This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X80S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X80S 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 SUD63X80S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X80S is a double-acting profile-type standard cylinder with a Ø63mm bore and 80mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD63X80S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X80S
The AirTAC SUD63X80S is a discontinued double-acting double-rod profile cylinder featuring a 63mm bore, 80mm stroke, and a 3/8 inch port. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal both ways at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The exact drop-in replacement is the SAUD63X80S, which matches the bore, stroke, force, port, and FA/LB mounting. The SAUD upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here, and offers an SAUF built-in-valve variant.
Because the second rod drives a sensor cam and resists rotation, this compact extruded aluminium profile barrel—shorter than an ISO 15552 cylinder of the same bore—is ideal for precise dual-tool driving. Based on the 1402 N @0.5 MPa rating, the computed safe working load is about 841 N (60%), translating to a vertical lift capacity of roughly 71 kg with a 2:1 margin. Note that a plain cylinder does not hold loads on air loss; the 21mm adjustable air cushion only decelerates near stroke end, so an external rod lock is required for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X80S 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 SAUD63X80S 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. |
| ×80 | 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 SUD63X80S Is Used
Dual-Tool Machining Station
Drives two opposing tools simultaneously from one piston, utilising the equal both-ways force to ensure balanced cutting or clamping pressure on both ends.
Anti-Rotation Transfer Gate
The twin rods prevent mechanical twisting during rapid part diversion on a packaging line, maintaining precise alignment without external guide rails.
Symmetric Sensor Cam Drive
Uses the rear exiting rod to carry a legacy CS1-B/DS1-B sensor cam, allowing external position tracking while the front rod performs the primary work.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X80S with the SAUD63X80S
To replace the discontinued SUD63X80S, specify the SAUD63X80S drop-in: it matches the 63mm bore, 80mm stroke, 3/8 inch port, and FA/LB mounting. When sizing both ways, verify the equal push/pull force fits your load—neighbouring bores (50mm or 80mm) offer 825/1154/1484 N or 2268/3175/4082 N respectively. A double rod is right when you need anti-rotation, a back rod to carry a sensor cam, or to drive two tools. For the -S magnet, change legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG on the SAUD. For stroke lengths >=300, check the side-load line to prevent guide wear. Mounting compatibility is with the AirTAC SC series only.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X80S
- ✓ 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 SUD63X80S FAQ
Yes, the SUD63X80S is discontinued. The exact drop-in replacement is the SAUD63X80S, which matches the 63mm bore, 80mm stroke, 3/8 inch port, and FA/LB mounting. You only need to upgrade the sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG.
Because it is a double-rod cylinder, the force is equal both ways (never a larger single-rod push value). It outputs 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The safe working load is about 841 N, allowing a vertical lift of roughly 71 kg with a 2:1 margin.
