This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD100X300S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD100X300S 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 SUD100X300S is a double-acting profile-type standard cylinder with a Ø100mm bore and 300mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD100X300S, which matches its bore, stroke, force and mounting.
The AirTAC SUD100X300S is a double-acting, double-rod profile cylinder where a rod exits both ends, yielding equal push and pull force of 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. This 100 mm bore, 300 mm stroke model is discontinued and replaced directly by the SAUD100X300S, retaining the 1/2 inch port, 29 mm cushions, and M20x1.5 rod thread.
Because both faces use the rod-side area, the back rod can drive a second tool or carry a sensor cam without losing thrust. The safe working load is roughly 2209 N, allowing a vertical lift of about 188 kg with a 2:1 margin. The legacy CS1-B/DS1-B sensors on this SUD model are superseded by CMSG/DMSG/EMSG switches on the SAUD. Note that air cushions only decelerate near stroke end; an external rod lock is required for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD100X300S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUD100X300S 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.
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | 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.
Drives two opposing tools simultaneously using both rod ends, maintaining equal 5153 N force at 0.7 MPa for balanced material removal.
Transfers workpieces on a conveyor using the back rod as an anti-rotation cam while the front rod executes the push stroke.
Lifts loads vertically up to 188 kg with a 2:1 safety margin, leveraging the equal both ways force to prevent gravity drift on the down stroke.
To replace the discontinued SUD100X300S, use the SAUD100X300S drop-in, which matches the 100 mm bore, 300 mm stroke, 1/2 inch port, and FA/LB mounting. Size both directions by checking equal force across neighbor bores, and migrate the -S magnet sensors from CS1-B/DS1-B to CMSG/DMSG/EMSG. For this 300 mm stroke, add external guides to prevent rod bending under side loads.
Replacement checklist
Yes, the SUD100X300S is discontinued. The exact drop-in replacement is the SAUD100X300S, which shares the same profile body, 100 mm bore, 300 mm stroke, 1/2 inch port, and FA/LB mounting.
The double-rod design yields equal force both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The 100 mm bore features a 1/2 inch port and 29 mm adjustable cushions.
