This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD100X125S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD100X125S 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 SUD100X125S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD100X125S is a double-acting profile-type standard cylinder with a Ø100mm bore and 125mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD100X125S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD100X125S
The AirTAC SUD100X125S is a double-acting, double-rod profile cylinder featuring a 100mm bore, 125mm stroke, and a 1/2 inch port. Because a rod exits both ends on a single piston, the push and pull force is equal both ways at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. This model is discontinued. The exact drop-in replacement is the SAUD100X125S, which matches the bore, stroke, force, port, and FA/LB mounting.
The double-rod design prevents rotation and allows the back rod to carry a sensor cam for legacy CS1-B/DS1-B switches. The SAUD upgrade switches to current CMSG/DMSG/EMSG sensors and adds an SAUF built-in-valve variant. Based on the 3681 N @0.5 force, the safe working load is ~2209 N, yielding a vertical lift capacity of ~188 kg with a 2:1 margin. A plain cylinder does not hold loads on air loss; the 29mm cushion only decelerates, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD100X125S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUD100X125S 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 SUD100X125S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×125 | 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 SUD100X125S Is Used
Twin-Tool Driving
Drives two independent operations from one 100mm bore body, utilizing the equal both ways force to machine or form parts simultaneously from opposite sides.
Anti-Rotation Transfer
Moves pallets on a 1/2 inch port profile cylinder where the second rod prevents rotational drift, ensuring precise placement without external guides.
Symmetric Lift Station
Lifts ~188 kg vertical loads using the back rod as a sensor cam surface, maintaining stable elevation control in material handling.
Replacing the Airtac SUD Series Double Rod Cylinder SUD100X125S with the SAUD100X125S
To replace the discontinued SUD100X125S, order the SAUD100X125S drop-in. It preserves the 100mm bore, 125mm stroke, M20x1.5 rod thread, and 1/2 inch port. Size both ways by checking neighbor bores while confirming equal force both ways. Choose a double rod when you need anti-rotation or to drive two tools. Mounting is Basic, FA, or LB only. The -S magnet changes from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For stroke >=300, verify side-load line limits.
Replacement checklist
- ✓ Same bore / stroke → SAUD100X125S
- ✓ 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 SUD100X125S FAQ
