This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X80 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X80 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 SUD80X80 is a double-acting profile-type standard cylinder with a Ø80mm bore and 80mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X80, which matches its bore, stroke, force and mounting.
The AirTAC SUD80X80 is a double-acting, double-rod profile cylinder featuring an extruded aluminium barrel and a 3/8" port. Because a rod exits both ends on a single piston, the push and pull forces are equal at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. This SUD model is discontinued; the exact drop-in replacement is the SAUD80X80, which retains the same 80mm bore, 80mm stroke, M20x1.5 rod thread, and FA/LB mounting compatibility with the SC series.
The dual-rod design provides inherent anti-rotation stability and allows the rear rod to drive a secondary tool simultaneously. This non-magnet SKU cannot accept a switch, whereas the SAUD successor uses current CMSG/DMSG/EMSG sensors (the SUD used legacy CS1-B/DS1-B). For sizing, the 2268 N @0.5 MPa force yields a safe working load of roughly 1361 N, translating to a vertical lift capacity of about 116 kg with a 2:1 margin. Note that standard air cushions only decelerate the load near stroke end; an external rod lock is required for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X80 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAUD80X80 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.

| -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.
Uses the equal both-ways force to drive two forming tools simultaneously from opposite rod ends, ensuring perfectly balanced cycle timing.
The twin-rod architecture prevents mechanical twist during rapid part diversion across a packaging line, maintaining precise tracking.
Lifts components using the 2268 N @0.5 MPa force, safely managing a 116 kg vertical load with a 2:1 safety margin without drifting mid-stroke.
To replace the discontinued SUD80X80, install the drop-in SAUD80X80, which matches the 80mm bore, 80mm stroke, 3/8" port, and FA/LB mounting. Size both directions by checking neighbouring bores (63mm or 100mm) to guarantee the equal both-ways force fits your system. Choose a double-rod cylinder when your mechanism requires strict anti-rotation, needs the back rod to carry a sensor cam, or must drive two tools at once. If upgrading to the SAUD with the -S magnet option, switch from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For strokes >=300mm, verify the side-load limits to prevent guide bushing wear. Remember that air cushions only decelerate; add an external rod lock for load holding.
Replacement checklist
Yes, the SUD80X80 is discontinued. The exact drop-in replacement is the SAUD80X80, which matches the 80mm bore, stroke, 3/8" port, and FA/LB mounting.
Because it is a double-rod cylinder, force is equal both ways: 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The operating speed is 30-800 mm/s.
