This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X195, 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 SI80X195 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 195mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X195, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI80X195 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 195 mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80X195, retaining the exact bore, stroke, force, port and mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This no-magnet SKU cannot take a sensor, unlike the CS1-B/DS1-B legacy switches used on -S models.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI80X195 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 SAI80X195 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).
Drives medium-force press operations for fitting bearings and pins, utilising the 2513 N push force at 0.5 MPa.
Actuates heavy-duty conveyor diverters and lane changers, benefiting from the 30-800 mm/s speed range.
To replace the SI80X195, order the SAI80X195. Verify the ISO 15552 mounting interface, G3/8 port, M20x1.5 rod thread and 36 mm cushions. Because this is a no-S SKU, it cannot accept a magnetic sensor. If sizing down, the 63 mm bore gives 1559 N push at 0.5 MPa; if sizing up, the 100 mm bore gives 3927 N. For load holding on air loss, note the cushion only decelerates; add an external rod lock, pilot check valve, or use the SAIL or BSAI lock variant. Stroke is under 300 mm so rod-bending side-load risks are minimal.
Replacement checklist
Yes, the SI80X195 is discontinued. The direct replacement is the AirTAC SAI80X195. It is dimensionally interchangeable per ISO 15552, matching the 80 mm bore, 195 mm stroke, 513 kgf max force, G3/8 port and mounting fixtures.
It features a G3/8 air port. Force output is 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI80X195 replacement — usually within 7-8 hours.
