This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD50X200S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD50X200S 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 SUD50X200S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD50X200S is a double-acting profile-type standard cylinder with a Ø50mm bore and 200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD50X200S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD50X200S
The AirTAC SUD50X200S is a double-acting, double-rod profile cylinder featuring a 50mm bore, 200mm stroke, and a 1/4 inch air port. A rod exits both ends on one piston, meaning both faces use the rod-side area and push and pull force are equal at 825N @0.5MPa, 1154N @0.7MPa, and 1484N @0.9MPa. This SUD model is discontinued and end-of-life; the exact drop-in replacement is the SAUD50X200S, which shares the same bore, stroke, force, port, and FA/LB mounting.
The rear rod provides an anti-rotation benefit and can carry a sensor cam to drive two tools simultaneously. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches, whereas the SAUD replacement uses current CMSG/DMSG/EMSG sensors. Based on the 825N @0.5MPa figure, the computed safe working load is about 495N, translating to a vertical lift capacity of roughly 42kg with a 2:1 margin. Note that a plain cylinder does not hold its load on air loss; the air cushion only decelerates near stroke end, so an external rod lock is recommended for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD50X200S 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 SAUD50X200S 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 SUD50X200S Is Used
Dual-Tool Machining Station
Simultaneously drives two opposing machining heads with equal push and pull force, using the second rod to carry a sensor cam for synchronized actuation.
Anti-Rotation Transfer Gate
Uses the double-rod geometry to prevent mechanical twist during high-speed part diversion, ensuring the gate remains perfectly aligned across the 200mm stroke.
Compact Vertical Lift
Lifts loads up to 42kg vertically in a tight packaging cell, taking advantage of the shorter profile barrel and equal both ways force for stable descent.
Replacing the Airtac SUD Series Double Rod Cylinder SUD50X200S with the SAUD50X200S
To replace the discontinued SUD50X200S, order the drop-in SAUD50X200S, which preserves the 50mm bore, 200mm stroke, 1/4 inch port, and FA/LB mounting compatibility with the AirTAC SC series. When sizing both ways, verify the equal push and pull force meets your needs; if more force is required, step up to the 63mm neighbour bore, or drop to 40mm for a smaller footprint. A double rod is right when you need anti-rotation stability or want to drive two tools from one cylinder. For the -S sensor change, swap legacy CS1-B/DS1-B switches for current CMSG/DMSG/EMSG sensors on the SAUD. For this 200mm stroke, which is under 300mm, side-load alignment is less critical, but always keep the load centered on the rod end thread M16x1.5 to prevent binding.
Replacement checklist
- ✓ Same bore / stroke → SAUD50X200S
- ✓ 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 SUD50X200S FAQ
Yes, the AirTAC SUD50X200S is discontinued and end-of-life. The exact drop-in replacement is the SAUD50X200S, which offers the same 50mm bore, 200mm stroke, 1/4 inch port, and FA/LB mounting. You must upgrade the piston magnet 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 @0.5MPa, 1154N @0.7MPa, and 1484N @0.9MPa. It operates at a speed of 30-800mm/s, features a 1/4 inch air port, and has an adjustable air cushion of 21mm at each end.
