This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X260S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X260S 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 SUD80X260S is a double-acting profile-type standard cylinder with a Ø80mm bore and 260mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X260S, which matches its bore, stroke, force and mounting.
The AirTAC SUD80X260S is a double-acting, double-rod profile cylinder featuring a 80mm bore and 260mm stroke. A rod exits both ends on a single piston, meaning push and pull force are equal both ways at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. This discontinued model uses an extruded aluminum profile barrel and a 3/8 inch port. The exact drop-in replacement is the SAUD80X260S, sharing the same body, bore, stroke, force, port, and FA/LB mounting.
With a 25mm rod and M20x1.5 thread, the back rod can drive a second tool or carry a sensor cam for anti-rotation guidance. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B switches; the SAUD upgrade uses current CMSG/DMSG/EMSG sensors. Based on the 2268 N @0.5 MPa rating, the safe working load is roughly 1361 N, yielding a vertical lift capacity of about 116 kg with a 2:1 margin. Note that air cushions only decelerate the piston; an external rod lock is required for load holding.

The SAUD80X260S 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 using both rod ends, ensuring perfectly synchronized part processing without requiring a second cylinder.
The twin-rod geometry prevents the piston from twisting during rapid lateral pushing of heavy workpieces across a conveyor belt.
Lifts and lowers a balanced materials jig with equal force both ways, keeping the payload stable throughout the vertical travel range.
To replace the discontinued SUD80X260S, specify the SAUD80X260S drop-in, which preserves the 80mm bore, 260mm stroke, 3178 inch port, and FA/LB mounting. When sizing both ways, verify your force needs against the equal both ways ratings (2268 N @0.5, 3175 N @0.7, 4082 N @0.9) and check neighbouring bores if you need a higher or lower capacity. Choose a double-rod design when you need anti-rotation stability or must drive two tools from one cylinder. For the -S magnet option, note that the SAUD requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. Because the 260mm stroke exceeds 300mm, ensure your side-load limits are adequate to prevent guide wear.
Replacement checklist
Yes, the SUD80X260S is discontinued. The exact drop-in replacement is the SAUD80X260S, which matches the 80mm bore, 260mm stroke, equal both ways force, 3/8 inch port, and FA/LB mounting. You only need to update the sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
Because it is a double-rod cylinder, the force is equal both ways: 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The bore dictates a fixed 3/8 inch port. The air cushions only decelerate the load near stroke end; they do not hold the load on air loss, so use an external rod lock for holding.
