This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X40 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 SUD63X40
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X40 is a double-acting profile-type standard cylinder with a Ø63mm bore and 40mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD63X40, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X40
The AirTAC SUD63X40 is a double-acting, double-rod profile cylinder with a 63mm bore and 40mm stroke. Because a rod exits both ends on one piston, push and pull force are equal at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. This discontinued model used a 3/8" port, M16x1.5 rod thread, and adjustable 21mm cushions. The exact drop-in replacement is the SAUD63X40, which matches the bore, stroke, force, port, and FA/LB mounting.
This SKU has no magnet and cannot take a sensor. The SAUD upgrade switches to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B. The back rod provides anti-rotation support and can drive two tools. For sizing, the safe working load is ~841 N (60% of 1402 N), yielding a 71kg vertical lift with a 2:1 margin. A plain cylinder drifts on air loss; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X40 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 SAUD63X40 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.

| 63 | Bore size in mm. |
| ×40 | Stroke length in mm. |
| -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 SUD63X40 Is Used
Dual-Tool Machining Station
Uses the twin extending rods to drive two opposing machining heads simultaneously, ensuring perfectly synchronized cutting cycles without phase delay.
Anti-Rotation Transfer Gate
The second rod prevents piston rotation during rapid lateral transfers across the conveyor belt, maintaining precise alignment of the workpiece.
Balanced Vertical Lift
Equal push and pull force on both faces provides stable vertical lifting and lowering of 71kg palletized loads within automated storage racks.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X40 with the SAUD63X40
To replace the SUD63X40, use the SAUD63X40 drop-in: same 63mm bore, 40mm stroke, 3/8" port, and equal-both-ways force. If sizing both ways, compare neighbor bores (50mm or 80mm) to match the 1402 N @0.5 MPa output. Choose a double rod when you need anti-rotation or to drive two tools. Mounting is Basic, FA, or LB (SC series only). As this SKU lacks a magnet, it cannot take sensors; upgrading to SAUD with -S enables CMSG/DMSG/EMSG switches. For strokes >=300mm, verify side-load limits.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X40
- ✓ 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 SUD63X40 FAQ
Yes, the SUD63X40 is discontinued. The exact drop-in replacement is the SAUD63X40, which matches the 63mm bore, 40mm stroke, 3/8" port, and FA/LB mounting.
The 3/8" port bore delivers equal both ways force of 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The safe working load is ~841 N at 0.5 MPa.
