This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX475S, 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 SI160 Standard Cylinder SI160AX475S
The AirTAC SI160 Standard Cylinder SI160AX475S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 475mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX475S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX475S
The AirTAC SI160AX475S is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore and 475 mm stroke. It delivers a push force of 10053 N at 0.5 MPa, utilizing a G3/4 air port and an M36x2 rod thread. The direct replacement is the SAI160AX475S, which preserves the original ISO 15552 mounting interface, bore, stroke, and output force for seamless fixture integration.
The SAI upgrade introduces an advanced piston seal with two Y-shaped one-way elements, ensuring low start-up pressure and extended service life. This specific SI configuration includes a SUS420J2 stainless steel piston rod for corrosion resistance and a built-in magnet for legacy CS1-B/DS1-B sensors.

Where the Airtac SI160 Standard Cylinder SI160AX475S Is Used
Pallet Handling
Indexes heavy loaded pallets along conveyor lines, utilizing the 475 mm stroke to push bulky assemblies securely.
Automated Assembly Lift
Elevates massive automotive subframes during multi-stage assembly, relying on external guides to manage the 475 mm extension.
Replacing the Airtac SI160 Standard Cylinder SI160AX475S with the SAI160AX475S
To replace the discontinued SI160AX475S, order the SAI160AX475S, confirming the ISO 15552 mounting interface, 160 mm bore, 475 mm stroke, G3/4 port, and the -S magnet for current AirTAC switches. When sizing both ways, verify if neighboring bores (like 125 mm or 200 mm) fit your force requirements, noting this 160 mm bore provides 10053 N push at 0.5 MPa. Because the 475 mm stroke is substantial, implement external guides to prevent rod bending and side-load damage. A plain cylinder does not hold load on air loss; the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX475S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI160 Standard Cylinder SI160AX475S FAQ
Yes, the SI160AX475S is discontinued. The direct replacement is the SAI160AX475S. It is dimensionally interchangeable per the ISO 15552 mounting interface, maintaining the same 160 mm bore, 475 mm stroke, output force, G3/4 port, and mounting accessories.
This double-acting cylinder operates at 0.15-1.0 MPa with a speed of 30-500 mm/s.
