This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X160S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X160S 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 SUD80X160S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X160S 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 SAUD80X160S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X160S
The AirTAC SUD80X160S is a double-acting, double-rod profile cylinder where a rod exits both ends on one piston. Because both faces use the rod-side area, 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 discontinued model features a 80 mm bore, 160 mm stroke, 25 mm rod, M20x1.5 rod thread, and a 3/8" port. Its extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore.
This SUD80X160S is discontinued and the exact drop-in replacement is the SAUD80X160S, keeping the same bore, stroke, force, port, and FA/LB mounting. The double-rod design drives two tools and the back rod carries a sensor cam for the built-in magnet. For sizing, the safe working load is roughly 1361 N (60% of the 2268 N @0.5 figure) and vertical lift is about 116 kg with a 2:1 margin. Note the SAUD uses current CMSG/DMSG/EMSG sensors, whereas this SUD used legacy CS1-B/DS1-B switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X160S 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 SAUD80X160S 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 SUD80X160S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 80 | 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 SUD80X160S Is Used
Dual-Tool Machining Station
Drives two opposing tools simultaneously with equal push and pull force, ensuring balanced machining on both faces without requiring separate actuators.
Anti-Rotation Transfer Gate
The dual-rod construction prevents piston rotation during rapid transfer movements on the line, maintaining precise alignment of clamped parts.
Symmetric Sorting Diverter
Uses the rear rod to carry a sensor cam, allowing external position tracking while the front rod diverts packages symmetrically in both directions.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X160S with the SAUD80X160S
To replace the discontinued SUD80X160S, use the SAUD80X160S drop-in which matches the 80 mm bore, 160 mm stroke, 3/8" port, and equal-both-ways force. When sizing both ways, consider neighbor bores (63 mm or 100 mm) to meet your force requirements. A double rod is right when you need anti-rotation, two tool outputs, or a rear sensor cam. Mounting is Basic, FA, or LB only (SC series compatible). The -S suffix means a magnet is present; on the SAUD, change legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG. For stroke >=300 mm, confirm side-load limits. A plain cylinder does not hold loads on air loss; use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X160S
- ✓ 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 SUD80X160S FAQ
Yes, the SUD80X160S is discontinued. The exact drop-in replacement is the SAUD80X160S, which matches the 80 mm bore, 160 mm stroke, 3/8" port, and FA/LB mounting. You must change the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG sensors on the SAUD.
Because it is a double-rod cylinder, force is equal both ways at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. Operating speed is 30-800 mm/s. The safe working load is approximately 1361 N, and it does not hold loads without live air.
