This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI32X190, 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 SI32X190 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 SAI32X190, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI32X190 is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 190mm stroke. It delivers 402N push and 345N pull at 0.5MPa through a G1/8 port. The direct replacement is the SAI32X190, retaining identical interface, force and mounting dimensions.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SKU lacks a magnet, so it cannot take a sensor. High-temp Viton H seals are available.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32X190 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 SAI32X190 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 machined components out of a fixture using the 402N force output.
Actuates a short 190mm stroke diverter arm to route small boxes on a material handling line.
Provides reliable clamping pressure for holding thin workpieces during secondary light machining.
To replace the SI32X190, order the SAI32X190 with the same ISO 15552 mounting interface, 190mm stroke, G1/8 port and M10x1.25 rod thread. Confirm your mounting accessory (LB, FA, TC) and thread standard (PT/G/NPT). As this SKU has no magnet (-S), you cannot fit CS1-B/DS1-B sensors; order an SAI32X190S if position sensing is needed. At 190mm stroke, side-load risk is low, but ensure guide alignment to prevent rod bending. The 32mm bore yields 402N at 0.5MPa; if more force is needed, step up to a 40mm bore (628N). For load holding on air loss, note the cushion only decelerates; use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
Yes, the SI32X190 is discontinued. The direct replacement is the SAI32X190, which shares the same ISO 15552 mounting interface, 32mm bore, 190mm stroke, output force and G1/8 port. It fits existing fixtures perfectly.
It features a G1/8 port and generates 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. Operating speed is 30-800mm/s.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI32X190 replacement — usually within 7-8 hours.
