This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X75S in place of this model. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.

The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X75S is a double-acting profile-type standard cylinder with a Ø80mm bore and 75mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X75S, which matches its bore, stroke, force and mounting.
The AirTAC SUD80X75S is a discontinued double-acting double-rod profile cylinder. A rod exits both ends on one piston, meaning push and pull force are equal at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The exact drop-in replacement is the SAUD80X75S, matching the 80mm bore, 75mm stroke, 3/8" port, and mounting. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore.
The dual-rod design prevents rotation and lets the back rod carry a sensor cam for legacy CS1-B/DS1-B switches. Based on the 2268 N @0.5 MPa force, the safe working load is ~1361 N, allowing a vertical lift of ~116 kg with a 2:1 margin. Note that the air cushion only decelerates near stroke end; an external rod lock is required for load holding.

| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAUD80X75S produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

| ×75 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Drives two separate operations simultaneously using both rod ends, ensuring perfectly synchronized motion without adding a second cylinder.
The dual-rod geometry resists torsional twisting under offset loads, maintaining precise alignment for workpiece handling.
The rear rod extension provides a dedicated cam surface for mounting position switches without interfering with the primary work area.
To replace the SUD80X75S, use the SAUD80X75S drop-in, matching the bore, stroke, 3/8" port, and FA/LB mounting. The SAU replacement uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S magnet model. Size both ways by checking neighbor bores while verifying equal force both ways. A double rod is right when you need anti-rotation or must drive two tools. For stroke >=300, verify the side-load line. The cylinder does not hold loads without live air.
Replacement checklist
Yes, the SUD80X75S is discontinued. The exact drop-in replacement is the SAUD80X75S, which matches the 80mm bore, 75mm stroke, 3/8" port, and FA/LB mounting.
Force is equal both ways at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The air port is 3/8" with an M20x1.5 rod thread and 28mm adjustable cushions.
