The AirTAC Airtac SAU Standard Cylinders SAU50X100SNT is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 100mm stroke, 1/4" 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 SAU50X100SNT is a double-acting, profile-type AirTAC cylinder with a 50 mm bore and 100 mm stroke. Its extruded, hard-anodized aluminium barrel carries a sensor groove along the profile, and the whole body runs shorter than an ISO 15552 cylinder of the same bore - a genuine space saving when machine frames are tight. At 0.5 MPa it pushes 982 N and pulls 825 N, rising to 1374 N of push at 0.7 MPa. The 1/4" air port, 20 mm rod with M16x1.5 thread and 21 mm adjustable cushions at each end are all fixed by the bore, and travel speeds of 30-800 mm/s suit general automation.
Plan on roughly 589 N of usable work at 0.5 MPa - about 60% of the rated 982 N once seal friction and smooth-travel losses are deducted - which lifts about 50 kg vertically with a 2:1 margin. The -S suffix means a piston magnet is built in, so CMSG, DMSG or EMSG switches clip straight into the profile groove; the -N suffix specifies NBR seals (choose Viton H instead for a 0-150 C high-temperature version), and the -T option gives NPT threads on the 1/4" port in place of the default PT.

Clamping aluminium housings in a machining-centre fixture: 982 N of push at 0.5 MPa holds the part, and the 100 mm stroke retracts the clamp arm clear for robot loading.
Diverting cartons between conveyor lanes on a food-packaging line, where the ~589 N practical working load and adjustable cushions give a clean, non-slam push.
Pressing bushings into small pump housings at an assembly bench: bumping air to 0.7 MPa raises push force to 1374 N for light staking and insertion work.
Check the neighbours before committing: the 32 mm bore manages 402 N at 0.5 MPa for lighter pick-and-place duty, while the 63 mm bore reaches 1559 N for heavier clamping - this 50 mm model at 982 N sits between them for mid-weight tooling. Be aware the cylinder cannot hold a position on its own: with air lost or the valve centred the piston drifts, and the 21 mm end cushions only decelerate travel near stroke end, so fit an external rod lock or a pilot-operated check valve wherever a load must stay put. LB foot, FA/FB flange and CA/CB clevis mounts are shared with the AirTAC SC series, and an I, Y, F or U knuckle adapts the rod end to your linkage.
Quick checklist
At 0.5 MPa it pushes 982 N and pulls 825 N; at 0.7 MPa push force is 1374 N; at 0.9 MPa push reaches 1767 N. The theoretical maximum is 200 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa with a 1.5 MPa proof pressure, and rod speed runs 30-800 mm/s on this 50 mm bore.
S means a piston magnet is built in, enabling CMSG, DMSG or EMSG switches to sit in the profile groove for end-position sensing. N specifies NBR seals as standard (a Viton H option raises the temperature range to 0-150 C). T specifies NPT threads on the 1/4" air port instead of the default PT.
