This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX170, 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 SI32AX170 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 170mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX170, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI32AX170 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 170mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. AirTAC replaced this legacy unit with the SAI32AX170, a direct sharing the exact mounting interface, bore, stroke, force and port size.
Because this specific SKU lacks the -S suffix, it has no magnet and cannot accept a CS1-B/DS1-B sensor. The SAI upgrade features an improved piston seal with two Y-shaped one-way elements for low start-up pressure. The -A code denotes a SUS420J2 stainless steel rod for corrosion resistance.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32AX170 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 SAI32AX170 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).
Ideal for securing compact machined components during light milling or drilling operations where a 241N working load is sufficient.
Provides reliable actuation for lightweight package routing gates and sorting mechanisms in distribution centers.
Suitable for driving precise specimen movement or test fixture positioning in clean, controlled environments.
To replace the SI32AX170, order the SAI32AX170. Confirm the ISO 15552 interface, 32mm bore, 170mm stroke, G1/8 port, and SUS420J2 stainless rod. This no-magnet SKU cannot support sensing; if switches are needed, select an SAI equivalent with the S suffix. Since this is a 170mm stroke, ensure your guide handles side-loads to prevent rod bending. For sizing down, a 25mm bore offers less force; sizing up to 40mm yields 628N at 0.5MPa. Note that plain cylinders drift without live air—the cushion only decelerates. For load holding, use an external pilot check valve or explore the SAIL lock and BSAI clamp-lock variants.
Replacement checklist
Yes, the SI32AX170 is discontinued. The direct replacement is the SAI32AX170. It shares the identical ISO 15552 mounting interface, 32mm bore, 170mm stroke, force, and G1/8 port, fitting directly into existing fixtures.
This double-acting cylinder has a 32mm bore, M10x1.25 rod thread, 27mm cushion, and operates at 30-800 mm/s. Force ratings are: 402N push / 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a maximum theoretical force of 82kgf at 1.0MPa.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI32AX170 replacement — usually within 7-8 hours.
