This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD100X75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD100X75 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 SUD100X75
The AirTAC Airtac SUD Series Double Rod Cylinder SUD100X75 is a double-acting profile-type standard cylinder with a Ø100mm bore and 75mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD100X75, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD100X75
The AirTAC SUD100X75 is a double-acting double-rod profile cylinder that is officially discontinued. The exact drop-in replacement is the SAUD100X75, matching the 100mm bore, 75mm stroke, 1/2 inch port, and SC-series FA/LB mounts. Because a rod exits both ends on one piston, the push and pull force is equal both ways at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore.
This unit lacks a magnet (-S) and cannot take a magnetic switch, whereas the SAUD upgrade uses current CMSG/DMSG/EMSG sensors (this legacy model used CS1-B/DS1-B). The dual rods provide anti-rotation stability and let the back rod drive a second tool. For buyers, the safe working load is roughly 2209 N (about 60 percent of the 3681 N @0.5 MPa figure), yielding a vertical lift capacity of approximately 188 kg with a 2:1 margin. Note that a plain cylinder does not hold loads on air loss; the 29mm adjustable cushions only decelerate, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD100X75 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUD100X75 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 SUD100X75 Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously using both rod ends, ensuring perfectly synchronized part clamping and milling with equal push and pull force.
Anti-Rotation Transfer Gate
Uses the inherent anti-rotation resistance of the dual rods to smoothly actuate a heavy transfer gate on a packaging line without twisting or binding.
Vertical Lift Fixture
Lifts a 188 kg fixture in a vertical materials handling application, leveraging the equal both ways force to securely raise and lower the payload.
Replacing the Airtac SUD Series Double Rod Cylinder SUD100X75 with the SAUD100X75
To replace this discontinued SUD100X75, order the SAUD100X75 drop-in: just insert an A after the leading S, keeping the bore, stroke, and FA/LB mounting identical. Size both ways by checking the equal push/pull force against neighbouring bores (the 80mm bore yields 2268 N @0.5 MPa, while the 100mm yields 3681 N @0.5 MPa). Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools from one piston. Because this specific SKU lacks a magnet, it cannot take sensors; if you need position feedback, select the SAUD with -S and use CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes of 300mm or longer, verify the side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD100X75
- ✓ 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 SUD100X75 FAQ
Yes, the AirTAC SUD100X75 is discontinued. The exact drop-in replacement is the SAUD100X75, which matches the 100mm bore, 75mm stroke, 1/2 inch port, and FA/LB mounting. The SAUD also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
Because it is a double-rod cylinder, the force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. It operates at 30-800 mm/s with a 1/2 inch port and 29mm adjustable cushions at each end. The safe working load is about 2209 N.
