This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X300S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X300S 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 SUD32X300S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X300S is a double-acting profile-type standard cylinder with a Ø32mm bore and 300mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD32X300S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X300S
The AirTAC SUD32X300S is a double-acting, double-rod profile cylinder featuring a 32mm bore and 300mm stroke. A rod exits both ends on a single piston, meaning push and pull force is equal both ways at 345N @0.5MPa, 483N @0.7MPa, and 621N @0.9MPa. This model is discontinued; the exact drop-in replacement is the SAUD32X300S, retaining the same 1/8" port, M10x1.25 rod thread, and FA/LB mounting.
The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore. Because the rear rod can carry a sensor cam, it provides anti-rotation benefits and can drive two tools simultaneously. This SUD32X300S includes a piston magnet for legacy CS1-B/DS1-B switches, whereas the SAUD replacement uses current CMSG/DMSG/EMSG sensors. Based on the 345N @0.5MPa force, the computed safe working load is 207N, allowing a vertical lift of approximately 18kg with a 2:1 margin.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X300S 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 SAUD32X300S 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 SUD32X300S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×300 | 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 SUD32X300S Is Used
Dual-Tool Machining Station
Drives two opposing tools simultaneously from both rod ends, ensuring perfectly synchronized machining cycles without requiring a second actuator.
Anti-Rotation Transfer Pusher
Uses the dual-rod geometry to prevent piston rotation during horizontal part ejection on a conveyor, maintaining precise pusher alignment.
Compact Vertical Lifter
Lifts light fixtures vertically using the equal both ways force, fitting into tight machine envelopes where a longer ISO cylinder would not.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X300S with the SAUD32X300S
To replace this discontinued SUD32X300S, use the SAUD32X300S drop-in, which matches the 32mm bore, 300mm stroke, equal both ways force, and FA/LB mounting. When sizing both ways, verify the 345N @0.5MPa output fits your load, or step to a neighbour bore like 40mm (528N @0.5MPa) for more force. A double rod is right when you need anti-rotation or must drive two tools. For the -S sensor option, change legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG on the SAUD. Because the stroke is 300mm, add external guides to prevent rod bending and side-load damage. A plain cylinder does not hold loads on air loss; use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X300S
- ✓ 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 SUD32X300S FAQ
Yes, the SUD32X300S is discontinued. The exact drop-in replacement is the SAUD32X300S, which shares the same 32mm bore, 300mm stroke, 1/8" port, and FA/LB mounting. You only need to upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The double-rod design provides equal force both ways: 345N @0.5MPa, 483N @0.7MPa, and 621N @0.9MPa. It operates at 30-800mm/s, features a 1/8" port, and has a 21mm adjustable air cushion at each end.
