This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32AX190, 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 SI32AX190 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 190mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI32AX190, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI32AX190 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 190mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. The direct replacement is the SAI32AX190, retaining identical mounting, force, and stroke.
This SKU lacks a magnet and cannot accept a sensor. The SAI upgrade features two Y-shaped piston seals for low start-up pressure. The -A code denotes a SUS420J2 stainless rod.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32AX190 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 SAI32AX190 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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 plastic or machined components out of a fixture with 402N force at 0.5MPa.
Provides a 190mm stroke to deflect small cartons on a conveyor line, operating at speeds up to 800mm/s.
Suitable for low-force clamping of delicate materials in automated assembly, using the SUS420J2 stainless rod.
To replace the SI32AX190, order the SAI32AX190. Verify the ISO 15552 interface, 190mm stroke, G1/8 port, and SUS420J2 rod. Since this SKU lacks -S, it cannot take a sensor; order a magnet-equipped SAI if CS1-B/DS1-B switches are needed. Neighbouring bores: SI40X190 gives 628N push @0.5MPa. Note: a plain cylinder drifts on air loss; use an external rod lock or SAIL/BSAI variant for load holding. At 190mm stroke, rod bending is minimal, but ensure guide alignment to prevent side-load wear.
Replacement checklist
Yes, the AirTAC SI32AX190 is discontinued. The direct replacement is the SAI32AX190. It shares the exact ISO 15552 mounting interface, 32mm bore, 190mm stroke, force, and G1/8 port, fitting existing fixtures perfectly.
This 32mm bore cylinder features a G1/8 port and M10x1.25 rod thread. Force ratings are: 402N push / 345N pull @0.5MPa, 563N push @0.7MPa, 724N push @0.9MPa, and a theoretical max of 82kgf @1.0MPa.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI32AX190 replacement — usually within 7-8 hours.
