This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X350 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X350 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 SUD32X350
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X350 is a double-acting profile-type standard cylinder with a Ø32mm bore and 350mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD32X350, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X350
The AirTAC SUD32X350 is a double-acting, double-rod profile cylinder featuring a 32 mm bore and 350 mm stroke. A rod exits both ends on a single piston, meaning push and pull forces are equal both ways at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. This design provides inherent anti-rotation properties and allows the rear rod to drive a secondary tool simultaneously. The extruded aluminium profile barrel is notably shorter than an ISO 15552 cylinder of the same bore. This SUD32X350 model is discontinued and end-of-life; the exact drop-in replacement is the SAUD32X350, which matches the 1/8" port, M10x1.25 rod thread, and FA/LB mounting.
For sizing, the computed safe working load is approximately 207 N (60% of the 345 N @0.5 MPa figure), translating to a vertical lift capacity of about 18 kg with a 2:1 margin. Because this SKU lacks a magnet, it cannot take a magnetic switch. The SAUD upgrade uses current CMSG/DMSG/EMSG sensors, whereas this discontinued model used legacy CS1-B/DS1-B switches. Note that a plain cylinder does not hold its load on air loss; the 21 mm adjustable air cushions only decelerate near stroke end, so an external rod lock is required for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X350 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 SAUD32X350 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 SUD32X350 Is Used
Dual-Tool Driving
Uses the protruding rear rod to operate a secondary mechanism simultaneously with the primary stroke, doubling process output without adding a second cylinder.
Anti-Rotation Transfer
The twin-rod geometry prevents the piston from twisting during traverse, ensuring precise linear movement for handling components.
Synchronized Push-Pull
Applies equal force both ways to push a part forward on one stroke and pull a fixture back on the return, maintaining balanced momentum.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X350 with the SAUD32X350
To replace the discontinued SUD32X350, specify the SAUD32X350 drop-in upgrade, which retains the 32 mm bore, 350 mm stroke, 1/8" port, and FA/LB mounting compatibility with the AirTAC SC series. When sizing both ways, verify that the equal-both-ways force (345 N @0.5 MPa) meets your requirements, or step up to the neighbouring 40 mm bore if more force is needed. A double rod is the right choice when you need anti-rotation stability or must drive two tools from one cylinder. Because this SKU has no magnet, it cannot take a sensor; the SAUD upgrade requires switching from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors. Finally, at the 350 mm stroke length, external guides are recommended to prevent rod bending under side loads.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X350
- ✓ 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 SUD32X350 FAQ
Yes, the SUD32X350 is discontinued. The exact drop-in replacement is the SAUD32X350, which matches the 32 mm bore, 350 mm stroke, 1/8" port, and FA/LB mounting.
Force is equal both ways: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. It operates at 0.15-1.0 MPa, runs at 30-800 mm/s, and uses a 1/8" port with a 21 mm adjustable cushion.
