The AirTAC Airtac SAU Standard Cylinders SAU80X150T is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 150mm stroke, 3/8" 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.
The AirTAC SAU80X150T is a double-acting profile-type cylinder with NPT 3/8 in tapered ports that seal on the thread itself - the North-American pipe standard, chosen by ordering this T variant instead of the default PT version. Its extruded, hard-anodized aluminum barrel carries a sensor groove and adjustable cushions at both ends, and it is shorter than an ISO 15552 cylinder of the same 80 mm bore, so it frees length in a tight machine frame. At 0.5 MPa this bore pushes 2513 N and pulls 2268 N; at 0.9 MPa it reaches 4523 N. Budget roughly 1508 N (0.6 x 2513) of useful work at 0.5 MPa for seal friction and smooth travel, or expect a 2:1-margin vertical lift of about 128 kg (2513 N / 9.81, halved). Standard TPU seals suit most air lines, while the Viton H option extends temperature to 0-150 C; the 28 mm cushions slow the piston near each end of the 150 mm stroke, and rod speed stays anywhere in the 30-800 mm/s window.

Clamps heavy steel workholding fixtures on a machining centre table: 2513 N at 0.5 MPa holds the part through cut cycles, with the 150 mm stroke clearing chip management space.
Ejects filled cartons from a forming station at up to 800 mm/s; the shorter-than-ISO 15552 body slots into crowded packaging frames, and NPT ports match North-American plant plumbing.
Raises a palletizer divert gate weighing up to about 128 kg with a 2:1 vertical-lift margin, using adjustable cushions to settle the gate without metal-to-metal stops.
Compare neighbours before committing: the SAU63X150T gives 1559 N at 0.5 MPa if this 80 mm bore is oversized, while the SAU100X150T delivers 3927 N when you need more. Match the NPT ports to your existing North-American fittings and manifold - they are tapered and seal on the thread, so do not swap in G (BSPP) parallel hardware with bonded washers. Because the rod drifts whenever air is exhausted or the valve centres, add an external rod lock or pilot-operated check valve for any held load. Position sensing needs the -S magnet option for CMSG, DMSG or EMSG switches; mounting follows the SC series with LB foot, FA/FB flange and CA/CB clevis plus I, Y, F or U knuckles.
Quick checklist
Push 2513 N and pull 2268 N at 0.5 MPa, push 3518 N at 0.7 MPa, and 513 kgf theoretical at 1.0 MPa. The 80 mm bore has a 25 mm chrome rod (M20x1.5 thread), NPT 3/8 in tapered ports, 28 mm adjustable cushions, 0.15-1.0 MPa working pressure and a 30-800 mm/s speed range.
The trailing T orders NPT tapered ports that seal on the thread - standard for North-American fittings - whereas the blank SKU uses PT and the G suffix uses BSPP parallel ports with a bonded washer; pick whichever matches your manifold. Yes, switches work: order the -S magnet variant and CMSG, DMSG or EMSG switches clip into the profile groove. Mounting hardware is shared with the AirTAC SC series (LB, FA/FB, CA/CB).
