This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD50X100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD50X100S 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 SUD50X100S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD50X100S is a double-acting profile-type standard cylinder with a Ø50mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD50X100S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD50X100S
The AirTAC SUD50X100S is a double-acting, double-rod profile cylinder featuring a 50mm bore and 100mm stroke. A rod exits both ends on a single piston, meaning both faces use the rod-side area to deliver equal force both ways (825N at 0.5MPa, 1154N at 0.7MPa, 1484N at 0.9MPa). The extruded aluminium profile barrel is notably shorter than an ISO 15552 cylinder of the same bore. This SUD50X100S model is discontinued and the exact drop-in replacement is the SAUD50X100S, retaining the same 1/4" port, M16x1.5 rod thread, and FA/LB mounting.
The rear rod provides distinct advantages, acting as a sensor cam for position feedback and offering anti-rotation characteristics to prevent piston twist. This unit includes a piston magnet for legacy CS1-B/DS1-B switches, whereas the SAUD replacement uses current CMSG/DMSG/EMSG sensors. Based on the 825N force at 0.5MPa, the computed safe working load is approximately 495N, allowing a vertical lift of about 42kg with a 2:1 margin. Note that the adjustable 21mm air cushion only decelerates the piston near stroke end; an external rod lock is required for load holding on air loss.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD50X100S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAUD50X100S 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 SUD50X100S Is Used
Dual-Tool Machining Station
Drives two opposing machining heads simultaneously from one compact profile body, utilising the equal both-ways force to ensure balanced cutting pressure on both ends.
Anti-Rotation Transfer Gate
Uses the twin rods exiting both ends to prevent mechanical twist during rapid part diversion on a conveyor, maintaining precise alignment without external guides.
Symmetric Clamping Fixture
Clamps workpieces from both sides evenly. The rear rod acts as a sensor cam for legacy CS1-B/DS1-B switches to confirm clamp position before processing begins.
Replacing the Airtac SUD Series Double Rod Cylinder SUD50X100S with the SAUD50X100S
To replace the discontinued SUD50X100S, order the SAUD50X100S drop-in: it matches the 50mm bore, 100mm stroke, 1/4" port, and FA/LB mounting exactly. When sizing both ways, verify that the equal both-ways force (825N at 0.5MPa) meets your requirement, or step to neighbouring bores (63mm or 40mm) for more or less power. A double rod is right when you need anti-rotation stability or want to drive two tools simultaneously. If your SUD50X100S uses the -S magnet, note the sensor change from CS1-B/DS1-B to CMSG/DMSG/EMSG on the SAUD. For strokes of 300mm or longer, carefully check the side-load line to prevent guide bushing wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD50X100S
- ✓ 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 SUD50X100S FAQ
Yes, the SUD50X100S is discontinued. The exact drop-in replacement is the SAUD50X100S, which shares the same 50mm bore, 100mm stroke, 1/4" port, and FA/LB mounting. You will only need to upgrade the position sensors from legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG series.
Because it is a double-rod cylinder, the push and pull force are equal both ways: 825N at 0.5MPa, 1154N at 0.7MPa, and 1484N at 0.9MPa. The air port size is fixed at 1/4" for the 50mm bore. The safe working load is approximately 495N, which allows a vertical lift of about 42kg with a 2:1 margin.
