The AirTAC Airtac SAI ISO Cylinders SAI32X80SG is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 80mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The SAI32X80SG is a genuine AirTAC double-acting profile cylinder built to the ISO 15552 mounting interface, with G1/8 BSPP parallel ports in place of the standard tapered PT thread. These parallel ports seal on a bonded face washer rather than on the thread itself, so they mate cleanly with EU-style OEM manifold blocks and reusable bonded-seal fittings. Bore 32 output reaches about 402 N pushing at 0.5 MPa, and the 80 mm stroke suits short, repetitive work moves on compact machinery. The trailing S in the model code means a piston magnet is already fitted, so CMSE or DMSE reed/hall switches can be clipped straight into the sensor groove machined along both sides of the extruded aluminum barrel - no end-position mechanical stops needed. Rod options are carbon steel as standard, or SUS420J2 (A) / SUS304 (B) stainless where wash-down or corrosion resistance matters.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Pushes rejected components off pick-and-place feeder rails in electronics assembly; 402 N at 0.5 MPa clears small parts instantly, while the 80 mm stroke matches tight feeder-pitch spacing and the fitted magnet feeds cycle-complete signals to the PLC.
Applies the light pressing action needed to seat pump caps and overcaps on 30-50 ml skincare bottles; the 345 N pull force at 0.5 MPa also retracts the press head briskly for high cycle rates on a rotary filling line.
Diverts underweight small cartons off a food-packaging conveyor between checkweigher and case packer; the G1/8 BSPP ports connect directly to European valve manifolds, and the double-side sensor groove allows extend and retract position flags on one cylinder.
Bore 32 is the smallest SAI size, so there is nothing to step down to - if 402 N at 0.5 MPa is marginal for your load, go one bore up to the SAI40, which delivers 628 N pushing at the same pressure. Size the bore so working force covers the load with roughly 30-50% margin, and remember the plain SAI offers no position holding: if supply air fails or the valve centres, the piston drifts, so specify the SAIL rod-lock or BSAI clamp-lock variant for fail-safe loads. For a like-for-like ISO 15552 replacement, match four things: 32 mm bore, 80 mm stroke, G1/8 BSPP ports (confirm your existing fittings are parallel-thread, since the standard SAI uses tapered PT), and the mounting accessory (LB foot, FA/FB flange, CA/CB clevis or TC trunnion). The magnet fitted here means proximity sensing carries over without reordering.
Quick checklist
At 0.5 MPa it pushes with 402 N and pulls with 345 N; at 0.7 MPa pushing force rises to 563 N, and at 0.9 MPa to 724 N. The theoretical maximum at 1.0 MPa is about 82 kgf. Operating pressure range is 0.15-1.0 MPa with 1.5 MPa proof pressure, and the 27 mm adjustable cushions at both ends decelerate the piston near stroke end.
Yes - the SAI conforms to the ISO 15552 mounting interface, so it is dimensionally interchangeable with other ISO 15552 profile cylinders when bore (32 mm), stroke (80 mm), port thread and mounting accessory match. The trailing G means G1/8 BSPP parallel ports, which seal on a bonded washer and are common on European OEM plumbing; if your machine has tapered fittings, order the plain-thread version instead. Because the magnet is fitted, CMSE/DMSE switches work out of the box.
