This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X70S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X70S 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 SUD63X70S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X70S is a double-acting profile-type standard cylinder with a Ø63mm bore and 70mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD63X70S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X70S
The AirTAC SUD63X70S is a double-acting, double-rod profile cylinder where a rod exits both ends, ensuring push and pull force are equal at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. This model is discontinued; the exact drop-in replacement is the SAUD63X70S, retaining the 63mm bore, 70mm stroke, 3/8" port, and FA/LB mounting. The extruded aluminum profile barrel is more compact than standard cylinders.
Because the rear rod can carry a sensor cam or drive a second tool simultaneously, the design prevents rotation without external guides. With a 0.5 MPa supply, the safe working load is roughly 841 N, and vertical lift capacity is about 71 kg with a 2:1 margin. This SUD63X70S includes a piston magnet for legacy CS1-B/DS1-B switches, while the SAUD upgrade uses current CMSG/DMSG/EMSG sensors. Note that air cushions only decelerate the piston; an external rod lock is required to hold loads safely.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X70S 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 SAUD63X70S 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. |
| ×70 | 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 SUD63X70S Is Used
Dual-Tool Synchronization
Drives two opposing tools from a single piston, utilizing the equal both-ways force to ensure perfectly synchronized machining or forming operations.
Anti-Rotation Transfer
Transfers parts across a conveyor belt using the double-rod profile to resist rotational torque without needing external linear guides.
Compact Vertical Lift
Lifts loads vertically in tight warehouse automation spaces, benefiting from the short profile barrel and equal push/pull force on the descent.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X70S with the SAUD63X70S
To replace the discontinued SUD63X70S, use the SAUD63X70S directly—the bore, stroke, 3/8" port, and FA/LB mounts are identical. When sizing both ways, verify the equal both-ways force fits your load, or step to neighboring bores (50mm or 80mm) if margins require. Choose a double-rod cylinder when you need anti-rotation stability or synchronous dual-tool driving. If upgrading, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches. For strokes of 300mm or longer, verify side-load limits to prevent guide wear. Remember, cushions only decelerate; use an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X70S
- ✓ 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 SUD63X70S FAQ
Yes, the SUD63X70S is discontinued. The exact drop-in replacement is the SAUD63X70S, which shares the same 63mm bore, 70mm stroke, 3/8" port, and FA/LB mounting. You only need to upgrade the 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: 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The air port is 3/8". The cylinder operates at 0.15-1.0 MPa with a speed range of 30-800 mm/s.
