This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD50X150S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD50X150S 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 SUD50X150S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD50X150S is a double-acting profile-type standard cylinder with a Ø50mm bore and 150mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD50X150S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD50X150S
The AirTAC SUD50X150S is a double-acting, double-rod profile cylinder featuring a 50mm bore and 150mm stroke. A rod exits both ends of the extruded aluminium barrel, meaning push and pull forces are equal both ways at 825N @0.5 MPa, 1154N @0.7 MPa, and 1484N @0.9 MPa. This discontinued model is directly replaced by the SAUD50X150S, which retains the exact 1/4" port, M16x1.5 rod thread, and FA/LB mounting dimensions.
Because the rear rod can drive a second tool or carry a sensor cam, the design offers excellent anti-rotation stability. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches; the SAUD replacement upgrades this to current CMSG/DMSG/EMSG sensors. For sizing, the 825N @0.5 MPa force yields a safe working load of 495N and a vertical lift capacity of roughly 42kg with a 2:1 margin. Note that the air cushion only decelerates the piston near stroke end; an external rod lock is required to hold loads on air loss.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD50X150S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAUD50X150S 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 SUD50X150S Is Used
Dual-Tool Machining Station
Drives two opposing operations simultaneously using both rod ends, ensuring perfectly synchronized part processing without adding a second cylinder.
Anti-Rotation Transfer Gate
Uses the double-rod geometry to prevent piston twisting during lateral product diversion on a packaging line, ensuring smooth linear motion.
Symmetric Clamping Fixture
Applies equal clamping force from both sides of a workpiece simultaneously, holding delicate components securely without offset loads.
Replacing the Airtac SUD Series Double Rod Cylinder SUD50X150S with the SAUD50X150S
To replace the discontinued SUD50X150S, order the drop-in SAUD50X150S, matching the 50mm bore, 150mm stroke, and 1/4" port. When sizing both ways, verify your force requirements against the equal both-ways ratings (825N @0.5, 1154N @0.7, 1484N @0.9) and check neighbouring bores if you need more or less power. Choose a double-rod setup when you need anti-rotation stability or want to drive two tools from one cylinder. Mounting is limited to Basic, FA, and LB (SC-series compatible only). For the -S magnet option, swap legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAUD. For stroke lengths of 300mm or greater, carefully manage side-load alignment to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD50X150S
- ✓ 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 SUD50X150S FAQ
Yes, the SUD50X150S is discontinued. The exact drop-in replacement is the SAUD50X150S, which matches the 50mm bore, 150mm stroke, equal both-ways force, 1/4" port, and FA/LB mounting. You only need to upgrade the sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
Because it is a double-rod cylinder, force is equal both ways: 825N @0.5 MPa, 1154N @0.7 MPa, and 1484N @0.9 MPa. The air port is 1/4" (PT thread), the piston rod is Ø20mm with an M16x1.5 thread, and it includes a 21mm adjustable cushion at each end. The cushion only decelerates the piston; it does not hold loads on air loss.
