This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD100X80S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD100X80S 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 SUD100X80S is a double-acting profile-type standard cylinder with a Ø100mm bore and 80mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD100X80S, which matches its bore, stroke, force and mounting.
The AirTAC SUD100X80S is a double-acting, double-rod profile cylinder featuring a 100mm bore and 80mm stroke. A rod exits both ends on one piston, meaning both faces use the rod-side area and push and pull force are equal at 3681N @0.5MPa, 5153N @0.7MPa, and 6626N @0.9MPa. This SUD model is discontinued and end-of-life; the exact drop-in replacement is the SAUD100X80S, which matches the bore, stroke, force, 1/2 inch port, and SC-series FA/LB mounting. The SAUD upgrade uses current CMSG/DMSG/EMSG sensors and offers the SAUF built-in-valve variant the SU line lacked.
Because the rear rod can carry a sensor cam or drive a second tool simultaneously, this double-rod design provides excellent anti-rotation stability. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore. Based on the 3681N @0.5MPa rating, the computed safe working load is about 2209N, and the vertical lift capacity with a 2:1 margin is roughly 188kg. This unit has a built-in piston magnet for legacy CS1-B/DS1-B switches, a 25mm rod, M20x1.5 rod-end thread, and 29mm adjustable air cushions at each end. A plain cylinder does not hold its load on air loss; the cushion only decelerates near stroke end, so use an external rod lock for held loads.

The SAUD100X80S 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.

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 opposing tools simultaneously from one piston, utilising the equal both-ways force to machine parts on both ends of the 100mm bore cylinder.
Transfers heavy pallets on a conveyor line where the double-rod profile prevents rotational twist under high side-loading during rapid 30-800mm/s actuation.
Lifts a symmetric materials platform using the rear rod as a sensor cam carrier, ensuring precise positioning with the 29mm adjustable air cushions at each end.
To replace this discontinued SUD100X80S, order the drop-in SAUD100X80S, keeping the bore, stroke, magnet, and 1/2 inch port identical. When sizing both ways, verify the equal force fits your load; if you need less force, step down to the 80mm bore (2268N @0.5MPa), or if you need more, confirm if a larger custom bore is required. Choose a double-rod cylinder when you need anti-rotation stability, or when the back rod must carry a sensor cam or drive two tools. Mounting is limited to Basic, FA, and LB styles (SC-series compatibility only). Because this unit has the -S magnet, you must change from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors on the SAUD. For this 80mm stroke, side-load is minimal, but for any stroke >=300mm, ensure guide loads to prevent binding. Operating speed is 30-800mm/s.
Replacement checklist
Yes, the SUD100X80S is discontinued. The exact drop-in replacement is the SAUD100X80S, which matches the 100mm bore, 80mm stroke, 1/2 inch port, and FA/LB mounting. You must upgrade the sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
Force is equal both ways because both faces use the rod-side area. It outputs 3681N @0.5MPa, 5153N @0.7MPa, and 6626N @0.9MPa. The computed safe working load is about 2209N, yielding a vertical lift capacity of roughly 188kg with a 2:1 margin.
