This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X30N, 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 SI32X30N is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 30mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32X30N, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI32X30N is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 30mm stroke. Delivering 402N push force at 0.5MPa via a G1/8 port, it is directly replaced by the SAI32X30N. This direct upgrade shares identical ISO 15552 mounting dimensions, bore, stroke, force and port, fitting existing fixtures perfectly.
The SAI replacement upgrades longevity with two Y-shaped one-way piston seals for low start-up pressure. This SKU lacks a magnet (-S) so cannot take a sensor, though legacy SI sensors were CS1-B/DS1-B. The NBR seal suits -20 to +70C; Viton H extends this to 150C.

| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAI32X30N 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 pushing lightweight finished parts out of a machining fixture using its 402N thrust at 0.5 MPa.
Provides reliable holding force for small workpieces in tight spaces where the 30mm stroke and G1/8 port fit neatly.
Actuates small pneumatic flaps or diverter gates in packaging lines, offering fast 30-800 mm/s cycling.
To replace the SI32X30N, order the SAI32X30N. Confirm the ISO 15552 mounting interface, 32mm bore, 30mm stroke, G1/8 port (PT/G/NPT thread) and your mounting accessory (LB, FA, TC, etc.). Because this SKU has no -S magnet, it cannot accept a magnetic switch; order a magnet-equipped SAI32X30NS if position sensing is required. The 32mm bore yields 402N push at 0.5MPa; sizing down is not an option, while sizing up to 40mm provides 628N. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external pilot check valve or explore SAIL/BSAI lock variants. At 30mm stroke, side-load risks are minimal, but ensure straight alignment.
Replacement checklist
Yes, the SI32X30N is discontinued. The direct replacement is the AirTAC SAI32X30N. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 30mm stroke, output force, G1/8 port and mounting interface.
The bore is 32mm with a G1/8 air port and M10x1.25 rod thread. Force ratings are: 402N push / 345N pull at 0.5 MPa, 563N push at 0.7 MPa, 724N push at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. Speed is 30-800 mm/s.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI32X30N replacement — usually within 7-8 hours.
