This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD100X25 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD100X25 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.

The AirTAC Airtac SUD Series Double Rod Cylinder SUD100X25 is a double-acting profile-type standard cylinder with a Ø100mm bore and 25mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD100X25, which matches its bore, stroke, force and mounting.
The AirTAC SUD100X25 is a double-acting double-rod profile cylinder that is officially discontinued. The exact drop-in replacement is the SAUD100X25, matching the 100mm bore, 25mm stroke, 1/2 inch port, and Basic/FA/LB mounting. A rod exits both ends on one piston, meaning push and pull force are equal both ways at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa.
This SKU has no magnet (no -S) and cannot take a magnetic switch. A computed buyer insight from the 0.5 MPa rating gives a safe working load of about 2209 N, yielding a 188 kg vertical lift with a 2:1 margin. The double rod prevents rotation and drives two tools simultaneously. A plain cylinder does not hold loads on air loss; the 29 mm adjustable 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 SAUD100X25 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUD100X25 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.

| 100 | Bore size in mm. |
| ×25 | 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.
Drives two opposing machining heads simultaneously with equal force both ways, ensuring perfectly synchronized material removal.
Uses the double-rod geometry to prevent piston rotation during lateral product diversion on a high-speed packaging line.
Fits a shorter profile body than standard cylinders while providing 3681 N of push and pull force to eject heavy pallets.
To replace the discontinued SUD100X25, order the SAUD100X25 drop-in. Size both ways by checking neighbor bores (80mm or 63mm) against your equal-both-ways force needs. Choose a double rod when you need anti-rotation or to drive two tools. Mounting is Basic, FA, or LB only (AirTAC SC series compatible). Because this SKU lacks a magnet, you cannot use sensors; the SAUD upgrade uses current CMSG/DMSG/EMSG sensors instead of legacy CS1-B/DS1-B. For this 25mm stroke, side-load is minimal, but for strokes >=300mm ensure guide alignment.
Replacement checklist
Yes, the SUD100X25 is discontinued. The exact drop-in replacement is the SAUD100X25, which shares the same 100mm bore, 25mm stroke, 1/2 inch port, and Basic/FA/LB mounting.
Because it is a double-rod cylinder, force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The fixed air port size for the 100mm bore is 1/2 inch.
