This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X450S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X450S 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 SUD80X450S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X450S is a double-acting profile-type standard cylinder with a Ø80mm bore and 450mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X450S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X450S
The AirTAC SUD80X450S is a double-acting, double-rod profile cylinder featuring a 80mm bore and 450mm stroke. A rod exits both ends of the extruded aluminum barrel, meaning push and pull forces are equal both ways at 2268N @0.5MPa, 3175N @0.7MPa, and 4082N @0.9MPa. This discontinued model uses a 3/8 inch port, a M20x1.5 rod thread, and an adjustable 28mm cushion. The exact drop-in replacement is the SAUD80X450S, which retains the same body, mounting, and force.
Because the rear rod can drive a second tool or carry a sensor cam, the design offers excellent anti-rotation stability. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches, whereas the SAUD replacement uses current CMSG/DMSG/EMSG sensors. For sizing, the 2268N @0.5MPa force yields a safe working load of roughly 1361N, translating to a 116kg vertical lift with a 2:1 margin. Note that air cushions only decelerate near stroke end; an external rod lock is required for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X450S 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 SAUD80X450S 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.
Where the Airtac SUD Series Double Rod Cylinder SUD80X450S Is Used
Dual-Tool Machining
Drives two opposing machining heads simultaneously from a single piston, utilizing the equal both ways force for balanced material removal.
Anti-Rotation Transfer
Transfers heavy workpieces along a conveyor without rotational drift, relying on the twin rods to maintain strict parallel alignment.
Dual-End Pushing
Indexes parts from both ends of a sorting lane in alternating cycles, maximizing throughput in compact packaging cells.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X450S with the SAUD80X450S
To replace the discontinued SUD80X450S, order the drop-in SAUD80X450S, which matches the 80mm bore, 450mm stroke, 3/8 inch port, and FA/LB mounting. When sizing both ways, verify that the equal push/pull force of 2268N @0.5MPa is sufficient, or step to a neighboring bore. A double rod is right when you need anti-rotation stability or want to drive two tools from one piston. If upgrading, remember the -S sensor change from CS1-B/DS1-B to CMSG/DMSG/EMSG. Finally, for this 450mm stroke, add external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X450S
- ✓ 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 SUD80X450S FAQ
Yes, the SUD80X450S is discontinued. The exact drop-in replacement is the SAUD80X450S, which matches the 80mm bore, 450mm stroke, 3/8 inch port, and FA/LB mounting. You must upgrade 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. It outputs 2268N at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa. The 0.5MPa rating provides a safe working load of about 1361N, or a 116kg vertical lift with a 2:1 margin.
