This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63BX60, 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 SI63BX60
The AirTAC SI63 Standard Cylinder SI63BX60 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 60mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63BX60, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63BX60
The AirTAC SI63BX60 is a discontinued double-acting ISO 15552 profile cylinder featuring a 63 mm bore, 60 mm stroke, and a SUS304 stainless steel piston rod. It delivers 1559 N push force at 0.5 MPa through its G3/8 port. The direct replacement is the SAI63BX60, which maintains the exact ISO 15552 mounting interface, bore, stroke, and output force.
The current-production SAI upgrade introduces an improved piston seal with two Y-shaped one-way elements for lower start-up pressure and extended life. Because this specific SI63BX60 SKU lacks a magnet, it cannot accept position sensors. For load-holding, note that standard cylinders drift without live air; consider an external pilot check valve or the SAIL lock variant.

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 SAI63BX60 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 SI63BX60 Is Used
Stainless Rod Clamping
Ideal for packaging or food-grade machinery where the SUS304 rod resists washdown corrosion while providing 1559 N of clamping thrust.
Compact Ejection
Fits tightly into material handling cells to eject 79 kg vertical loads, dropping easily into existing ISO 15552 fixtures.
Replacing the Airtac SI63 Standard Cylinder SI63BX60 with the SAI63BX60
To replace the discontinued SI63BX60, order the SAI63BX60. Verify your ISO 15552 mounting accessories (LB, FA, TC, etc.) and confirm the G3/8 port threads. This unit uses a SUS304 stainless rod for corrosion resistance. Since it has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors; order a magnet-equipped SAI if sensing is required. For sizing, the 63 mm bore yields 1559 N push at 0.5 MPa; if less force is needed, a 50 mm bore offers 982 N, or an 80 mm bore provides 2513 N. Remember that a plain cylinder does not hold load without air pressure; for dead-load holding, explore the SAIL or BSAI lock variants. At a 60 mm stroke, side-load risks are minimal, but always ensure proper alignment to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63BX60
- ✓ 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 SI63BX60 FAQ
Yes, the AirTAC SI63BX60 is discontinued. The direct replacement is the SAI63BX60. It is dimensionally interchangeable per ISO 15552, keeping the same 63 mm bore, 60 mm stroke, G3/8 port, and mounting interface.
It features a G3/8 air port and provides 1559 N push and 1402 N pull at 0.5 MPa. At 0.7 MPa push is 2182 N, and at 0.9 MPa it is 2805 N. The theoretical maximum force is 318 kgf at 1.0 MPa.
