This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X175S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X175S 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 SUD80X175S is a double-acting profile-type standard cylinder with a Ø80mm bore and 175mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X175S, which matches its bore, stroke, force and mounting.
The AirTAC SUD80X175S is a double-acting double-rod profile cylinder featuring a 25mm rod exiting both ends on one piston. This design ensures push and pull force are equal both ways, delivering 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore. This discontinued model uses a 3/8 port, M20x1.5 rod thread, and includes an -S piston magnet for legacy CS1-B/DS1-B switches.
The SUD80X175S is discontinued and the exact drop-in replacement is the SAUD80X175S, sharing the same bore, stroke, 3/8 port, and FA/LB mounting. The double-rod design provides anti-rotation stability and allows the back rod to carry a sensor cam. For sizing, the safe working load is roughly 1361 N (about 60% of the 2268 N at 0.5 MPa figure), yielding a vertical lift capacity of about 116 kg with a 2:1 margin. Note that air cushions only decelerate near stroke end; use an external rod lock for held loads.

The SAUD80X175S 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 with equal both ways force, utilizing the 2268 N at 0.5 MPa output for balanced material removal.
The double-rod construction prevents mechanical twist during rapid 30-800 mm/s sorting cycles, ensuring stable package diversion.
Lifts roughly 116 kg vertically with a 2:1 safety margin, using the back rod to carry a sensor cam for precise height confirmation.
To replace the discontinued SUD80X175S, specify the SAUD80X175S drop-in, which matches the 80mm bore, 175mm stroke, 3/8 port, and FA/LB mounting. When sizing both ways, verify the equal both ways force fits your load: neighbouring bores (63mm or 100mm) change the output, so the 80mm bore is critical if you need exactly 2268 N at 0.5 MPa. Choose a double rod when you need anti-rotation stability or must drive two tools simultaneously. For the -S magnet, change legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors on the SAUD. For this 175mm stroke (under 300mm), side-load alignment is standard, but always verify guide parallelism. A plain cylinder does not hold loads without live air; add a pilot-operated check valve or external rod lock if required.
Replacement checklist
Yes, the SUD80X175S is discontinued. The exact drop-in replacement is the SAUD80X175S, which matches the 80mm bore, 175mm stroke, 3/8 port, and FA/LB mounting. You must upgrade the -S magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG.
Because it is a double-rod cylinder, force is equal both ways: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The bore dictates a 3/8 port, it has a 25mm rod, M20x1.5 rod thread, and 28mm adjustable air cushions.
