This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X160 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X160 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 SUD32X160
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X160 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 SAUD32X160, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X160
The AirTAC SUD32X160 is a discontinued double-acting, double-rod profile cylinder featuring a 32 mm bore and 160 mm stroke. A rod exits both ends on a single piston, meaning 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 SAUD32X160, retaining the same 1/8" port, M10x1.25 rod thread, and FA/LB mounting. This non-magnetic SKU cannot accept a sensor.
Because the second rod acts as an anti-rotation guide and can drive a second tool simultaneously, it offers distinct mechanical advantages. The computed safe working load is approximately 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. Note that the air cushion only decelerates the piston near stroke end; it does not hold loads on air loss, requiring an external rod lock for vertical holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X160 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 SAUD32X160 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 SUD32X160 Is Used
Dual-Tool Actuation
Drives two independent mechanisms simultaneously using both extending rod ends, ensuring perfectly synchronized timing for compact assembly stations.
Anti-Rotation Guidance
The dual-rod geometry prevents piston twisting under offset loads, maintaining precise alignment for pick-and-place units without external guides.
Symmetrical Transfer
Pushes a part forward on the extend stroke and retracts a second fixture backward on the pull stroke, doubling throughput in equal-force routing.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X160 with the SAUD32X160
To replace the discontinued SUD32X160, order the SAUD32X160 drop-in: it matches the 32 mm bore, 160 mm stroke, 1/8" port, and FA/LB mounting. Size both directions by checking the equal 345 N @0.5 MPa force against neighbouring bores to ensure your load fits. Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools from one piston. If upgrading sensing, note the SAUD uses CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For this 160 mm stroke, verify side-load alignment since stroke exceeds 300 mm.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X160
- ✓ 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 SUD32X160 FAQ
Yes, the SUD32X160 is discontinued. The exact drop-in replacement is the SAUD32X160, which shares the same 32 mm bore, 160 mm stroke, equal force, 1/8" port, and FA/LB mounting.
The SUD32X160 provides equal force both ways: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The fixed port size for the 32 mm bore is 1/8".
