This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X50S 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 SUD32X50S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X50S is a double-acting profile-type standard cylinder with a Ø32mm bore and 50mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD32X50S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X50S
The AirTAC SUD32X50S is a discontinued double-acting double-rod profile cylinder. A rod exits both ends on one piston, meaning both faces use the rod-side area and push and pull force are equal at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The exact drop-in replacement is the SAUD32X50S, sharing the same 32mm bore, 50mm stroke, 1/8" port, and SC-series FA/LB mounting. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore.
This model features a built-in piston magnet (-S) for legacy CS1-B/DS1-B switches, whereas the SAUD replacement uses current CMSG/DMSG/EMSG sensors. The double-rod design provides anti-rotation stability and allows the back rod to carry a sensor cam. For sizing, the safe working load is roughly 207 N (60% of the 345 N @0.5 MPa figure), yielding a vertical lift capacity of about 18 kg with a 2:1 margin. It has a 12mm rod, M10x1.25 rod-end thread, 21mm adjustable cushions, and operates at 30-800 mm/s.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X50S 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 SAUD32X50S 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.

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 SUD32X50S Is Used
Dual-Tool Driving
Drives two independent mechanisms simultaneously using both rod ends, ensuring perfectly synchronized motion without adding a second cylinder.
Anti-Rotation Guidance
The dual-rod architecture prevents piston rotation during extension and retraction, ideal for parts handling requiring strict angular orientation.
Cam-Driven Sensing
The rear protruding rod carries a sensor cam, allowing position switches to be mounted on the back face to save valuable front-end tooling space.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X50S with the SAUD32X50S
To replace the discontinued SUD32X50S, use the drop-in SAUD32X50S, which matches the 32mm bore, 50mm stroke, 1/8" port, and FA/LB mounting. When sizing both ways, verify force needs against neighboring bores; the 40mm bore offers higher force, while smaller bores offer less. A double rod is right when you need anti-rotation stability or want to drive two tools simultaneously. Note the -S sensor change from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG. For stroke lengths >=300mm, account for side-load line limits. A plain cylinder does not hold loads on air loss; the cushion only decelerates near stroke end, so use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X50S
- ✓ 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 SUD32X50S FAQ
Yes, the SUD32X50S is discontinued. The exact drop-in replacement is the SAUD32X50S. It matches the 32mm bore, 50mm stroke, 1/8" port, and FA/LB mounting, but uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
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. The air port is 1/8" PT, the rod is 12mm with an M10x1.25 thread, and speed is 30-800 mm/s.
