This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD40X160S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD40X160S 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 SUD40X160S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD40X160S is a double-acting profile-type standard cylinder with a Ø40mm bore and 160mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD40X160S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD40X160S
The AirTAC SUD40X160S is a double-acting, double-rod profile cylinder featuring a 40mm bore and 160mm stroke. A rod exits both ends on one piston, meaning both faces use the rod-side area and push and pull force are equal at 528 N @0.5 MPa, 739 N @0.7 MPa, and 950 N @0.9 MPa. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore. This SUD model is discontinued and end-of-life; the exact drop-in replacement is the SAUD40X160S, which matches the bore, stroke, force, 1/4" port, and SC-series FA/LB mounting.
Because the second rod acts as an anti-rotation guide and can carry a sensor cam, it drives two tools simultaneously. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches, whereas the SAU replacement uses current CMSG/DMSG/EMSG sensors. For sizing, the safe working load is roughly 317 N (about 60% of the 528 N @0.5 MPa figure), allowing a vertical lift of approximately 27 kg with a 2:1 margin. Note that a plain cylinder does not hold its load on air loss; the 21mm adjustable air cushion only decelerates near stroke end, so an external rod lock is required for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD40X160S 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 SAUD40X160S 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 SUD40X160S Is Used
Dual-Tool Transfer
Simultaneously pushes and pulls two separate workpieces on a conveyor line using both extending rods, ensuring perfectly synchronized timing without adding a second cylinder.
Anti-Rotation Gripper
Powers a precision gripper where the second rod prevents the piston from twisting under offset loads, maintaining strict alignment during part clamping.
Symmetric Positioning
Indexes a carriage back and forth with identical force and speed in both directions, leveraging the equal push/pull areas for stable horizontal positioning.
Replacing the Airtac SUD Series Double Rod Cylinder SUD40X160S with the SAUD40X160S
To replace the discontinued SUD40X160S, use the SAUD40X160S drop-in: body, bore, stroke, equal force, 1/4" port, and FA/LB mounting are unchanged. If sizing both ways, compare neighbour bores (32mm or 50mm) to ensure the equal-both-ways force meets your needs. A double rod is right when you need anti-rotation stability or must drive two tools from one cylinder. The -S sensor change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG is required on the SAU. For this 160mm stroke, which is >=300mm, verify the side-load line to prevent excessive guide wear. Mounting compatibility is with the AirTAC SC series only.
Replacement checklist
- ✓ Same bore / stroke → SAUD40X160S
- ✓ 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 SUD40X160S FAQ
Yes, the SUD40X160S is discontinued. The exact drop-in replacement is the SAUD40X160S, which matches the 40mm bore, 160mm stroke, equal-both-ways force, 1/4" port, and FA/LB mounting. The SAU also offers the SAUF built-in-valve variant the SU line lacked.
Because it is a double-rod cylinder, force is equal both ways: 528 N @0.5 MPa, 739 N @0.7 MPa, and 950 N @0.9 MPa. The air port is 1/4" PT thread. It operates at 0.15-1.0 MPa with a 21mm adjustable air cushion at each end.
