This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X280S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X280S 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 SUD63X280S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X280S is a double-acting profile-type standard cylinder with a Ø63mm bore and 280mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD63X280S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X280S
The AirTAC SUD63X280S is a double-acting, double-rod profile cylinder featuring a 63mm bore and 280mm stroke. Because a rod exits both ends on a single piston, push and pull forces are equal at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. This SUD model is discontinued; its exact drop-in replacement is the SAUD63X280S, retaining the 3/8" port, M16x1.5 rod thread, and FA/LB mounting. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore.
For practical sizing, the safe working load is roughly 841 N (about 60% of the 1402 N @0.5 MPa figure), translating to a vertical lift capacity of approximately 71 kg with a 2:1 margin. The rear rod provides an anti-rotation benefit and carries a sensor cam for stable mounting. This -S variant includes a piston magnet for legacy CS1-B/DS1-B switches; the SAUD replacement upgrades this to current CMSG/DMSG/EMSG sensors. A plain cylinder does not hold loads without live air, as the cushion only decelerates near stroke end.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X280S 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 SAUD63X280S 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 SUD63X280S Is Used
Dual-Tool Machining Station
Drives two opposing tools simultaneously from one piston, utilizing the equal both-ways force to maintain balanced cutting pressure on both ends.
Anti-Rotation Transfer Unit
The second rod prevents mechanical rotation during part transfer across a conveyor, ensuring precise placement without external linear guides.
Symmetric Clamping Fixture
Clamps workpieces from both sides evenly. The matched push and pull forces of 1962 N @0.7 MPa provide equal pressure without complex valving.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X280S with the SAUD63X280S
To replace the discontinued SUD63X280S, use the SAUD63X280S drop-in, which matches the 63mm bore, 280mm stroke, equal-both-ways force, and FA/LB mounting. When sizing both ways, verify the 1402 N @0.5 MPa force fits your load, or step to neighboring bores (50mm or 80mm) for different capacities. Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools simultaneously. The -S suffix means you must change legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG on the SAUD. For this 280mm stroke (>=300mm threshold approaching), ensure adequate side-load guidance to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X280S
- ✓ 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 SUD63X280S FAQ
Yes, the SUD63X280S is discontinued. The exact drop-in replacement is the SAUD63X280S, which matches the 63mm bore, 280mm stroke, 3/8" port, and FA/LB mounting. You must upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG sensors on the SAUD.
Because it is a double-rod cylinder, force is equal both ways: 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The air port is 3/8" (PT thread), the piston rod is Ø20 mm with an M16x1.5 thread, and it operates at 30-800 mm/s with 21 mm adjustable cushions at each end.
