This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD40X160 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD40X160 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 SUD40X160
The AirTAC Airtac SUD Series Double Rod Cylinder SUD40X160 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 SAUD40X160, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD40X160
The AirTAC SUD40X160 is a double-acting, double-rod profile cylinder featuring a 40mm bore and 160mm stroke. A rod exits both ends on a single piston, meaning push and pull forces are equal both ways at 528N @0.5MPa, 739N @0.7MPa, and 950N @0.9MPa. This discontinued model used a 1/4" port and M12x1.25 rod thread. The exact drop-in replacement is the SAUD40X160, matching the bore, stroke, force, and FA/LB mounting.
This SKU lacks a magnet (-S) and cannot take a magnetic switch. The double-rod design provides anti-rotation stability and allows driving two tools simultaneously. For sizing, the safe working load is roughly 317N (60% of the 528N @0.5MPa figure), yielding a vertical lift capacity of about 27kg with a 2:1 margin. Note that air cushions only decelerate the piston near stroke end; an external rod lock is required to hold loads without live air.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD40X160 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 SAUD40X160 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 SUD40X160 Is Used
Twin-Tool Machining
Drives two opposing tools simultaneously from one piston, ensuring perfectly synchronized opposing operations with equal force.
Anti-Rotation Transfer
The dual-rod geometry prevents piston rotation during horizontal part transfer on conveyor lines, maintaining precise alignment.
Symmetric Push-Pull
Ideal for compact sorting gates requiring identical push and pull forces to divert packages evenly in both directions.
Replacing the Airtac SUD Series Double Rod Cylinder SUD40X160 with the SAUD40X160
To replace the discontinued SUD40X160, use the SAUD40X160 drop-in upgrade, which retains the 40mm bore, 160mm stroke, equal-both-ways force, 1/4" port, and SC-series FA/LB mounting. Because force is identical in both directions, size both ways by comparing neighbouring bores (32mm or 50mm) against your exact push and pull requirements. Choose a double-rod cylinder when anti-rotation stability or driving two tools from one piston is needed. This non-magnetic SKU cannot support sensors; the SAUD upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For stroke lengths of 300mm or greater, carefully verify side-load limits to prevent guide bushing wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD40X160
- ✓ 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 SUD40X160 FAQ
Yes, the SUD40X160 is discontinued. The exact drop-in replacement is the SAUD40X160, which matches the 40mm bore, 160mm stroke, 1/4" port, and FA/LB mounting.
Because it is a double-rod cylinder, force is equal both ways: 528N @0.5MPa, 739N @0.7MPa, and 950N @0.9MPa. The bore dictates a 1/4" port, and it operates at 30-800mm/s.
