This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X250S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X250S 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 SUD32X250S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X250S is a double-acting profile-type standard cylinder with a Ø32mm bore and 250mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD32X250S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X250S
The AirTAC SUD32X250S is a discontinued double-acting double-rod profile cylinder featuring a 32mm bore, 250mm stroke, and a 1/8" port. Because a rod exits both ends on a single piston, both faces use the rod-side area, meaning push and pull force are equal at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore. This model is end-of-life; the exact drop-in replacement is the SAUD32X250S, sharing the same bore, stroke, force, port, and FA/LB mounting.
The double-rod design provides anti-rotation stability and allows the back rod to carry a sensor cam for legacy CS1-B/DS1-B switches (the SAUD replacement uses current CMSG/DMSG/EMSG sensors). For sizing, the 345 N @0.5 MPa force yields a safe working load of ~207 N (60% factor) and a vertical lift capacity of ~18 kg with a 2:1 margin. A plain cylinder does not hold loads on air loss—the cushion only decelerates near stroke end—so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X250S 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 SAUD32X250S 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.

| 32 | Bore size in mm. |
| ×250 | 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 SUD32X250S Is Used
Gripping Transfer Arms
Drives dual-sided pick-and-place arms where equal push/pull force and anti-rotation stability are required to grip and transfer components precisely.
Dual-Tool Diverters
Simultaneously actuates two diverting mechanisms across a conveyor using both rod ends, ensuring perfectly synchronized material routing.
Compact Vertical Lifts
Performs short-stroke vertical lifting in tight warehouse machinery cells where the shorter profile barrel saves axial space.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X250S with the SAUD32X250S
To replace the SUD32X250S, install the drop-in SAUD32X250S, which matches the 32mm bore, 250mm stroke, 1/8" port, and FA/LB mounting. When sizing both ways, verify the 345 N @0.5 MPa equal-both-ways force is sufficient, or step to the neighbouring 40mm bore. Choose a double-rod cylinder when anti-rotation stability or driving two tools simultaneously is required. Note the -S sensor change from CS1-B/DS1-B to CMSG/DMSG/EMSG. For this 250mm stroke (which is under 300mm), side-load alignment is standard, but always ensure rigid FA/LB mounting.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X250S
- ✓ 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 SUD32X250S FAQ
Yes, the SUD32X250S is discontinued. The exact drop-in replacement is the SAUD32X250S, which matches the 32mm bore, 250mm stroke, 1/8" port, and FA/LB mounting. You must upgrade switches from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.
Because it is a double-rod cylinder, force is equal both ways: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. Operating speed is 30-800 mm/s. The safe working load is ~207 N, allowing a vertical lift of ~18 kg with a 2:1 margin.
