This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X70S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X70S 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 SUD32X70S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X70S is a double-acting profile-type standard cylinder with a Ø32mm bore and 70mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD32X70S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X70S
The AirTAC SUD32X70S is a double-acting double-rod profile cylinder featuring a 32 mm bore and 70 mm stroke. 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. This model is discontinued and the exact drop-in replacement is the SAUD32X70S, which matches the bore, stroke, 1/8 inch port, and mounting. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore.
Because the rear rod can carry a sensor cam or drive two tools simultaneously while resisting rotation, the double-rod layout offers distinct mechanical advantages. With a 345 N @0.5 MPa output, the computed safe working load is about 207 N, translating to a vertical lift capacity of roughly 18 kg with a 2:1 margin. The built-in piston magnet works with legacy CS1-B/DS1-B switches, while the SAUD replacement upgrades to current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X70S 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 SAUD32X70S 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 SUD32X70S Is Used
Dual-Tool Transfer
Drives two opposing pick-and-place tools from a single piston, utilizing the equal both-ways force to maintain cycle symmetry.
Anti-Rotation Indexing
The twin rod design prevents piston rotation during travel, providing stable positioning for indexing mechanisms without external guides.
Symmetrical Sorting
Pushes product alternately left and right on a conveyor line, leveraging the identical push and pull forces for consistent sorting.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X70S with the SAUD32X70S
To replace the discontinued SUD32X70S, specify the SAUD32X70S drop-in equivalent, which preserves the 32 mm bore, 70 mm stroke, 1/8 inch port, and FA/LB mounting compatibility with the AirTAC SC series. When sizing both ways, verify that the equal push and pull forces of 345 N @0.5 MPa, 483 N @0.7 MPa, or 621 N @0.9 MPa meet your requirements, or step up to a larger bore if higher force is needed. Choose a double-rod cylinder when anti-rotation stability or driving two tools from one piston is required. For the -S magnet option, note that the SAU replacement uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches. For stroke lengths of 300 mm or greater, carefully manage side-load alignment to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X70S
- ✓ 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 SUD32X70S FAQ
Yes, the SUD32X70S is discontinued. The exact drop-in replacement is the SAUD32X70S, which matches the 32 mm bore, 70 mm stroke, 1/8 inch port, and FA/LB mounting. You only need to upgrade the sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
Because it is a double-rod cylinder, the push and pull forces are identical: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The air port is 1/8 inch. Note that the air cushion only decelerates near stroke end; use an external rod lock for load holding.
