This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X230TC, 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 SI80 Standard Air Cylinder SI80X230TC
The AirTAC SI80 Standard Air Cylinder SI80X230TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 230mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X230TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X230TC
The AirTAC SI80X230TC is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore, 230 mm stroke, and a TC trunnion mount. Generating 2513 N of push force at 0.5 MPa, it features a 25 mm rod, M20x1.5 thread, and 36 mm adjustable air cushions at both ends. As this SKU lacks the -S magnet, it cannot accept a position sensor. The direct replacement is the SAI80X230TC, which preserves the exact ISO 15552 mounting interface, bore, stroke, output force, and G3/8 port size.
The SAI upgrade introduces an upgraded piston seal utilizing two Y-shaped one-way elements for low start-up pressure and extended life. For applications requiring load holding on air loss, note that a standard cylinder drifts and its cushion only decelerates; you would need the SAIL or BSAI lock variants.

Where the Airtac SI80 Standard Air Cylinder SI80X230TC Is Used
Pallet Diversion
Actuates a TC-mounted routing arm on a packaging line to divert heavy pallets, utilizing the 2513 N push force at 0.5 MPa to overcome lateral friction.
Press Ejection
Ejects formed metal components from a hydraulic press fixture, requiring the robust 80 mm bore and M20x1.5 rod thread to withstand repetitive impact loads.
Replacing the Airtac SI80 Standard Air Cylinder SI80X230TC with the SAI80X230TC
To replace the discontinued SI80X230TC, order the SAI80X230TC. Verify that your existing fixture uses the ISO 15552 TC trunnion mounting interface, and confirm the 80 mm bore, 230 mm stroke, and G3/8 port. Because this specific legacy SKU lacks the -S magnet option, it cannot support a sensor; if position detection is needed, order the SAI equivalent with the S suffix for current AirTAC switches. When sizing, consider neighboring bores: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore provides 3927 N. For this 230 mm stroke, ensure adequate guide support to prevent rod bending and side-load damage. Finally, a plain cylinder does not hold load without live air—the cushion only decelerates—so for suspended loads use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X230TC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI80 Standard Air Cylinder SI80X230TC FAQ
Yes, the AirTAC SI80X230TC is discontinued and end-of-life. The direct replacement is the SAI80X230TC. It is dimensionally interchangeable per the ISO 15552 mounting interface, maintaining the identical 80 mm bore, 230 mm stroke, output force, G3/8 port, and TC trunnion mount. You simply order the SAI model for your existing fixtures.
The 80 mm bore utilizes a G3/8 air port. At 0.5 MPa it provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa the push force is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
