This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X192SN, 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 SI63X192SN
The AirTAC Airtac SI63 Standard Cylinder SI63X192SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 192mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X192SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X192SN
The AirTAC SI63X192SN is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore and 192 mm stroke. It delivers 1559 N push force at 0.5 MPa through a G3/8 port. AirTAC replaced this unit with the SAI63X192SN, a direct sharing the same interface, force, and mounting.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. It also adds SAIL, SAIF, and BSAI lock variants the SI lacked. This -S magnet model takes CS1-B/DS1-B switches, and the -N NBR seal operates from -20 to +70 C.

Where the Airtac SI63 Standard Cylinder SI63X192SN Is Used
Clamping Fixtures
Secures mid-weight machined parts during milling, using the 1559 N push force to hold components firmly against locators.
Package Diverting
Actuates routing gates on packaging lines, where the 192 mm stroke provides sufficient travel to redirect cartons between belts.
Replacing the Airtac SI63 Standard Cylinder SI63X192SN with the SAI63X192SN
To replace the SI63X192SN, order the SAI63X192SN direct, verifying the ISO 15552 mounting interface, 63 mm bore, 192 mm stroke, G3/8 port, and your specific mounting accessory. The built-in magnet (-S) works with CS1-B/DS1-B sensors, while the SAI uses current AirTAC switches. For sizing, a 50 mm bore yields 982 N push at 0.5 MPa, whereas an 80 mm bore yields 2513 N. Note that a plain cylinder drifts on air loss since cushions only decelerate; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 192 mm stroke, rod bending is minimal, but ensure guide alignment to prevent side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X192SN
- ✓ 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 SI63X192SN FAQ
Yes, the SI63X192SN is discontinued. The direct replacement is the SAI63X192SN. It is dimensionally interchangeable per ISO 15552, retaining the same 63 mm bore, 192 mm stroke, output force, G3/8 port, and mounting interface.
This 63 mm bore cylinder uses a G3/8 air port. The thrust ratings are: 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.
