This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD100X350S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD100X350S 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 SUD100X350S is a double-acting profile-type standard cylinder with a Ø100mm bore and 350mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD100X350S, which matches its bore, stroke, force and mounting.
The AirTAC SUD100X350S is a double-acting, double-rod profile cylinder featuring a 100mm bore and 350mm stroke. A rod exits both ends of the extruded aluminium barrel on a single piston, meaning both faces use the rod-side area and push/pull force is equal both ways at 3681N @0.5MPa, 5153N @0.7MPa, and 6626N @0.9MPa. This SUD model is discontinued and end-of-life; the exact drop-in replacement is the SAUD100X350S, which retains the same 1/2 inch port, M20x1.5 rod thread, and FA/LB mounting compatibility.
Because the second rod acts as an anti-rotation guide and can carry a sensor cam for dual-tool driving, it offers distinct mechanical advantages. With a 0.5MPa operating pressure, the computed safe working load is approximately 2209N (about 60% of the 3681N figure), allowing a vertical lift of roughly 188kg with a 2:1 margin. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches; when upgrading to the SAUD family, you must transition to current CMSG/DMSG/EMSG sensors. Note that air cushions only decelerate the piston near stroke end and do not hold loads on air loss.

The SAUD100X350S 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.
Uses the equal both-ways force of the double rod to drive opposing forming tools simultaneously, maintaining strict parallelism without rotational drift.
Employs the rear exiting rod to trigger a legacy CS1-B/DS1-B sensor cam while the front rod pushes heavy pallets along a 100mm bore profile cylinder line.
Lifts a 188kg gate with a 2:1 safety margin at 0.5MPa, relying on the symmetrical push and pull forces to prevent sagging during upward and downward travel.
To replace the discontinued SUD100X350S, specify the SAUD100X350S drop-in upgrade, matching the 100mm bore, 350mm stroke, 1/2 inch port, and FA/LB mounts. Size both ways by checking neighbouring bores while ensuring the equal-both-ways force requirement (3681N @0.5MPa) is met. A double-rod profile cylinder is right when you need anti-rotation stability or a rear rod to drive a second tool. The SAU replacement uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For this 350mm stroke, add external guides to prevent rod bending under side-load. For held loads, install an external rod lock or pilot-operated check valve, as cushions only decelerate.
Replacement checklist
Yes, the SUD100X350S is discontinued. The exact drop-in replacement is the SAUD100X350S, which matches the 100mm bore, 350mm stroke, 1/2 inch port, and FA/LB mounting.
Because it is a double-rod cylinder, force is equal both ways: 3681N @0.5MPa, 5153N @0.7MPa, and 6626N @0.9MPa. The 100mm bore uses a 1/2 inch port, features a 25mm rod, and has a 29mm adjustable cushion at each end.
