This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X50 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 SUD32X50
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X50 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 SAUD32X50, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X50
The AirTAC SUD32X50 is a double-acting, double-rod profile cylinder featuring a 32mm bore and 50mm stroke. Because a rod exits both ends, the push and pull forces are equal both ways at 345N @0.5 MPa. This discontinued model is directly replaced by the SAUD32X50, which retains the exact bore, stroke, 1/8" port, and FA/LB mounting compatibility. The compact extruded aluminum barrel is notably shorter than standard cylinders of the same bore.
With a 12mm rod and M10x1.25 thread, this unit provides adjustable 21mm cushions at each end. A key double-rod benefit is anti-rotation stability and the ability to drive two tools simultaneously. Based on the 345N @0.5 MPa rating, the computed safe working load is 207N (60%), translating to a vertical lift capacity of roughly 18kg with a 2:1 margin. Note this SKU lacks a magnet (-S) and cannot take sensors; the SAUD upgrade switches to CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X50 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 SAUD32X50 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 SUD32X50 Is Used
Dual-Tool Driving
Simultaneously actuates two opposing tooling heads with equal push and pull force, ensuring synchronized part processing.
Anti-Rotation Handling
Transfers lightweight components along a conveyor line where the twin rods prevent piston rotation and maintain precise alignment.
Compact Clamping
Fits into tight machinery envelopes to clamp workpieces, leveraging the short profile barrel to save space without losing force.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X50 with the SAUD32X50
To replace the discontinued SUD32X50, use the drop-in SAUD32X50 which matches the 32mm bore, 50mm stroke, and 1/8" port. When sizing both ways, verify your force needs against the 345N @0.5 MPa rating, or step up to the 40mm bore if higher force is required. Choose a double-rod cylinder when you need equal both-ways force or anti-rotation stability. Mounting is limited to Basic, FA, and LB (SC-series compatible only). Since this SKU has no magnet (-S), it cannot hold a sensor; the SAUD upgrade uses CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B. For strokes >=300mm, ensure your side-load limits are checked.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X50
- ✓ 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 SUD32X50 FAQ
Yes, the SUD32X50 is discontinued. The exact drop-in replacement is the SAUD32X50, which matches the 32mm bore, 50mm stroke, 1/8" port, and FA/LB mounting.
Force is equal both ways at 345N @0.5 MPa, 483N @0.7 MPa, and 621N @0.9 MPa. The cylinder does not hold loads on air loss; the 21mm cushion only decelerates near stroke end. Use an external rod lock for held loads.
