This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63X730SH, 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 SI63X730SH
The AirTAC Airtac SI63 Standard Cylinder SI63X730SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 730mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63X730SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63X730SH
The AirTAC SI63X730SH is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore and 730 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa through a G3/8 port. The direct replacement is the SAI63X730SH, matching the interface, force, and mounting.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure. The -H seal allows 0-150 C Viton operation, and the -S magnet works with 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 SI63X730SH Is Used
Long-Stroke Diversion
Pushes packages across transfer lines using the 730 mm travel, relying on the 1559 N thrust to overcome lateral friction.
High-Temp Actuation
Actuates gates near heat zones using the Viton H seal rated for 0-150 C, with the magnet for position tracking.
Replacing the Airtac SI63 Standard Cylinder SI63X730SH with the SAI63X730SH
To replace the SI63X730SH, order the SAI63X730SH. Verify the ISO 15552 mounting interface, 63 mm bore, 730 mm stroke, G3/8 port, and magnet. If you need more force, the 80 mm bore offers 2513 N push at 0.5 MPa; if less is needed, the 50 mm bore gives 982 N. Because 730 mm exceeds 300 mm, use an external guide to prevent rod bending and side loads. For load holding on air loss, use an external pilot check valve or the SAIL/BSAI lock variant, as cushions only decelerate.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63X730SH
- ✓ 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 SI63X730SH FAQ
Yes, the SI63X730SH is discontinued. The direct replacement is the SAI63X730SH, which is dimensionally interchangeable per ISO 15552 with the same bore, stroke, force, G3/8 port, and mounting.
The 63 mm bore uses a G3/8 port. It provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N at 0.9 MPa, and a max force of 318 kgf at 1.0 MPa.
