The AirTAC Airtac SAI ISO Cylinders SAI63X100SG is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø63mm bore and 100mm stroke, G3/8 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 AirTAC SAI63X100SG is a double-acting ISO 15552 profile cylinder with a 63 mm bore, 100 mm stroke and G3/8 BSPP parallel ports that seal on a bonded face washer rather than on the thread - a clean, reusable connection favoured on European and Asian OEM plumbing. At 0.5 MPa it delivers 1559 N extend and 1402 N retract, enough for a compact press, gate or clamp travelling just 100 mm. Because the barrel is an extruded aluminium profile with magnet-piston (-S) built in, CMSE or DMSE reed switches snap into the grooves on both sides for end-of-stroke signalling without any bracket. Running hot washdown or near a heat source? Order the same cylinder with Viton H seals instead of standard TPU.

Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

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.
The 1559 N extend force at 0.5 MPa ejects sintered bronze bushings from a sizing die in one 100 mm hit, with 36 mm adjustable cushions softening the return.
A short 100 mm stroke is ideal for tucking top flaps at up to 800 mm/s cycle speed, while the on-board magnet and dual sensor grooves confirm each fold without extra brackets.
Swinging a kicker arm to push off-label bottles needs brisk, repeatable thrust; the G3/8 BSPP ports bond-seal onto the line's existing parallel-thread manifold.
Step down to the 50 mm bore if 982 N at 0.5 MPa covers your load; step up to the 80 mm bore (2513 N at 0.5 MPa) if you need headroom or plan to run below 0.5 MPa. Before ordering, match the port to your existing plumbing: this SG version has G3/8 BSPP parallel threads, so if your manifold and fittings are tapered PT/Rc, the plain SAI63X100S is the correct sibling. To swap an old ISO 15552 cylinder one-for-one, confirm four things: 63 mm bore, 100 mm stroke, G-series port thread, and the mounting accessory (LB foot, FA/FB flange, CA/CB clevis or TC trunnion). Note that a plain SAI cannot hold a load if air is lost - the piston will drift - so pick the SAIL rod-lock or BSAI clamp-lock variant for fail-safe holding.
Quick checklist
At 0.5 MPa it pushes with 1559 N and pulls with 1402 N; at 0.7 MPa push force rises to 2182 N, and at 0.9 MPa it reaches 2805 N. The theoretical maximum is 318 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa with a 1.5 MPa proof rating.
Yes, provided the port thread matches. This cylinder has G3/8 BSPP parallel ports that seal on a bonded washer; the interface dimensions (63 mm bore, 100 mm stroke, M16x1.5 rod thread) follow ISO 15552, so it interchanges with other ISO 15552 cylinders. If your machine uses tapered PT/Rc ports, order the plain SAI63X100S instead - same body, tapered plumbing.
