This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X300S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X300S 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 SUD63X300S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X300S is a double-acting profile-type standard cylinder with a Ø63mm bore and 300mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD63X300S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X300S
The AirTAC SUD63X300S is a discontinued double-acting profile cylinder featuring a 63mm bore and 300mm stroke. A piston rod exits both ends, meaning push and pull forces are equal at 1402N @0.5MPa, 1962N @0.7MPa, and 2523N @0.9MPa. This double-rod geometry provides inherent anti-rotation stability and allows the rear rod to carry a sensor cam. The exact drop-in replacement is the SAUD63X300S, sharing the same 3/8" port, M16x1.5 rod thread, and FA/LB mounting.
For sizing, the 1402N @0.5MPa force yields a safe working load of roughly 841N, translating to a vertical lift capacity of about 71kg with a 2:1 margin. The extruded aluminum profile barrel is more compact than standard cylinders. Because this is a 300mm stroke, external guides are recommended to prevent rod bending under side loads. Note the -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; the SAUD successor uses current CMSG/DMSG/EMSG sensors. Air cushions decelerate the load but do not hold it without live air.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X300S 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 SAUD63X300S 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 SUD63X300S Is Used
Dual-Tool Transfer
Drives two independent mechanisms simultaneously from a single piston, utilizing the equal force from both rod ends to push and pull separate workpieces.
Anti-Rotation Diverter
The twin-rod design resists torsional twisting without external guides, ensuring stable diverting or sorting of heavy packages on a high-speed line.
Symmetric Lift Station
Lifts and lowers a platform using equal both-ways force, while the back rod conveniently mounts a sensor cam to track vertical position.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X300S with the SAUD63X300S
To replace the discontinued SUD63X300S, select the drop-in SAUD63X300S, which preserves the 63mm bore, 300mm stroke, 3/8" port, and FA/LB mounting. When sizing both ways, verify the equal push/pull force of 1402N @0.5MPa meets your requirement, or step to neighboring bores (50mm or 80mm) for different loads. Choose a double-rod cylinder when anti-rotation or driving two tools simultaneously is required. If using the -S magnet, upgrade from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For this 300mm stroke, ensure external guides support side loads to prevent rod bending. Remember, cushions only decelerate; use an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X300S
- ✓ 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 SUD63X300S FAQ
Yes, the SUD63X300S is discontinued. The exact drop-in replacement is the SAUD63X300S. It matches the 63mm bore, 300mm stroke, 3/8" port, and FA/LB mounting. You must upgrade the -S piston magnet 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: 1402N @0.5MPa, 1962N @0.7MPa, and 2523N @0.9MPa. The air port is 3/8". The 1402N @0.5MPa rating provides a safe working load of about 841N, or a 71kg vertical lift with a 2:1 margin.
