors, while the SAI family also introduces SAIL, SAIF, and BSAI lock or valve variants absent from the SI line.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI63X132S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAI63X132S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI63 Standard Cylinder SI63X132S Is Used
Mid-Tonnage Clamping
Secures heavy workpieces in machining fixtures using 1559 N of push force at 0.5 MPa.
Package Diversion
Actuates routing gates on high-speed material handling lines with a 132 mm stroke.
Replacing the Airtac SI63 Standard Cylinder SI63X132S with the SAI63X132S
To replace the SI63X132S, order the SAI63X132S keeping the identical 63 mm bore, 132 mm stroke, and -S magnet. Confirm the ISO 15552 mounting accessory (LB, FA, TC, etc.) and your G3/8 port thread (PT, G, or NPT). If you need more force, the neighboring 80 mm bore yields 2513 N push at 0.5 MPa; if downsizing, the 50 mm bore offers 982 N. Note that a standard cylinder drifts without live air—the cushion only decelerates—so for load holding consider the SAIL lock, BSAI clamp-lock, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X132S
- ✓ 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 SI63X132S FAQ
Yes, the SI63X132S is discontinued. The direct replacement is the AirTAC SAI63X132S. It is dimensionally interchangeable per ISO 15552, retaining the same 63 mm bore, 132 mm stroke, output force, G3/8 port, and mounting interface.
The 63 mm bore features a G3/8 air port and an M16x1.5 rod thread. 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.
