This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD100X75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD100X75S 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 SUD100X75S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD100X75S 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 SAUD100X75S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD100X75S
The AirTAC SUD100X75S is a discontinued double-acting double-rod profile cylinder with a 100mm bore and 75mm stroke. A rod exits both ends of the extruded aluminium barrel, meaning push and pull forces are equal both ways at 3681N @0.5MPa, 5153N @0.7MPa, and 6626N @0.9MPa. The exact drop-in replacement is the SAUD100X75S, which matches the 1/2" port, M20x1.5 rod thread, and 29mm cushions. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; the SAUD successor uses current CMSG/DMSG/EMSG sensors.
Because both faces use the rod-side area, the back rod can drive a second tool or carry a sensor cam without reducing extension force. For buyers sizing components, the safe working load is roughly 2209N (60% of the 0.5MPa force), allowing a vertical lift of about 188kg with a 2:1 margin. Note that the adjustable cushions only decelerate the load near stroke end; an external rod lock or pilot-operated check valve is required to hold a load securely on air loss, as a plain cylinder will drift.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD100X75S 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 SAUD100X75S 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 SUD100X75S Is Used
Dual-Tool Machining Station
Uses the protruding back rod to drive a secondary clamping or machining head, keeping the 3681N force equal in both directions without needing a second cylinder.
Anti-Rotation Divert Gate
The twin rods prevent the piston from twisting under offset loads, ensuring the diverting gate on the conveyor line moves smoothly without binding.
Symmetric Push-Pull Transfer
Moves a pallet precisely forward and backward with identical 5153N @0.7MPa force on both faces, ideal for rhythmic transfer operations between stations.
Replacing the Airtac SUD Series Double Rod Cylinder SUD100X75S with the SAUD100X75S
To replace the discontinued SUD100X75S, order the SAUD100X75S drop-in upgrade, which retains the exact bore, stroke, equal-both-ways force, 1/2" port, and FA/LB mounting. When sizing both ways, verify that 3681N @0.5MPa meets your dynamic requirements, or step to neighbouring bores if more force is needed. A double-rod design is correct when you need anti-rotation stability or must drive two tools simultaneously. If upgrading the -S magnet sensing, swap the old CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors. For this 75mm stroke, side-load alignment is forgiving, but for any stroke >=300mm, ensure the load guide is perfectly linear to prevent binding.
Replacement checklist
- ✓ Same bore / stroke → SAUD100X75S
- ✓ 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 SUD100X75S FAQ
Yes, the SUD100X75S is discontinued. The exact drop-in replacement is the SAUD100X75S. It matches the 100mm bore, 75mm stroke, 1/2" port, and FA/LB mounting. You must upgrade your sensors from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG series.
Because it is a double-rod cylinder, force is equal both ways: 3681N @0.5MPa, 5153N @0.7MPa, and 6626N @0.9MPa. The air port is 1/2" (PT thread standard), the piston rod is Ø25mm with an M20x1.5 thread, and it features 29mm adjustable cushions at each end.
