This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X470, 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 SI63X470
The AirTAC Airtac SI63 Standard Cylinder SI63X470 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 470mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X470, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X470
The AirTAC SI63X470 is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore and 470 mm stroke. It delivers 1559 N push force at 0.5 MPa through a G3/8 port. AirTAC replaced this legacy unit with the SAI63X470, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, and force.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note this specific SKU lacks a magnet (-S) and cannot accept position sensors.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |

Where the Airtac SI63 Standard Cylinder SI63X470 Is Used
Material Diversion
Actuates routing gates on package lines, utilizing the 1559 N push force to deflect heavy cartons reliably at high cycle rates.
Pallet Handling
Drives 470 mm stroke pushers to index pallets into wrapping stations, requiring external guides to manage the long rod extension.
Replacing the Airtac SI63 Standard Cylinder SI63X470 with the SAI63X470
To replace the SI63X470, order the SAI63X470. Verify your ISO 15552 mounting accessory (LB, FA, TC, etc.), the G3/8 port thread (PT, G, or NPT), and the M16x1.5 rod-end connection. Because this 470 mm stroke exceeds 300 mm, use external guides to prevent rod bending and premature seal wear from side loads. If sizing up or down, neighboring bores (50 mm or 80 mm) offer 982 N or 2513 N push at 0.5 MPa. This non-magnetic model cannot host CS1-B or DS1-B sensors; if sensing is needed, specify an SAI with the -S magnet option. For load holding on air loss, the cushion only decelerates; you must use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X470
- ✓ 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 SI63X470 FAQ
Yes, the SI63X470 is discontinued. The direct replacement is the AirTAC SAI63X470. It is dimensionally interchangeable per ISO 15552, matching the 63 mm bore, 470 mm stroke, G3/8 port, and mounting interface, so it drops directly into existing fixtures.
This 63 mm bore double-acting cylinder uses a G3/8 air 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. It operates at speeds of 30-800 mm/s.
