This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X25S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X25S 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 SUD32X25S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X25S is a double-acting profile-type standard cylinder with a Ø32mm bore and 25mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD32X25S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X25S
The AirTAC SUD32X25S is a double-acting, double-rod profile cylinder featuring an extruded aluminium barrel and a 1/8 inch port. Because a rod exits both ends on one piston, both faces use the rod-side area, making push and pull force equal at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. This SUD model is discontinued and the exact drop-in replacement is the SAUD32X25S, which retains 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 upgrades to CMSG/DMSG/EMSG sensors). For sizing, the 345 N @0.5 MPa output yields a safe working load of about 207 N and a vertical lift capacity of roughly 18 kg with a 2:1 margin. A plain cylinder does not hold loads on air loss; the 21 mm adjustable cushions only decelerate near stroke end, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X25S 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 SAUD32X25S 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.

| -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 SUD32X25S Is Used
Dual-Tool Pick & Place
Drives two opposing grippers simultaneously from one compact 32 mm bore body, ensuring perfectly synchronized part transfer without adding a second actuator.
Anti-Rotation Indexing
The twin-rod geometry resists torsional twist during horizontal pushing tasks, maintaining precise alignment for small component seating operations.
Symmetric Ejector Gate
Uses the equal both ways force to reliably push rejected parts off a belt in one direction and retract the gate with the same authority on the return stroke.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X25S with the SAUD32X25S
To replace the discontinued SUD32X25S, specify the SAUD32X25S drop-in, ensuring the bore, stroke, 1/8 inch port, and FA/LB mounting remain identical. When sizing both ways, verify your force needs against the equal both ways output (345 N @0.5 MPa, 483 N @0.7 MPa, 621 N @0.9 MPa) and check neighbouring bores if a higher margin is required. Choose a double rod when you need anti-rotation stability or want to drive two tools simultaneously. For the -S magnet option, note the sensor change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG. For stroke lengths of 300 mm or more, confirm the side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X25S
- ✓ 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 SUD32X25S FAQ
Yes, the SUD32X25S is discontinued. The exact drop-in replacement is the SAUD32X25S, which matches the 32 mm bore, 25 mm stroke, 1/8 inch port, and FA/LB mounting. You will need to upgrade the piston magnet sensors from legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG series.
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. It operates at speeds between 30 and 800 mm/s, uses a 12 mm rod with an M10x1.25 thread, and features 21 mm adjustable air cushions at each end.
