This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX800, 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 SI32 Standard Air Cylinder SI32AX800 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 800mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX800, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI32AX800 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 800mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. You must order the direct replacement SAI32AX800, which shares the exact ISO 15552 mounting interface, bore, stroke, output force, port and mounting accessories.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Since this SKU lacks a magnet, it cannot take a sensor (legacy types used CS1-B/DS1-B). The -A rod is SUS420J2 stainless.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32AX800 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 | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAI32AX800 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).
Ejects low-density parts from machining centers, relying on the SUS420J2 stainless rod for corrosion resistance.
To replace the SI32AX800, order the SAI32AX800. Confirm the ISO 15552 interface, 32mm bore, 800mm stroke, G1/8 port (PT/G/NPT thread options), SUS420J2 stainless rod, and mounting accessory. This SKU has no magnet, so it cannot accept a position switch. Sizing both ways: a 40mm bore gives 628N push at 0.5MPa, while dropping to a 25mm bore reduces force. Note that a plain cylinder drifts on air loss—the cushion only decelerates, so use an external rod lock or pilot check valve for holding. Because the 800mm stroke is long, use external guides to prevent rod bending and side-load wear. If you need an integrated lock or valve, explore the SAIL or BSAI variants.
Replacement checklist
Yes, the SI32AX800 is discontinued. The direct replacement is the SAI32AX800. It is dimensionally interchangeable per ISO 15552, matching the 32mm bore, 800mm stroke, 402N force, G1/8 port, and mounting fixtures.
This double-acting cylinder uses a G1/8 port. It generates 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical max of 82kgf at 1.0MPa.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI32AX800 replacement — usually within 7-8 hours.
