This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the drop-in replacement SAI32BX700, 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 Airtac SI32 Standard Air Cylinder SI32BX700 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 700mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAI32BX700, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI32BX700 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 700mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. The direct drop-in replacement is the SAI32BX700, matching the interface, stroke, force and mounting exactly.
This SKU features a SUS304 stainless steel rod (B option) and lacks a magnet, so it cannot accept a CS1-B/DS1-B sensor. The SAI upgrade utilizes two Y-shaped piston seals for low start-up pressure. For sizing, a safe working load is ~241N, yielding a ~20kg vertical lift capacity with a 2:1 margin.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32BX700 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|

| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAI32BX700 produces the same force from the same bore — a true drop-in on output. 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).
Uses the 402N push force at 0.5MPa to eject small molded components reliably without damaging the product surface.
The 700mm stroke extends across a narrow belt to divert light cardboard boxes into secondary packaging lanes.
Raises lightweight 20kg tote bins vertically using the full 700mm travel, safely staying within the 2:1 load margin.
To replace this SI32BX700, order the SAI32BX700. Confirm the ISO 15552 mounting interface, 32mm bore, 700mm stroke, G1/8 port and specific mounting accessory. This non-magnet SKU cannot support sensing; if needed, order an SAI with the S suffix for CS1-B/DS1-B switches. Because this is a 700mm stroke, add external guides to prevent rod bending and side-loads. A plain cylinder drifts on air loss; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. If more force is needed, the neighboring 40mm bore provides 628N push at 0.5MPa.
Replacement checklist
Yes, the SI32BX700 is discontinued. The exact drop-in replacement is the SAI32BX700. It is dimensionally interchangeable per ISO 15552, matching the 32mm bore, 700mm stroke, force, G1/8 port and mounting interface.
It has a G1/8 port. Force ratings are 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 SAI32BX700 replacement — usually within 7-8 hours.
