This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X95, 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 SI80X95 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 95mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X95, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI80X95 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 95 mm stroke. It delivers 2513 N of push force at 0.5 MPa through its G3/8 air port. Because this SI unit is end-of-life, you should order the direct replacement: the SAI80X95. It shares the same interface, bore, stroke, force, port and mounting hardware, fitting directly into your existing fixtures.
The SAI upgrade introduces a refined piston seal using two Y-shaped one-way elements for extended life and lower start-up pressure. Note that this specific SKU lacks the -S magnet, so it cannot accept a CS1-B or DS1-B sensor.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI80X95 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 SAI80X95 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).
Provides 2513 N of push force at 0.5 MPa to reliably eject formed metal parts from heavy stamping dies.
Executes 95 mm strokes to push heavy pallets onto secondary packaging lines without requiring long travel distances.
Acts as a robust physical stop for 128 kg vertical lift loads, utilising its 80 mm bore and M20x1.5 rod threading.
To replace the discontinued SI80X95, order the SAI80X95. Verify your ISO 15552 mounting accessory (LB foot, FA flange, TC trunnion) and confirm the G3/8 port thread (PT, G or NPT). Because this SKU lacks the -S magnet, it cannot support position sensing; if you require switches, select an SAI80X95S and use current AirTAC sensors. If you need to size up or down, neighbouring bores are 63 mm (1559 N push @0.5 MPa) and 100 mm (3927 N push @0.5 MPa). A plain cylinder does not hold load on air loss; for suspended loads use the SAIL or BSAI lock variant, or an external pilot check valve.
Replacement checklist
Yes, the AirTAC SI80X95 is discontinued. The direct replacement is the SAI80X95. It is dimensionally interchangeable per ISO 15552, retaining the same 80 mm bore, 95 mm stroke, output force, G3/8 port and mounting interface.
This double-acting cylinder uses a G3/8 air port and a 25 mm piston rod. It generates 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 force of 513 kgf at 1.0 MPa.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI80X95 replacement — usually within 7-8 hours.
