This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1400SH, 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 SI80X1400SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1400mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X1400SH, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI80X1400SH is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel, delivering 2513 N push force at 0.5 MPa. It features a 1400 mm stroke, G3/8 port, M20x1.5 rod thread, and a high-temp Viton H seal rated for 0-150 C. The direct replacement is the SAI80X1400SH, sharing the same ISO 15552 mounting interface, bore, stroke, force, and port for seamless fixture integration.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. The SAI family also adds SAIL lock, BSAI clamp-lock, and SAIF valve variants unavailable in the SI line. Your -S magnet supports legacy CS1-B/DS1-B sensors, while the SAI uses current AirTAC switches.

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).
Drives large package pushers across wide conveyor belts, utilizing the 1400 mm reach to sort heavy pallets without intermediate transfers.
Extracts totes from deep shelving racks, where the 2513 N push force handles loaded containers and the Viton H seal withstands warm warehouse ceilings.
Feeds heavy sheet metal blanks into forming presses, requiring external guides to support the extended rod over the 1400 mm span.
To replace the SI80X1400SH, order the SAI80X1400SH direct, confirming the ISO 15552 interface, 80 mm bore, 1400 mm stroke, G3/8 port, and mounting accessory. The -S magnet and -H Viton high-temp seal carry over directly. For load sizing, a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N; this 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, peaking at 513 kgf at 1.0 MPa. Because the 1400 mm stroke is long, use external guides to prevent rod bending and side-load wear. A plain cylinder does not hold load without live air; for drop protection, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
Yes, the SI80X1400SH is discontinued. The direct replacement is the SAI80X1400SH. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the same 80 mm bore, 1400 mm stroke, output force, G3/8 port, and mounting fixtures.
This double-acting cylinder features a G3/8 air port and provides 2513 N push and 2268 N pull at 0.5 MPa. At 0.7 MPa push is 3518 N, at 0.9 MPa it is 4523 N, and the theoretical max force is 513 kgf at 1.0 MPa. It operates at 30-800 mm/s with a 36 mm adjustable cushion.
