This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X130SFA, 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 SI63X130SFA
The AirTAC Airtac SI63 Standard Cylinder SI63X130SFA 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 SAI63X130SFA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X130SFA
The AirTAC SI63X130SFA is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore and 130 mm stroke. It delivers 1559 N push force at 0.5 MPa through a G3/8 port. AirTAC replaced this legacy unit with the SAI63X130SFA, a direct upgrade retaining the exact FA flange mount, M16x1.5 rod thread, and output force.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also introduces lock and clamp variants (SAIL, BSAI) absent in the SI line. This -S SKU includes a piston magnet for CS1-B/DS1-B switches.

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 SI63X130SFA Is Used
Press Fit Assembly
Drives bearings or pins with 1559 N push force at 0.5 MPa, providing stable insertion for medium-duty automated fitting stations.
Pallet Diversion
Actuates routing gates or stops on conveyor lines using the FA flange mount to handle packaging traffic reliably.
Replacing the Airtac SI63 Standard Cylinder SI63X130SFA with the SAI63X130SFA
To replace the SI63X130SFA, order the SAI63X130SFA. Verify the ISO 15552 interface, 63 mm bore, 130 mm stroke, G3/8 port, and FA flange mounting. The -S magnet is present for position sensing; use current AirTAC switches for the SAI (legacy SI used CS1-B/DS1-B). For sizing, the 63 mm bore yields 1559 N push at 0.5 MPa; dropping to a 50 mm bore gives 982 N, while an 80 mm bore provides 2513 N. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external pilot check valve, rod lock, or the SAIL/BSAI variants. At 130 mm stroke, rod bending is minimal, but ensure guide alignment to prevent side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X130SFA
- ✓ 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 SI63X130SFA FAQ
Yes, the SI63X130SFA is discontinued. The direct replacement is the SAI63X130SFA. It shares the identical ISO 15552 mounting interface, 63 mm bore, 130 mm stroke, output force, G3/8 port, and FA flange, fitting directly into existing fixtures.
This 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 force of 318 kgf at 1.0 MPa.
