This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X75 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 SUD63X75
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X75 is a double-acting profile-type standard cylinder with a Ø63mm bore and 75mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD63X75, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X75
The AirTAC SUD63X75 is a double-acting, double-rod profile cylinder featuring a 63mm bore and 75mm stroke. A rod exits both ends of the extruded aluminum barrel, 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. This SUD model is discontinued and the exact drop-in replacement is the SAUD63X75, which retains the 3/8" port, M16x1.5 rod thread, and FA/LB mounting. This non-magnetic SKU cannot take a sensor.
Because the second rod drives an external cam or a second tool while resisting rotation, it offers distinct mechanical advantages. Computed buyer insight: using the 0.5 MPa rating, the safe working load is roughly 841 N (60% of force), and the vertical lift capacity is about 71 kg with a 2:1 margin. Note that air cushions only decelerate near stroke end; an external rod lock is required for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X75 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 SAUD63X75 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 SUD63X75 Is Used
Dual-Tool Transfer
Simultaneously drives two independent grippers or tools from opposite rod ends to pick and place parts in a single cycle.
Anti-Rotation Indexing
The dual-rod geometry prevents piston rotation, providing precise linear positioning for indexing components without external guides.
Symmetrical Ejection
Pushes a product off a conveyor while the opposite rod retracts a diverter, maintaining equal force and balanced motion both ways.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X75 with the SAUD63X75
To replace this discontinued SUD63X75, select the SAUD63X75 drop-in equivalent, keeping the 63mm bore, 75mm stroke, and 3/8" port. When sizing both ways, verify your force requirements against the equal both ways ratings (1402 N @0.5, 1962 N @0.7) and check neighboring bores if you need a higher or lower capacity. Choose a double-rod configuration when you need anti-rotation stability or must drive two tools simultaneously. Mounting is limited to Basic, FA, and LB styles (SC-series compatible only). Because this specific SKU lacks a magnet, it cannot accept sensors; the SAUD upgrade uses current CMSG/DMSG/EMSG sensors. For stroke lengths >=300, carefully manage side-load alignment to prevent premature seal wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X75
- ✓ 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 SUD63X75 FAQ
Yes, the SUD63X75 is discontinued. The exact drop-in replacement is the SAUD63X75, which matches the 63mm bore, 75mm stroke, equal both ways force, and 3/8" port.
Force is equal both ways at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The air port is 3/8" with an M16x1.5 rod thread and 21mm adjustable cushions.
