This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X1150S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X1150S 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 SUD63X1150S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X1150S is a double-acting profile-type standard cylinder with a Ø63mm bore and 1150mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD63X1150S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X1150S
The AirTAC SUD63X1150S is a discontinued double-acting profile cylinder with a rod exiting both ends, yielding equal push and pull force of 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. It features a 63mm bore, 20mm rod, M16x1.5 thread, and a 3/8 inch port. The drop-in replacement is the SAUD63X1150S, matching the bore, stroke, force, and mounting.
Because both faces use the rod-side area, force is equal both ways and the back rod can drive a second tool or sensor cam. With a 1150mm stroke, external guides are recommended to manage side-load and rod bending. The 1402 N force at 0.5 MPa gives a safe working load of about 841 N and a vertical lift capacity of 71kg with a 2:1 margin. This SUD used legacy CS1-B/DS1-B sensors, while the SAUD uses CMSG/DMSG/EMSG switches. Air cushions only decelerate near stroke end; an external rod lock is needed to hold loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X1150S 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 SAUD63X1150S 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.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 63 | Bore size in mm. |
| ×1150 | 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 SUD63X1150S Is Used
Dual-Tool Transfer
Drives two opposing tools simultaneously from both rod ends, ensuring perfectly synchronized material handling on a conveyor line.
Anti-Rotation Pressing
The twin-rod construction prevents piston rotation during downstroke, delivering precise vertical pressing without external guides.
Long-Stroke Lifting
Handles vertical lift tasks up to 71kg with a 2:1 safety margin at 0.5 MPa, ideal for elevating goods in high-bay storage.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X1150S with the SAUD63X1150S
To replace the SUD63X1150S, order the SAUD63X1150S drop-in, which matches the 63mm bore, 1150mm stroke, 3/8 inch port, and FA/LB mounting. Size both ways by checking neighboring bores (50mm or 80mm) against your force needs, knowing this 63mm bore provides 1402 N at 0.5 MPa equally in both directions. Choose a double-rod cylinder when you need anti-rotation, equal force, or a back rod to carry a sensor cam. If your SUD has the -S magnet, note the SAU replacement switches from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For this 1150mm stroke, add external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss, so specify an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X1150S
- ✓ 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 SUD63X1150S FAQ
Yes, the SUD63X1150S is discontinued. The exact drop-in replacement is the SAUD63X1150S, which shares the same 63mm bore, 1150mm stroke, 3/8 inch port, and FA/LB mounting. You will only need to update your sensors from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG switches.
Because it is a double-rod cylinder, the push and pull forces are equal both ways. It outputs 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. The safe working load is about 841 N (60% of the 0.5 MPa figure).
