This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63BX130, 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 SI63BX130
The AirTAC Airtac SI63 Standard Cylinder SI63BX130 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 SAI63BX130, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63BX130
The AirTAC SI63BX130 is a discontinued double-acting ISO 15552 profile cylinder with a 63 mm bore and 130 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa through a G3/8 port. This specific SKU features a SUS304 stainless steel rod for corrosion resistance but lacks a magnet, so it cannot accept position sensors.
AirTAC replaced it with the SAI63BX130 direct upgrade. It shares the exact ISO 15552 mounting interface, force, and cushions, but adds a two Y-shaped one-way piston seal for lower start-up pressure. Note that plain cylinders drift without air; use SAIL or BSAI lock variants for holding.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI63BX130 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAI63BX130 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI63 Standard Cylinder SI63BX130 Is Used
Stainless Rod Actuation
Ideal for packaging lines requiring washdown resistance, utilizing the SUS304 rod to push 1559 N loads at 0.5 MPa without corroding.
Replacing the Airtac SI63 Standard Cylinder SI63BX130 with the SAI63BX130
To replace this SI63BX130, order the SAI63BX130. Confirm the ISO 15552 mounting fixture, 130 mm stroke, G3/8 port, and SUS304 rod. Because this SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B switches; add the magnet if sensing is needed. Sizing both ways: the 63 mm bore yields 1559 N push at 0.5 MPa, sitting between the 50 mm (982 N) and 80 mm (2513 N) bores. The 130 mm stroke is under 300 mm so rod bending is minimal, but a plain cylinder drifts on air loss. For load holding, specify the SAIL lock or BSAI clamp-lock variant, or use an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63BX130
- ✓ 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 SI63BX130 FAQ
Yes, the SI63BX130 is discontinued. The direct replacement is the SAI63BX130. It is dimensionally interchangeable per the ISO 15552 mounting interface, maintaining the same 63 mm bore, 130 mm stroke, G3/8 port, and output force.
The G3/8 port feeds a 20 mm rod. Forces are 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 318 kgf theoretical max at 1.0 MPa. Note this -B variant has a SUS304 rod but no magnet for sensors.
