This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD40X100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD40X100S 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 SUD40X100S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD40X100S is a double-acting profile-type standard cylinder with a Ø40mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD40X100S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD40X100S
The AirTAC SUD40X100S is a double-acting, double-rod profile cylinder with a 40mm bore and 100mm stroke. A rod exits both ends on one piston, meaning push and pull force are equal both ways at 528N @0.5MPa, 739N @0.7MPa, and 950N @0.9MPa. This model is discontinued; the exact drop-in replacement is the SAUD40X100S, retaining the 1/4" port, M12x1.25 rod thread, and 21mm cushions.
The rear rod provides an anti-rotation benefit and can drive a second tool or carry a sensor cam. With a safe working load of roughly 317N (60% of the 528N @0.5MPa rating), it handles vertical lifts up to 27kg with a 2:1 margin. Note that the air cushion only decelerates near stroke end; use an external rod lock for load holding without live air.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD40X100S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAUD40X100S 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 SUD40X100S Is Used
Dual-Tool Transfer
Simultaneously drives two opposing grippers or pickers from a single compact body, keeping cycle times low without adding a second cylinder.
Anti-Rotation Indexing
The twin-rod geometry prevents piston rotation during travel, holding strict angular alignment for parts feeding and precision indexing.
Balanced Vertical Lift
Equal push and pull forces make it ideal for raising and lowering 27kg vertical loads with a 2:1 safety margin at 0.5MPa.
Replacing the Airtac SUD Series Double Rod Cylinder SUD40X100S with the SAUD40X100S
To replace the discontinued SUD40X100S, order the SAUD40X100S drop-in (insert A after S). Body, bore, stroke, equal-both-ways force, 1/4" port, and FA/LB mounting are unchanged. If sizing both ways, check the 32mm and 50mm neighbour bores to match your exact equal-force requirements. Choose a double-rod cylinder when you need anti-rotation or must drive two tools simultaneously. Because this is an -S model, swap the legacy CS1-B/DS1-B sensors for current CMSG/DMSG/EMSG switches on the SAUD. For stroke lengths >=300mm, verify the side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD40X100S
- ✓ 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 SUD40X100S FAQ
Yes, the SUD40X100S is discontinued. The exact drop-in replacement is the SAUD40X100S, which matches the 40mm bore, 100mm stroke, 1/4" port, and FA/LB mounting. You only need to upgrade the sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG.
Because it is a double-rod cylinder, force is equal both ways: 528N @0.5MPa, 739N @0.7MPa, and 950N @0.9MPa. The 40mm bore uses a 1/4" air port, a 16mm rod, and adjustable 21mm cushions at each end.
