This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X75 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 SUD80X75
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X75 is a double-acting profile-type standard cylinder with a Ø80mm bore and 75mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X75, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X75
The AirTAC SUD80X75 is a double-acting, double-rod profile cylinder that is officially discontinued; the exact drop-in replacement is the SAUD80X75. Because a rod exits both ends on one piston, both faces use the rod-side area, meaning push and pull force are equal at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore. This 80mm bore unit features a 25mm rod, M20x1.5 rod thread, 28mm adjustable air cushions, and a 3/8 inch port.
This SKU has no magnet (-S) and cannot take a magnetic switch. A key double-rod benefit is anti-rotation, while the back rod can drive a second tool. For buyers, the safe working load is roughly 1361 N (60% of the 0.5 MPa force), allowing a vertical lift of about 116 kg with a 2:1 margin. The SAUD80X75 successor retains the exact body, bore, stroke, force, port, and FA/LB mounting, but uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X75 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAUD80X75 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 SUD80X75 Is Used
Dual-Station Machining
Drives two opposing machining heads simultaneously using both rod ends, ensuring perfectly synchronized part processing.
Anti-Rotation Transfer
Transfers workpieces across a conveyor belt with high torsional resistance, preventing any unwanted rod rotation during transit.
Balanced Vertical Lift
Lifts a 116 kg fixture vertically with a 2:1 safety margin, utilizing the equal push and pull force for smooth descent.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X75 with the SAUD80X75
To replace the discontinued SUD80X75, order the SAUD80X75 drop-in equivalent, which matches the 80mm bore, 75mm stroke, 3/8 inch port, and FA/LB mounting. Size both ways by checking the equal-both-ways force: if 2268 N @0.5 MPa is insufficient, step up to the 100mm bore (3681 N), or drop to the 63mm bore (1402 N) if lower force is acceptable. Choose a double-rod cylinder when you need anti-rotation, or when the rear rod must drive a second mechanism. This non-magnetic SKU cannot accept sensors; the SAUD upgrade uses CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B. For strokes of 300mm or longer, verify the side-load limits to prevent guide wear. A plain cylinder does not hold loads on air loss—the cushion only decelerates near stroke end—so fit an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X75
- ✓ 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 SUD80X75 FAQ
Yes, the SUD80X75 is discontinued. The exact drop-in replacement is the SAUD80X75, which matches the 80mm bore, 75mm stroke, 3/8 inch port, and FA/LB mounting. The SAUD uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
Because it is a double-rod cylinder, force is equal both ways: 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The 80mm bore dictates a 3/8 inch port. The safe working load is approximately 1361 N.
