This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD100X330 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD100X330 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 SUD100X330
The AirTAC Airtac SUD Series Double Rod Cylinder SUD100X330 is a double-acting profile-type standard cylinder with a Ø100mm bore and 330mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD100X330, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD100X330
The AirTAC SUD100X330 is a discontinued double-acting double-rod profile cylinder featuring a 100mm bore and 330mm stroke. A rod exits both ends on one piston, meaning push and pull force are equal at 3681N @0.5MPa, 5153N @0.7MPa, and 6626N @0.9MPa. It uses a 1/2 inch air port, a 25mm rod, and 29mm adjustable cushions. The exact drop-in replacement is the SAUD100X330, matching the bore, stroke, force, and SC-series FA/LB mounting.
This SKU has no magnet (-S omitted) and cannot take a magnetic switch. The SAUD upgrade switches to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B. For sizing, the safe working load is roughly 2209N (60% of the 0.5MPa force), yielding a vertical lift capacity of about 188kg with a 2:1 margin. The extruded aluminium body is compact, and the second rod prevents rotation while driving two tools. A plain cylinder drifts on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD100X330 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 SAUD100X330 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 SUD100X330 Is Used
Dual-Tool Pressing Station
Drives two opposing forming tools simultaneously using equal both-ways force, ensuring balanced pressure on both ends of the workpiece.
Anti-Rotation Transfer Gate
Uses the double-rod geometry to prevent piston rotation during long 330mm travel, maintaining precise alignment of the transfer mechanism.
Symmetrical Lift Fixture
Lifts loads vertically using the rod-side area on both faces, providing a stable safe working load of 2209N without requiring a larger bore.
Replacing the Airtac SUD Series Double Rod Cylinder SUD100X330 with the SAUD100X330
To replace the discontinued SUD100X330, order the drop-in SAUD100X330, which shares the exact 100mm bore, 330mm stroke, 1/2 inch port, and FA/LB mounting. Size both ways by checking neighbouring bores while confirming the equal both-ways force fits your load. Choose a double-rod design when you need anti-rotation, a back rod for a sensor cam, or to drive two tools. Because this non-magnetic SKU lacks a switch, migrate to CMSG/DMSG/EMSG sensors on the SAUD. For the 330mm stroke, add external guides to prevent rod bending under side-load. Note that cushions only decelerate; use an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUD100X330
- ✓ 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 SUD100X330 FAQ
Yes, the SUD100X330 is discontinued. The exact drop-in replacement is the SAUD100X330, which matches the 100mm bore, 330mm stroke, 1/2 inch port, and FA/LB mounting.
Force is equal both ways at 3681N @0.5MPa, 5153N @0.7MPa, and 6626N @0.9MPa. It features a 1/2 inch air port, a 25mm rod, and 29mm adjustable cushions.
