This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80AX130, 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.

The AirTAC SI80 Standard Air Cylinder SI80AX130 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 130mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80AX130, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI80AX130 is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 130mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa via a G3/8 port. The direct is the SAI80AX130, retaining identical mounting and force. This SKU uses an SUS420J2 stainless rod and lacks a magnet, so it cannot accept switches.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure. For high heat, Viton H seals raise limits to 150C.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI80AX130 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAI80AX130 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Applies 2513N of thrust at 0.5MPa for seating bearings or light stamping tasks on automated lines.
Drives robust routing gates or pushers handling substantial pallets across material transport systems.
Acts as a high-force physical stop or lift gate in distribution hubs, safely managing 128kg vertical loads.
To replace the SI80AX130, order SAI80AX130. Verify the ISO 15552 interface, 80mm bore, 130mm stroke, G3/8 port, and SUS420J2 rod. Because this SKU has no magnet (-S), it cannot support legacy CS1-B/DS1-B sensors. Sizing up, a 100mm bore yields 3927N push at 0.5MPa; sizing down, a 63mm bore gives 1559N. Air cushions only decelerate; for load holding on air loss, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
Yes, the SI80AX130 is discontinued. The direct replacement is the SAI80AX130. It is a true ISO 15552 profile cylinder with the same 80mm bore, 130mm stroke, G3/8 port, and mounting interface, but features an upgraded two Y-shaped one-way piston seal for longer life.
It features a G3/8 air port and M20x1.5 rod thread. Force output is 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N push at 0.9MPa, and a theoretical maximum of 513kgf at 1.0MPa.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI80AX130 replacement — usually within 7-8 hours.
