This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X240S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X240S 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 SUD63X240S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X240S is a double-acting profile-type standard cylinder with a Ø63mm bore and 240mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD63X240S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X240S
The AirTAC SUD63X240S is a double-acting, double-rod profile cylinder featuring a 63mm bore and 240mm stroke. A rod exits both ends on a single piston, meaning push and pull forces are equal both ways at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The SUD series is discontinued, but the exact drop-in replacement is the SAUD63X240S. It shares the same extruded aluminium profile barrel, 3/8" port, M16x1.5 rod thread, and Basic/FA/LB mounting. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches, whereas the SAUD replacement uses current CMSG/DMSG/EMSG sensors.
Choosing a double-rod design provides anti-rotation stability and allows the back rod to carry a sensor cam while driving two tools simultaneously. From the 1402 N @0.5 MPa force, the computed safe working load is approximately 841 N (60%), translating to a vertical lift capacity of about 71 kg with a 2:1 margin. This compact profile body is shorter than an ISO 15552 cylinder of the same bore. Note that a plain cylinder does not hold its load on air loss; the air cushion only decelerates near stroke end, so an external rod lock is required for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X240S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAUD63X240S 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 SUD63X240S Is Used
Dual-Tool Machining Station
Drives two opposing tools simultaneously from a single compact profile body, utilizing the equal both-ways force to ensure balanced cutting or clamping pressure.
Anti-Rotation Transfer Gate
The twin rods exiting both ends prevent mechanical twist during high-speed part diversion on a packaging line, maintaining precise alignment without external guides.
Symmetric Lifting Jig
Lifts and lowers a 71 kg vertical payload using the back rod to trigger legacy CS1-B/DS1-B position switches while the front rod handles the work.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X240S with the SAUD63X240S
To replace the discontinued SUD63X240S, specify the SAUD63X240S as a direct drop-in retaining the 63mm bore, 240mm stroke, 3/8" port, and Basic/FA/LB mounting. When sizing both ways, verify the equal-both-ways force fits your needs against neighbouring bores (50mm or 80mm). A double rod is right when you need anti-rotation stability or a back rod to carry a sensor cam. If using the -S magnet, change from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For this 240mm stroke (which is less than 300mm), side-load alignment is standard, but always mount rigidly with FA or LB brackets.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X240S
- ✓ 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 SUD63X240S FAQ
Yes, the AirTAC SUD63X240S is discontinued. The exact drop-in replacement is the SAUD63X240S, which matches the 63mm bore, 240mm stroke, 3/8" port, and FA/LB mounting. You only need to update the position sensors from legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG series.
Because it is a double-rod cylinder, the force is equal both ways at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The bore dictates a 3/8" air port, a 20mm rod, and an M16x1.5 rod thread. The safe working load is approximately 841 N.
