This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X130SN, 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 SI63X130SN
The AirTAC Airtac SI63 Standard Cylinder SI63X130SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 130mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X130SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X130SN
The AirTAC SI63X130SN is a discontinued double-acting ISO 15552 profile cylinder with a 63mm bore and 130mm stroke, delivering 1559N push force at 0.5MPa. It is directly replaced by the SAI63X130SN. This direct upgrade shares the exact ISO 15552 mounting interface, G3/8 port, and M16x1.5 rod thread, fitting existing fixtures seamlessly.
The SAI upgrade features an improved piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The original -S magnet supports legacy CS1-B/DS1-B sensors, while the -N NBR seal operates from -20 to +70C (Viton H raises this to 150C).

Where the Airtac SI63 Standard Cylinder SI63X130SN Is Used
Mid-Tonnage Clamping
Secures heavy workpieces in CNC machining fixtures, utilizing the 1559N push force at 0.5MPa for rigid holding.
Package Diversion
Actuates sorting gates on high-speed packaging lines, with the 130mm stroke providing precise routing of goods.
Pallet Stop Arms
Controls pallet flow on roller conveyors, using the 79kg vertical lift capacity to manage heavy loads safely.
Replacing the Airtac SI63 Standard Cylinder SI63X130SN with the SAI63X130SN
To replace the discontinued SI63X130SN, order the SAI63X130SN. Verify the ISO 15552 mounting interface, G3/8 port, 130mm stroke, and your specific mounting accessory (LB, FA, TC, etc.). The -S magnet allows use of legacy CS1-B/DS1-B switches, and the -N denotes the NBR seal. When sizing, neighboring bores offer different forces: a 50mm bore provides 982N push, while an 80mm bore yields 2513N at 0.5MPa. Note that a standard cylinder does not hold load without live air; the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The SAI family also adds the SAIF self-valve option.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X130SN
- ✓ 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 SI63X130SN FAQ
Yes, the AirTAC SI63X130SN is discontinued. The direct replacement is the SAI63X130SN. It is dimensionally interchangeable per ISO 15552, retaining the same 63mm bore, 130mm stroke, output force, G3/8 port, and mounting accessories.
The 63mm bore features a G3/8 air port and M16x1.5 rod thread. Force output is 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, 2805N push at 0.9MPa, and a theoretical maximum of 318kgf at 1.0MPa. Operating speed is 30-800mm/s.
