This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X80S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X80S 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.
Airtac SUD Series Double Rod Cylinder SUD80X80S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X80S is a double-acting profile-type standard cylinder with a Ø80mm bore and 80mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X80S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X80S
The AirTAC SUD80X80S is a double-acting, double-rod profile cylinder featuring an extruded aluminium barrel and a 3/8" port. Because a rod exits both ends on one piston, both faces use the rod-side area, meaning push and pull force are equal at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. This SUD model is discontinued and the exact drop-in replacement is the SAUD80X80S, which retains the same bore, stroke, force, port, and FA/LB mounting.
The double-rod design prevents piston rotation and allows the back rod to carry a sensor cam or drive a second tool simultaneously. With a 2268 N force at 0.5 MPa, the safe working load is roughly 1361 N, yielding a vertical lift capacity of about 116 kg with a 2:1 margin. This unit includes a piston magnet for legacy CS1-B/DS1-B switches; upgrading to the SAUD requires current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X80S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAUD80X80S 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.
Model Code: Airtac SUD Series Double Rod Cylinder SUD80X80S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 80 | Bore size in mm. |
| ×80 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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.
Where the Airtac SUD Series Double Rod Cylinder SUD80X80S Is Used
Dual-Tool Machining
Drives two opposing tools simultaneously from a single piston, ensuring perfectly synchronized strokes without requiring a separate cylinder.
Anti-Rotation Transfer
Moves parts across a conveyor belt with high lateral stability, using the second rod to prevent piston twisting under offset loads.
Symmetric Push-Pull Sorting
Provides equal push and pull force to shuttle products into bins from either direction without losing thrust capacity.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X80S with the SAUD80X80S
To replace the discontinued SUD80X80S, select the SAUD80X80S drop-in, matching the 80mm bore, 80mm stroke, 3/8" port, and FA/LB mounting. Size both ways by checking neighbour bores while confirming equal force in both directions. Choose a double-rod cylinder when anti-rotation or dual-tool driving is required. For the -S sensor option, change legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG. For strokes >=300, verify side-load limits. A plain cylinder does not hold loads on air loss; the cushion only decelerates, so use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X80S
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SUD Series Double Rod Cylinder SUD80X80S FAQ
Yes, the SUD80X80S is discontinued. The exact drop-in replacement is the SAUD80X80S, which matches the bore, stroke, force, and port. You must upgrade the sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG.
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. It operates at speeds of 30-800 mm/s with a 3/8" port.
