This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X150S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X150S 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 SUD80X150S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X150S 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 SAUD80X150S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X150S
The AirTAC SUD80X150S is a discontinued double-acting double-rod profile cylinder featuring a 80mm bore and 150mm stroke. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal both ways at 2268N @0.5MPa, 3175N @0.7MPa and 4082N @0.9MPa. The bore dictates a 3/8 inch port, M20x1.5 rod thread and 28mm adjustable air cushions. As an end-of-life product, the exact drop-in replacement is the SAUD80X150S, retaining the same body, force, port and FA/LB mounting.
Because the rear rod can carry a sensor cam or drive two tools simultaneously while resisting rotation, this configuration is highly versatile. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches; the SAUD replacement upgrades to current CMSG/DMSG/EMSG sensors. For sizing, the 2268N @0.5MPa force yields a safe working load of roughly 1361N and a vertical lift capacity of about 116kg with a 2:1 margin. Remember that air cushions only decelerate near stroke end; an external rod lock is required for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X150S 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 SAUD80X150S 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 SUD80X150S Is Used
Dual-Tool Machining Station
Drives two opposing machining heads simultaneously from a single piston, utilising the equal both ways force to maintain perfectly balanced cutting pressure.
Anti-Rotation Transfer Unit
Transfers parts across a conveyor using the double-rod structure to prevent mechanical rotation during extension, ensuring components remain perfectly aligned.
Rear-Cam Sensing Press
Performs a light pressing operation on the front stroke while using the rear protruding rod to carry a sensor cam for precise position feedback.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X150S with the SAUD80X150S
To replace the discontinued SUD80X150S, specify the SAUD80X150S drop-in, which preserves the 80mm bore, 150mm stroke, 3/8 inch port, equal-both-ways force and FA/LB mounting. When sizing both ways, verify your force needs against the 2268N @0.5MPa or 3175N @0.7MPa ratings, or step to neighbouring bores if a higher margin is required. A double rod is the right choice when you need anti-rotation stability, want to drive two tools from one cylinder, or need to mount a sensor cam on the back rod. If upgrading, note the -S sensor change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. For stroke lengths of 300mm or greater, carefully check side-load guide alignment to prevent premature seal wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X150S
- ✓ 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 SUD80X150S FAQ
Yes, the SUD80X150S is discontinued. The exact drop-in replacement is the SAUD80X150S, which matches the 80mm bore, 150mm stroke, 3/8 inch port and equal force. You will only need to upgrade the switches from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.
Because it is a double-rod cylinder, the force is equal both ways at 2268N @0.5MPa, 3175N @0.7MPa and 4082N @0.9MPa. The safe working load is approximately 1361N, and it can vertically lift about 116kg with a 2:1 margin.
