This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X200SH, 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 SI80 Standard Air Cylinder SI80X200SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X200SH, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI80X200SH is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm stroke. Delivering 2513 N push and 2268 N pull at 0.5 MPa (4523 N at 0.9 MPa), it features a 25 mm rod, M20x1.5 thread, 36 mm cushions, and a G3/8 port. The direct replacement is the SAI80X200SH, matching the bore, stroke, force, port, and ISO 15552 mounting interface exactly.
This -SH configuration includes a piston magnet for legacy CS1-B/DS1-B sensors and a Viton H high-temperature seal (0-150 C). The SAI upgrade introduces a two-piece Y-shaped piston seal for low start-up pressure.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI80X200SH 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 | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAI80X200SH 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 applying consistent 2513 N clamping forces in automated assembly lines and pressing fixtures.
Provides robust actuation to push or lift heavy pallets, utilizing the 200 mm stroke for material routing.
To replace the SI80X200SH, order the SAI80X200SH. It is dimensionally interchangeable per ISO 15552, fitting existing fixtures without changes. Confirm your port thread (PT/G/NPT) and mounting accessory (LB, FA, TC, etc.). The -S magnet works with legacy CS1-B/DS1-B switches, though the SAI family uses current AirTAC sensors. The -H Viton seal handles 0-150 C environments. For sizing, neighbouring bores are 63 mm (1559 N push @0.5 MPa) and 100 mm (3927 N push). Note that a plain cylinder drifts on air loss; the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variants. At 200 mm stroke, rod bending is minimal, but guide external loads to prevent side-load wear.
Replacement checklist
Yes, the SI80X200SH is discontinued. The direct replacement is the SAI80X200SH. It shares the exact same ISO 15552 mounting interface, 80 mm bore, 200 mm stroke, output force, G3/8 port, and accessories, fitting directly into existing machinery.
The bore is 80 mm with a G3/8 air port. At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa push is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI80X200SH replacement — usually within 7-8 hours.
