This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X80 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X80 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.

The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X80 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 SAUD63X80, which matches its bore, stroke, force and mounting.
The AirTAC SUD63X80 is a double-acting, double-rod profile cylinder featuring a 63mm bore and 80mm stroke. Because a rod exits both ends on one piston, push and pull force are equal at 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. This SUD model is discontinued; the exact drop-in replacement is the SAUD63X80, retaining the same 3/8" port, M16x1.5 rod thread, and FA/LB mounting. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore.
This non-magnetic SKU cannot take a sensor switch. The rear rod provides an anti-rotation benefit and can drive a second tool simultaneously. For sizing, the safe working load is roughly 841 N (60% of the 0.5 MPa force), yielding a vertical lift capacity of about 71 kg with a 2:1 margin. Note that a plain cylinder does not hold loads on air loss; the 21mm adjustable air cushions only decelerate near stroke end, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X80 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAUD63X80 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.
Drives two opposing machining heads simultaneously using both rod ends, ensuring perfectly synchronized part processing.
Uses the twin-rod geometry to prevent piston rotation during lateral part diversion on a high-speed packaging line.
Lifts balanced loads vertically with equal force both ways, safely raising up to 71 kg with a 2:1 safety margin at 0.5 MPa.
To replace the discontinued SUD63X80, order the drop-in SAUD63X80, which matches the 63mm bore, 80mm stroke, 3/8" port, and FA/LB mounting. Size both directions by checking the equal-both-ways force against neighbouring bores (50mm or 80mm) to ensure your push and pull requirements are met. Choose a double-rod cylinder when you need anti-rotation stability or to drive two tools from one piston. Because this non-magnetic SKU lacks a sensor cam, the SAUD upgrade path uses current CMSG/DMSG/EMSG sensors (the SUD used legacy CS1-B/DS1-B). For strokes >=300mm, verify the side-load limits to prevent guide wear.
Replacement checklist
Yes, the SUD63X80 is discontinued. The exact drop-in replacement is the SAUD63X80, which keeps the same 63mm bore, 80mm stroke, equal-both-ways force, 3/8" port, and FA/LB mounting.
The 3/8" ported, double-rod SUD63X80 provides equal force both ways: 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. It never quotes a larger single-rod push value.
