This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X430 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X430 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 SUD80X430
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X430 is a double-acting profile-type standard cylinder with a Ø80mm bore and 430mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X430, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X430
The AirTAC SUD80X430 is a double-acting, double-rod profile cylinder featuring a 80mm bore and 430mm stroke. Because a rod exits both ends on one piston, push and pull force are equal at 2268N @0.5 MPa, 3175N @0.7 MPa, and 4082N @0.9 MPa. This discontinued model used an extruded aluminium barrel with a 3/8" port, M20x1.5 rod thread, and 28mm adjustable cushions. The exact drop-in replacement is the SAUD80X430, matching the bore, stroke, force, and SC-series FA/LB mounting.
With 2268N of force at 0.5 MPa, the computed safe working load is roughly 1361N, allowing a vertical lift of about 116kg with a 2:1 margin. The double-rod design prevents piston rotation and lets the back rod carry a sensor cam. Since this SKU lacks a magnet, it cannot take a switch. Note that air cushions only decelerate the piston; an external rod lock is required to hold loads safely on air loss.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X430 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 SAUD80X430 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 SUD80X430 Is Used
Dual-Tool Transfer
Drives two synchronized clamps or pickers from opposite rod ends to grip and shift parts along an assembly line simultaneously.
Balanced Vertical Lift
Equal both-ways force raises and lowers a 116kg work platform smoothly without the gravitational asymmetry of a single-rod cylinder.
Anti-Rotation Indexing
The twin-rod geometry prevents piston twisting during the 430mm stroke, maintaining precise alignment for machining or pressing tasks.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X430 with the SAUD80X430
To replace the SUD80X430, install the drop-in SAUD80X430, which retains the 80mm bore, 430mm stroke, 3178N force, and FA/LB mounting. When sizing both ways, verify equal push/pull force against neighbouring bores (like the 63mm or 100mm) to meet your 2268N @0.5 MPa requirement. A double rod is ideal when you need anti-rotation or must drive two tools from one piston. If upgrading from a -S sensor model, note the change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors. For this 430mm stroke, add external guides to prevent rod bending under side loads. Remember, cushions only decelerate; use an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X430
- ✓ 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 SUD80X430 FAQ
Yes, the SUD80X430 is discontinued. The exact drop-in replacement is the SAUD80X430, which matches the 80mm bore, 430mm stroke, 3/8" port, and FA/LB mounting.
Force is equal both ways at 2268N @0.5 MPa, 3175N @0.7 MPa, and 4082N @0.9 MPa. The 80mm bore uses a 3/8" port, a 25mm rod, and 28mm adjustable cushions.
