This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X300 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X300 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 SUD80X300 is a double-acting profile-type standard cylinder with a Ø80mm bore and 300mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X300, which matches its bore, stroke, force and mounting.
The AirTAC SUD80X300 is a double-acting, double-rod profile cylinder featuring a 80mm bore and 300mm stroke. Because a rod exits both ends on one piston, push and pull force are equal at 2268N @0.5MPa, 3175N @0.7MPa, and 4082N @0.9MPa. This discontinued model uses an extruded aluminum profile barrel and a 3/8 inch air port. It is replaced by the drop-in SAUD80X300, which matches the bore, stroke, force, and mounting.
The SAUD80X300 upgrade retains the compact profile body and basic/FA/LB mounting but shifts to current CMSG/DMSG/EMSG sensors, whereas this legacy SUD used CS1-B/DS1-B switches. Note this specific SKU lacks a magnet and cannot take a sensor. For the 2268N @0.5MPa rating, the safe working load is roughly 1361N, yielding a vertical lift capacity of about 116kg with a 2:1 margin. A double rod prevents piston rotation and can drive two tools simultaneously.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X300 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| Max (@1.0 MPa) | 513 kgf | |
The SAUD80X300 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 machining heads simultaneously from one piston, ensuring perfectly synchronized cutting cycles without requiring a separate cylinder.
Uses the double-rod geometry to prevent piston rotation during extended 300mm transfers, maintaining precise alignment of workpieces on the conveyor line.
Applies equal clamping force from both ends of the fixture, securely holding irregular components in place during packaging or assembly operations.
To replace the SUD80X300, install the drop-in SAUD80X300; it preserves the 80mm bore, 300mm stroke, 3178N @0.7MPa equal-both-ways force, 3/8 inch port, and FA/LB mounting. When sizing both ways, verify the 2268N @0.5MPa output fits your load, or step to neighboring bores if higher force is needed. A double rod is right when you need anti-rotation, a back rod for a sensor cam, or dual-tool driving. If using a -S sensor, change from CS1-B/DS1-B to CMSG/DMSG/EMSG. Because this stroke is 300mm, add external guides to prevent rod bending under side loads. A plain cylinder drifts on air loss; use an external rod lock for held loads.
Replacement checklist
Yes, the SUD80X300 is discontinued. The exact drop-in replacement is the SAUD80X300, which matches the 80mm bore, 300mm stroke, equal both ways force, 3/8 inch port, and FA/LB mounting.
The 3/8 inch ported cylinder delivers equal push and pull force of 2268N @0.5MPa, 3175N @0.7MPa, and 4082N @0.9MPa. It uses a 25mm rod with M20x1.5 threads and adjustable 28mm cushions.
