This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X160S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X160S 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 SUD32X160S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X160S is a double-acting profile-type standard cylinder with a Ø32mm bore and 160mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD32X160S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X160S
The AirTAC SUD32X160S is a discontinued double-acting double-rod profile cylinder featuring a 32mm bore, 160mm stroke, and a 1/8" port. Because a rod exits both ends on one piston, both faces use the rod-side area, making push and pull force equal at 345N @0.5 MPa. The drop-in replacement is the SAUD32X160S, which matches the bore, stroke, force, and mounting. The SAU upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this SUD, and offers an SAUF built-in-valve variant.
With a 12mm rod and M10x1.25 thread, this extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore. 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 207N (60% of the 345N @0.5 MPa figure), yielding a vertical lift capacity of about 18kg with a 2:1 margin. A plain cylinder does not hold loads on air loss; the air cushion only decelerates near stroke end, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X160S 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 SAUD32X160S 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 SUD32X160S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×160 | 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 SUD32X160S Is Used
Dual-Tool Pick & Place
Drives two opposing grippers simultaneously using both rod ends, ensuring perfectly synchronized part transfer without adding a second cylinder.
Anti-Rotation Guiding
The twin rods prevent piston twisting during vertical clamping, maintaining precise alignment for pressing or holding small components.
Symmetrical Stops
Extends a stop gate from either end of a conveyor lane, providing equal blocking force regardless of the incoming product direction.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X160S with the SAUD32X160S
To replace the SUD32X160S, order the drop-in SAUD32X160S, which matches the 32mm bore, 160mm stroke, 1/8" port, and FA/LB mounting. When sizing both ways, check the 345N @0.5 MPa equal force against neighbor bores to ensure capacity. A double rod is right when you need anti-rotation stability or want to drive two tools. For the -S magnet, change from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For this 160mm stroke (>=300mm note applies to longer variants), verify the side-load line to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X160S
- ✓ 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 SUD32X160S FAQ
Yes, the SUD32X160S is discontinued. The exact drop-in replacement is the SAUD32X160S, which matches the 32mm bore, 160mm 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 1/8" port cylinder operates at 30-800 mm/s with adjustable 21mm cushions.
