This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI63BX160SH, 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 SI63BX160SH
The AirTAC Airtac SI63 Standard Cylinder SI63BX160SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI63BX160SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI63 Standard Cylinder SI63BX160SH
The AirTAC SI63BX160SH is a discontinued double-acting ISO 15552 profile cylinder featuring a 63 mm bore and 160 mm stroke. This legacy unit delivers 1559 N push force at 0.5 MPa, includes a SUS304 stainless piston rod for corrosion resistance, a high-temp Viton H seal rated for 0-150 C, and a G3/8 port. The direct replacement is the SAI63BX160SH, sharing the exact ISO 15552 mounting interface, force, and stroke.
The SAI upgrade introduces an advanced piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The original -S magnet supports CS1-B/DS1-B sensors, while the SAI family expands options with SAIL lock and BSAI clamp-lock variants.

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 SAI63BX160SH 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 SI63BX160SH Is Used
Hot Stamp Presses
Drives tooling in elevated-temperature stamping environments where the Viton H seal and SUS304 rod resist thermal degradation and corrosion.
Divert & Stop Gates
Actuates heavy-duty diverting arms on packaging lines, utilising the 1559 N push force to reliably shift loads at 0.5 MPa.
Replacing the Airtac SI63 Standard Cylinder SI63BX160SH with the SAI63BX160SH
To replace the discontinued SI63BX160SH, order the SAI63BX160SH ensuring the ISO 15552 mounting interface, 63 mm bore, 160 mm stroke, G3/8 port, and magnet are retained. Confirm your rod material (-B SUS304) and seal (-H Viton) requirements. If you need more force, the neighbouring 80 mm bore yields 2513 N push at 0.5 MPa; if less is acceptable, the 50 mm bore provides 982 N. Note that a plain cylinder drifts on air loss as the cushion only decelerates at stroke end; for load holding, specify the SAIL or BSAI lock variant, or use an external pilot check valve. At 160 mm stroke, side-load risks are low, but ensure standard guide alignment to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI63BX160SH
- ✓ 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 SI63BX160SH FAQ
Yes, the SI63BX160SH is discontinued. The direct replacement is the SAI63BX160SH. It is dimensionally interchangeable per ISO 15552, matching the 63 mm bore, 160 mm stroke, G3/8 port, and mounting interface, but features an upgraded two Y-shaped element piston seal for longer life.
The 63 mm bore uses a G3/8 port. At 0.5 MPa it provides 1559 N push and 1402 N pull force. At 0.7 MPa the push force is 2182 N, and at 0.9 MPa it is 2805 N. The theoretical maximum force is 318 kgf at 1.0 MPa.
