The AirTAC Airtac SAU Standard Cylinders SAU100X50SNT is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 50mm stroke, 1/2" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.
SAU100X50SNT is a double-acting profile-type cylinder with a 100 mm bore and 50 mm stroke: air drives the 25 mm rod in both directions, and the extruded aluminium barrel keeps the overall length well below an ISO 15552 cylinder of the same bore - useful when every millimetre of machine envelope counts. At 0.5 MPa it pushes with 3927 N and pulls with 3681 N; at 0.7 MPa push force reaches 5497 N. The 1/2" air port (NPT thread on this T variant) and M20x1.5 rod-end thread are fixed by the bore, and the 29 mm adjustable cushions at each end tame end-of-stroke impact across the 30-800 mm/s speed range.
Because the code ends in SNT, this unit ships with a built-in piston magnet for CMSG, DMSG or EMSG switches, NBR seals and an NPT port. For planning: keep the real working load near 2356 N (about 60% of the 0.5 MPa push figure) to allow for seal friction and smooth travel, or expect roughly 200 kg of vertical lift with a 2:1 margin. If your process runs hot, the Viton H seal option stretches the temperature window from -20 to +70 C up to 0-150 C.

Related SAU-family variants: SAUD (double rod), SAUJ (adjustable stroke), SAUF (with built-in solenoid valve), and SAU-S with built-in magnet. Seals: TPU (blank) / Viton H / NBR N. Sensor switches: CMSG / DMSG / EMSG.
The 3927 N push at 0.5 MPa gives this 100 mm bore enough muscle to clamp steel castings in machining-centre fixtures, with the short 50 mm stroke suiting fast clamp-and-release cycles.
Pressing bearings or bushings into housings: 5497 N at 0.7 MPa covers light press work where a hydraulic press is overkill and the compact profile body saves valuable frame space.
Positioning heavy die segments on a stamping line - the short body fits tight die shoes, and the built-in magnet lets CMSG/DMSG/EMSG switches confirm die-in-place to the PLC.
Compare neighbours before committing: the 80 mm bore develops 2513 N push at 0.5 MPa, so if your load needs more than that, the 100 mm bore (3927 N at 0.5 MPa, 5497 N at 0.7 MPa) is the right step up - and it is the largest bore in the SAU range. Bear in mind that a plain cylinder cannot hold position: when air is lost or the valve centres, the piston drifts, and the air cushion only decelerates near stroke end - add an external rod lock or a pilot-operated check valve where a load must stay put. Mounting hardware is shared with the AirTAC SC series (LB foot, FA/FB flange, CA/CB clevis), and an I, Y, F or U rod knuckle suits the M20x1.5 thread.
Quick checklist
At 0.5 MPa it pushes with 3927 N and pulls with 3681 N; push force rises to 5497 N at 0.7 MPa and 7068 N at 0.9 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (proof 1.5 MPa), speed 30-800 mm/s, air port 1/2" NPT (the T option), rod 25 mm with M20x1.5 thread, and 29 mm adjustable cushions at both ends.
S means a piston magnet is built in, so CMSG, DMSG or EMSG switches can be snapped into the profile groove for end-of-stroke signalling - a SKU without the S cannot take a sensor. N specifies NBR seals (TPU is the standard, Viton H the high-temperature option up to 0-150 C), and T specifies an NPT port thread instead of the default PT.
