This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD50X160S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD50X160S 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 SUD50X160S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD50X160S is a double-acting profile-type standard cylinder with a Ø50mm bore and 160mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD50X160S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD50X160S
The AirTAC SUD50X160S is a double-acting double-rod profile cylinder featuring a 50mm bore, 160mm stroke, and a 1/4 inch air port. Because a rod exits both ends on one piston, both faces use the rod-side area, meaning push and pull force are equal both ways at 825 N @0.5 MPa. This model is discontinued and the exact drop-in replacement is the SAUD50X160S, retaining the same bore, stroke, force, port, and FA/LB mounting.
The double-rod design provides anti-rotation stability and allows the back rod to carry a sensor cam for legacy CS1-B/DS1-B switches, though the SAUD replacement upgrades to CMSG/DMSG/EMSG sensors. Based on the 825 N force at 0.5 MPa, the computed safe working load is about 495 N, translating to a vertical lift capacity of roughly 42 kg with a 2:1 margin. Note that the air cushion only decelerates near stroke end; an external rod lock is required for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD50X160S 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 SAUD50X160S 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.

| -S | Optional built-in magnet for sensor position sensing. |
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 SUD50X160S Is Used
Dual-Tool Machining
Drives two opposing tools simultaneously from a single piston, utilizing the equal both ways force for balanced material removal.
Anti-Rotation Transfer
Transfers parts along a conveyor belt using the double-rod geometry to prevent rotational drift during rapid 30-800 mm/s cycling.
Symmetric Push-Pull Sorting
Executes bidirectional sorting gates in packaging lines where the 825 N @0.5 MPa force and compact profile barrel save space.
Replacing the Airtac SUD Series Double Rod Cylinder SUD50X160S with the SAUD50X160S
To replace the discontinued SUD50X160S, use the drop-in SAUD50X160S, which matches the 50mm bore, 160mm stroke, 1/4 inch port, and FA/LB mounting. When sizing both ways, verify the equal force of 825 N @0.5 MPa fits your load, or step to neighbour bores like 40mm or 63mm. A double rod is right when you need anti-rotation or dual-tool driving. The -S sensor changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. For this 160mm stroke, which is under 300mm, side-load alignment is less critical but still recommended.
Replacement checklist
- ✓ Same bore / stroke → SAUD50X160S
- ✓ 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 SUD50X160S FAQ
Yes, the SUD50X160S is discontinued. The exact drop-in replacement is the SAUD50X160S, which offers the same 50mm bore, 160mm stroke, 1/4 inch port, and FA/LB mounting.
The force is equal both ways: 825 N @0.5 MPa, 1154 N @0.7 MPa, and 1484 N @0.9 MPa. The fixed air port size for the 50mm bore is 1/4 inch.
