This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X125S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X125S 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 SUD32X125S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X125S is a double-acting profile-type standard cylinder with a Ø32mm bore and 125mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD32X125S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X125S
The AirTAC SUD32X125S is a discontinued double-acting double-rod profile cylinder featuring a 32mm bore, 125mm stroke, and 1/8" port. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal both ways at 345 N @0.5 MPa. The exact drop-in replacement is the SAUD32X125S, retaining the same body, bore, stroke, force, and FA/LB mounting. The SAU upgrade uses current CMSG/DMSG/EMSG sensors instead of this model's legacy CS1-B/DS1-B switches, and offers an SAUF built-in-valve variant.
Because the rear rod carries a sensor cam and drives two tools, it provides anti-rotation benefits without external guides. Based on the 345 N @0.5 MPa force, the computed safe working load is ~207 N (60% of rated force), yielding a vertical lift capacity of ~18 kg with a 2:1 margin. The adjustable 21mm air cushion only decelerates near stroke end; it does not hold loads on air loss, requiring an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X125S 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 SAUD32X125S 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 SUD32X125S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | 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 SUD32X125S Is Used
Dual-Tool Driving
Drives two synchronized tools from opposite rod ends, ensuring equal force both ways for matched opposing operations.
Anti-Rotation Handling
The dual-rod geometry prevents piston rotation during travel, ideal for precise pick-and-place handling without external guides.
Compact Transfer
Fits tight transfer stations where a shorter profile barrel is needed compared to standard cylinders of the same bore.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X125S with the SAUD32X125S
To replace the discontinued SUD32X125S, specify the drop-in SAUD32X125S, which matches the 32mm bore, 125mm stroke, 1/8" port, and FA/LB mounting. Size both ways by checking neighbor bores while verifying the equal both-ways force fits your application. A double rod is right when you need anti-rotation or must drive two tools simultaneously. For the -S magnet option, change legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG on the SAU. For this 125mm stroke (under 300mm), side-load alignment is straightforward, but always keep the load centered. Mounting is compatible with the AirTAC SC series only.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X125S
- ✓ 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 SUD32X125S FAQ
Yes, the SUD32X125S is discontinued. The exact drop-in replacement is the SAUD32X125S, which shares the same 32mm bore, 125mm stroke, 1/8" port, and FA/LB mounting. You only need to upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The SUD32X125S provides equal force both ways: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. It operates at speeds of 30-800 mm/s, features a 12mm rod, M10x1.25 rod thread, and a 21mm adjustable air cushion at each end.
