This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X300SH — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X300SH 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 SUD80X300SH 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 SAUD80X300SH, which matches its bore, stroke, force and mounting.
The AirTAC SUD80X300SH is a double-acting, double-rod profile cylinder featuring a 80mm bore, 300mm stroke, and a Viton H high-temperature seal (0 to 150 C). Because a rod exits both ends on one piston, push and pull force are equal at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. This discontinued model uses a 3/8 inch port, an M20x1.5 rod thread, and adjustable 28mm air cushions at each end. The exact drop-in replacement is the SAUD80X300SH, which retains the identical body, bore, stroke, force, and mounting.
The dual-rod design provides anti-rotation stability and allows the back rod to carry a sensor cam or drive a second tool simultaneously. With a 2268 N output at 0.5 MPa, the computed safe working load is roughly 1361 N, translating to a vertical lift capacity of about 116 kg with a 2:1 margin. This SUD variant includes a piston magnet for legacy CS1-B/DS1-B switches; upgrading to the SAUD requires switching to current CMSG/DMSG/EMSG sensors. Note that air cushions only decelerate the piston near stroke end and do not hold loads on air loss—an external rod lock is needed for held loads.

The SAUD80X300SH 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 forming tools simultaneously from a single piston, utilising the equal both ways force to ensure perfectly synchronised upstroke and downstroke movements.
Uses the twin-rod geometry to prevent mechanical twist during rapid part diversion on a packaging line, maintaining precise alignment without external guides.
Employs the rear rod as a sensor cam to confirm retraction in a hot end-of-line zone, relying on the Viton H seals for reliable 150 C operation.
To replace the discontinued SUD80X300SH, order the SAUD80X300SH drop-in equivalent, which maintains the exact 80mm bore, 300mm stroke, 3/8 inch port, and FA/LB mounting compatibility. When sizing both ways, verify the equal push/pull force fits your application, stepping to neighbouring bores if a higher or lower force is needed. A double-rod configuration is ideal when anti-rotation control is required or when the rear rod must drive a secondary mechanism. Because this unit has the -S magnet option, you must upgrade from the legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. For this 300mm stroke, external guides are recommended to prevent rod bending under side loads. The Viton H seal allows operation up to 150 C.
Replacement checklist
Yes, the SUD80X300SH is discontinued. The exact drop-in replacement is the SAUD80X300SH, which matches the 80mm bore, 300mm stroke, 3/8 inch port, and FA/LB mounting. You must upgrade the switches from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors.
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. The safe working load is approximately 1361 N, allowing a vertical lift of about 116 kg with a 2:1 safety margin.
