This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63AX130, 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 SI63AX130
The AirTAC Airtac SI63 Standard Cylinder SI63AX130 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 SAI63AX130, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63AX130
The AirTAC SI63AX130 is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore and 130 mm stroke. It delivers a push force of 1559 N at 0.5 MPa via a G3/8 port. The direct replacement is the SAI63AX130, which matches the exact interface, stroke, force, and mounting hardware.
This SKU features a SUS420J2 stainless steel rod (-A) but lacks a magnet, so it cannot accept a CS1-B or DS1-B sensor. The SAI upgrade uses two Y-shaped piston seals for low start-up pressure. For load holding, note the cushion only decelerates; use a SAIL lock or external check valve.

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 SI63AX130 Is Used
Stainless Rod Actuation
Leverages the SUS420J2 rod for mid-force clamping tasks in washdown or mildly corrosive settings, providing 1559 N push at 0.5 MPa.
Transfer Diverting
Drives 63 mm bore diverters and gates on production lines, benefiting from the 30-800 mm/s speed range and adjustable end cushions.
Replacing the Airtac SI63 Standard Cylinder SI63AX130 with the SAI63AX130
To replace the SI63AX130, order the SAI63AX130. Verify the ISO 15552 mounting interface, 130 mm stroke, G3/8 port (PT/G/NPT), and the -A SUS420J2 rod. Because this SKU has no -S magnet, it cannot support position sensing; if switches are needed, specify a magnet on the SAI order. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding consider the SAIL lock, BSAI clamp-lock, or an external pilot check valve. At 130 mm stroke, side-load is minimal, but always ensure rigid alignment.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63AX130
- ✓ 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 SI63AX130 FAQ
Yes, the SI63AX130 is discontinued. The direct replacement is the SAI63AX130. It is dimensionally interchangeable per ISO 15552, retaining the same 63 mm bore, 130 mm stroke, 1559 N force, G3/8 port, and mounting interface.
This double-acting cylinder has a 20 mm rod, M16x1.5 thread, 30 mm cushions, and operates at 30-800 mm/s. Force ratings are: push 1559 N and pull 1402 N at 0.5 MPa, push 2182 N at 0.7 MPa, push 2805 N at 0.9 MPa, and a theoretical max of 318 kgf at 1.0 MPa.
