This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X160 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X160 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 SUD80X160
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X160 is a double-acting profile-type standard cylinder with a Ø80mm bore and 160mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X160, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X160
The AirTAC SUD80X160 is a double-acting, double-rod profile cylinder featuring an extruded aluminum barrel that is more compact than an ISO 15552 cylinder of the same bore. Because a rod exits both ends on one piston, both faces use the rod-side area, meaning push and pull force are equal both ways at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. This SUD80X160 model is discontinued and the exact drop-in replacement is the SAUD80X160, which retains the 80mm bore, 160mm stroke, 3/8" port, and FA/LB mounting.
The double-rod design provides excellent anti-rotation stability and allows the back rod to drive a second tool simultaneously. Based on the 2268 N @0.5 MPa force, the computed safe working load is approximately 1361 N, translating to a vertical lift capacity of about 116 kg with a 2:1 margin. Note that this specific SKU lacks a magnet and cannot take a magnetic switch; furthermore, a plain cylinder does not hold its load on air loss—the air cushion only decelerates near stroke end, so an external rod lock is required for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X160 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAUD80X160 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 SUD80X160 Is Used
Dual-Station Push Operation
Drives two opposing tooling heads simultaneously using both extending rods, ensuring perfectly synchronized part forming on a 160mm stroke.
Anti-Rotation Transfer Arm
Moves components between conveyor belts with high torsional resistance, preventing rod twist during rapid 30-800 mm/s lateral transfers.
Compact Vertical Lifter
Lifts loads up to 116 kg vertically using the equal both ways force, fitting into tight machinery envelopes where standard cylinders are too long.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X160 with the SAUD80X160
To replace the discontinued SUD80X160, select the drop-in SAUD80X160, which matches the 80mm bore, 160mm stroke, 3175 N equal-both-ways force @0.7 MPa, and FA/LB mounting. When sizing both ways, verify that your load requirements fit between the 63mm bore (1962 N @0.7 MPa) and 100mm bore (5153 N @0.7 MPa) neighbor options. A double rod is right when you need anti-rotation stability or must drive two tools from one piston. Because this SKU has no magnet (-S), it cannot support sensing; upgrading to the SAUD requires changing legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG models. For stroke lengths >=300, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X160
- ✓ 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 SUD80X160 FAQ
Yes, the SUD80X160 is discontinued. The exact drop-in replacement is the SAUD80X160, which matches the 80mm bore, 160mm stroke, 3/8" port, and FA/LB mounting. You will need to upgrade legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG models.
The SUD80X160 features a 3/8" port and delivers equal force both ways: 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. This yields a safe working load of ~1361 N and a vertical lift capacity of ~116 kg with a 2:1 margin.
