This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X80S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X80S 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 SUD32X80S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X80S is a double-acting profile-type standard cylinder with a Ø32mm bore and 80mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD32X80S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X80S
The AirTAC SUD32X80S is a double-acting, double-rod profile cylinder featuring a 32mm bore, 80mm stroke, and a 1/8" port. A rod exits both ends on a single piston, meaning both faces use the rod-side area and push/pull force is equal both ways (345N at 0.5MPa). This model is discontinued and the exact drop-in replacement is the SAUD32X80S, which retains the same body, bore, stroke, force, and FA/LB mounting.
Because the rear rod can carry a sensor cam or drive a second tool simultaneously, this double-rod design offers excellent anti-rotation stability. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches; upgrading to the SAUD requires current CMSG/DMSG/EMSG sensors. Based on the 345N force at 0.5MPa, the computed safe working load is roughly 207N, allowing a vertical lift of about 18kg with a 2:1 margin.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X80S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUD32X80S 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 SUD32X80S Is Used
Dual-Tool Machining
Drives two opposing tools simultaneously from a single piston, ensuring perfectly synchronized clamping and machining operations.
Anti-Rotation Transfer
Moves parts along a conveyor belt with high lateral stability, using the twin rods to prevent twisting during horizontal transfer.
Guided Ejection
Ejects finished components from a press straight and true, relying on the equal both-ways force and rigid double-rod guidance.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X80S with the SAUD32X80S
To replace the discontinued SUD32X80S, order the drop-in SAUD32X80S, which matches the 32mm bore, 80mm stroke, 1/8" port, and equal-both-ways force. When sizing both ways, verify your force needs against the 345N @0.5MPa rating, or step up to a neighbouring 40mm bore if higher thrust is required. Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools from one piston. Mounting is limited to Basic, FA, and LB styles (SC-series compatible only). For the -S sensor variant, note that the SAUD upgrade changes the switch compatibility from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG. For any stroke length of 300mm or greater, carefully manage side-load alignment to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X80S
- ✓ 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 SUD32X80S FAQ
Yes, the SUD32X80S is discontinued. The exact drop-in replacement is the SAUD32X80S, which matches the 32mm bore, 80mm stroke, 1/8" port, and equal-both-ways force. You will only need to upgrade the sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG models.
Because it is a double-rod cylinder, the push and pull force are equal both ways. The output is 345N at 0.5MPa, 483N at 0.7MPa, and 621N at 0.9MPa. A plain cylinder does not hold loads on air loss; the air cushion only decelerates near stroke end, so use an external rod lock for held loads.
