This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X1000SLB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X1000SLB 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 SUD63X1000SLB
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X1000SLB is a double-acting profile-type standard cylinder with a Ø63mm bore and 1000mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD63X1000SLB, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X1000SLB
The AirTAC SUD63X1000SLB is a discontinued double-acting profile cylinder with a rod exiting both ends, yielding equal force in both directions (1402 N at 0.5 MPa). The drop-in replacement is the SAUD63X1000SLB, retaining the 63mm bore, 1000mm stroke, 3/8 inch port, and LB mounting interface. The SAUD upgrades the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
With a 1000mm stroke, external guides are essential to prevent rod bending under side loads. The equal push and pull force makes it ideal for driving two tools simultaneously or using the rear rod as a sensor cam. Based on the 1402 N output, the safe working load is roughly 841 N, translating to a 71 kg vertical lift with a 2:1 margin. Note that air cushions only decelerate; an external rod lock is required for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X1000SLB 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 SAUD63X1000SLB 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. |
| ×1000 | 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 SUD63X1000SLB Is Used
Dual-Tool Machining Station
Drives two opposing machining heads simultaneously with equal 1402 N force at 0.5 MPa, ensuring balanced material removal on both sides.
Symmetric Transfer Pusher
Uses both rod ends to push and retract parts across a conveyor belt, maintaining equal push and pull force for precise positioning.
Guided Lift Elevator
Lifts a 71 kg vertical load with a 2:1 safety margin, while the second rod operates a rear sensor cam for position feedback.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X1000SLB with the SAUD63X1000SLB
To replace the SUD63X1000SLB, order the SAUD63X1000SLB directly; the profile body, 3/8 inch port, 20mm rod, and LB mount interface are identical. Because force is equal both ways, size by checking neighbouring bores against the 1402 N output at 0.5 MPa. Choose a double-rod design when you need anti-rotation stability or must drive two mechanisms. The -S option changes from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For this 1000mm stroke, always support the load with external guides to prevent rod bending. Remember that cushions only decelerate; use an external rod lock for holding.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X1000SLB
- ✓ 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 SUD63X1000SLB FAQ
Yes, the SUD63X1000SLB is discontinued. The exact drop-in replacement is the SAUD63X1000SLB, which matches the 63mm bore, 1000mm stroke, 3/8 inch port, and 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, the force is 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 approximately 841 N, yielding a 71 kg vertical lift capacity with a 2:1 margin.
