This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X150 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X150 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 SUD80X150
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X150 is a double-acting profile-type standard cylinder with a Ø80mm bore and 150mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X150, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X150
The AirTAC SUD80X150 is a double-acting, double-rod profile cylinder with an 80mm bore and 150mm stroke. A rod exits both ends on a single piston, meaning both faces use the rod-side area and push/pull force is equal both ways at 2268N @0.5 MPa, 3175N @0.7 MPa, and 4082N @0.9 MPa. This SUD model is discontinued; the exact drop-in replacement is the SAUD80X150, matching the 3/8" port, M20x1.5 rod thread, and 28mm adjustable cushion. The SAUD upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches.
Because the second rod drives a sensor cam or a second tool while resisting rotation, the compact aluminium profile body is highly versatile. From the 2268N @0.5 MPa figure, the computed safe working load is roughly 1361N, and the vertical lift capacity is about 116kg with a 2:1 margin. Note that this non-magnet SKU cannot take a magnetic switch, and a plain cylinder does not hold loads on air loss—the cushion only decelerates near stroke end, so an external rod lock is needed for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X150 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 SAUD80X150 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.

| -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 SUD80X150 Is Used
Dual-Tool Machining Station
Drives two opposing tools simultaneously from one piston, utilizing the equal both-ways force to machine parts on both the advance and retract strokes.
Anti-Rotation Transfer Gate
The twin rods prevent mechanical twisting during high-speed part diversion on a conveyor line, ensuring smooth lateral transfers without binding.
Symmetric Lift Platform
Lifts and lowers a 116kg vertical load with a 2:1 safety margin, using the back rod to carry a sensor cam for precise height positioning.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X150 with the SAUD80X150
To replace the discontinued SUD80X150, specify the SAUD80X150 drop-in: it preserves the 80mm bore, 150mm stroke, 3/8" port, and FA/LB mounting. Size both ways by checking neighbour bores (63mm or 100mm) to ensure the equal-both-ways force fits your system. Choose a double-rod cylinder when you need anti-rotation stability or to drive two tools simultaneously. If upgrading sensing, move from the old CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For stroke lengths of 300mm or over, verify the side-load line to prevent guide wear. Because air cushions only decelerate, add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X150
- ✓ 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 SUD80X150 FAQ
Yes, the SUD80X150 is discontinued. The exact drop-in replacement is the SAUD80X150, which matches the 80mm bore, 150mm stroke, 3/8" port, and FA/LB mounting, but uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
Force is equal both ways at 2268N @0.5 MPa, 3175N @0.7 MPa, and 4082N @0.9 MPa. The air port is 3/8". The computed safe working load is 1361N, allowing a 116kg vertical lift with a 2:1 margin.
