This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X60SN, 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 SI80X60SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 60mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X60SN, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI80X60SN is a discontinued double-acting ISO 15552 profile cylinder. It delivers 2513 N of push force at 0.5 MPa through an 80 mm bore and features a G3/8 air port. AirTAC replaced this legacy unit with the SAI80X60SN, a direct replacement retaining the exact same interface, 60 mm stroke, output force, and mounting accessories.
The SAI upgrade introduces a refined piston seal utilizing two Y-shaped one-way elements for extended lifespan and lower start-up pressure. This -SN variant includes a piston magnet for CS1-B/DS1-B legacy sensors and uses NBR seals rated for -20 to +70 C (a Viton H option extends this to 150 C).

The SAI80X60SN 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).
Applies the 2513 N push force at 0.5 MPa for seating bearings, stamping light sheet metal, or clinching components in automated assembly lines.
Executes 60 mm strokes to actuate routing gates or pusher arms, redirecting heavy cartons up to 128 kg off a main conveyor belt.
Drives short-stroke lifting mechanisms for pallet stops and transfer sections, utilizing the robust 25 mm piston rod to absorb side impacts.
To replace the SI80X60SN, order the SAI80X60SN. Verify your ISO 15552 mounting fixture, the G3/8 port thread (PT/G/NPT), and the M20x1.5 rod-end connection. The integrated magnet (-S) allows for legacy CS1-B/DS1-B switches, though the SAI replacement family utilizes current AirTAC sensors. When sizing, note the 80 mm bore yields 2513 N push and 2268 N pull at 0.5 MPa; dropping to a 63 mm bore reduces push to 1559 N, while an 80 mm bore at 0.7 MPa increases push to 3518 N. Remember that a standard cylinder drifts without live air; the adjustable 36 mm cushions only decelerate near stroke end. For secure load holding, consider an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
Yes, the AirTAC SI80X60SN is discontinued and end-of-life. The direct replacement is the SAI80X60SN. It is dimensionally interchangeable per ISO 15552, offering the exact same 80 mm bore, 60 mm stroke, force, G3/8 port, and mounting interface.
The bore is 80 mm with a G3/8 air port. Force output is 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N push at 0.9 MPa. 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 SAI80X60SN replacement — usually within 7-8 hours.
