This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD100X80 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD100X80 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 SUD100X80
The AirTAC Airtac SUD Series Double Rod Cylinder SUD100X80 is a double-acting profile-type standard cylinder with a Ø100mm bore and 80mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD100X80, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD100X80
The AirTAC SUD100X80 is a discontinued double-acting, double-rod profile cylinder featuring a 100mm bore and 80mm stroke. A rod exits both ends of the extruded aluminum barrel, meaning push and pull forces are equal both ways at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. This compact design is shorter than an ISO 15552 cylinder and operates at 30-800 mm/s via a 1/2" port. The exact drop-in replacement is the SAUD100X80, retaining the same bore, stroke, force, and FA/LB mounting.
Because the rod exits both ends, the back rod can drive a second tool or act as an anti-rotation guide. This non-magnetic SKU cannot take a sensor, whereas the SAUD upgrade switches to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B. For sizing, the 3681 N @0.5 MPa force yields a safe working load of 2209 N (60%) and a vertical lift capacity of 188 kg with a 2:1 margin. Note that air cushions only decelerate; use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD100X80 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUD100X80 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 SUD100X80
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×80 | 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 SUD100X80 Is Used
Dual-Tool Machining Station
Drives two opposing machining heads simultaneously using both rod ends, ensuring perfectly synchronized part processing.
Anti-Rotation Transfer Unit
Uses the twin rods exiting both ends to prevent mechanical twisting during heavy lateral transfers on a packaging line.
Balanced Vertical Lift Gate
Lifts a 188 kg gate evenly with equal both ways force, preventing sagging and maintaining smooth vertical motion.
Replacing the Airtac SUD Series Double Rod Cylinder SUD100X80 with the SAUD100X80
To replace the discontinued SUD100X80, order the drop-in SAUD100X80, which matches the 100mm bore, 80mm stroke, 1/2" port, and FA/LB mounting. Size both ways by checking neighbor bores (80mm or 63mm) if you need less force, ensuring the equal both ways output fits your application. Choose a double-rod cylinder when you need anti-rotation stability or want to drive two tools from one piston. If upgrading to SAUD with the -S option, switch from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For strokes >=300, verify the side-load line to prevent guide wear. Remember, cushions only decelerate; install an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUD100X80
- ✓ 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 SUD100X80 FAQ
Yes, the SUD100X80 is discontinued. The exact drop-in replacement is the SAUD100X80, which shares the same 100mm bore, 80mm stroke, 1/2" port, and FA/LB mounting. The SAUD also offers the SAUF built-in-valve variant and uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The SUD100X80 provides force equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. It features a 1/2" port, a 25mm rod, adjustable 29mm cushions, and operates at 30-800 mm/s. This non-magnetic SKU cannot take a sensor.
