This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X25S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X25S 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 SUD80X25S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X25S is a double-acting profile-type standard cylinder with a Ø80mm bore and 25mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X25S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X25S
The AirTAC SUD80X25S is a double-acting, double-rod profile cylinder featuring a 80mm bore and 25mm stroke. A piston rod exits both ends, meaning push and pull forces are equal at 2268N @0.5MPa, 3175N @0.7MPa, and 4082N @0.9MPa. The 3/8 inch port, M20x1.5 rod thread, and 28mm cushions match standard specifications. This SUD series is discontinued; the exact drop-in replacement is the SAUD80X25S, retaining the same profile body, bore, and SC-series FA/LB mounting.
Because both faces use the rod-side area, force is equal both ways, yielding a safe working load of roughly 1361N (60% of the 0.5MPa rating) and a vertical lift capacity of about 116kg with a 2:1 margin. The rear rod provides an anti-rotation benefit and can carry a sensor cam. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B switches; upgrading to the SAUD requires current CMSG/DMSG/EMSG sensors. Note that cushions only decelerate; use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X25S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAUD80X25S 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.
Model Code: Airtac SUD Series Double Rod Cylinder SUD80X25S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 80 | Bore size in mm. |
| ×25 | Stroke length in mm. |
| -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 SUD80X25S Is Used
Dual-Tool Machining Station
Drives two opposing tools simultaneously from a single compact body, utilizing 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 rotation during rapid part diversion on a packaging line, ensuring precise lateral movement.
Symmetric Sorting Diverter
Employs the back rod to carry a sensor cam for tracking position while pushing items equally in both directions without stroke variance.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X25S with the SAUD80X25S
To replace the discontinued SUD80X25S, specify the SAUD80X25S drop-in equivalent, which matches the 80mm bore, 25mm stroke, 3/8 port, and FA/LB mounting. Size both directions by checking the equal-both-ways force against your load, stepping to neighbour bores if needed. A double rod is right when you need anti-rotation, dual tool driving, or a rear sensor cam. When migrating the -S magnet option, swap the legacy CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors. For stroke lengths >=300mm, verify the side-load bearing limits to prevent guide wear. Remember, air cushions only decelerate; add an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X25S
- ✓ 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 SUD80X25S FAQ
Yes, the SUD80X25S is discontinued. The exact drop-in replacement is the SAUD80X25S, which shares the same 80mm bore, 25mm stroke, 3/8 port, and FA/LB mounting. You must upgrade the switches from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.
Because it is a double-rod cylinder, force is equal both ways: 2268N @0.5MPa, 3175N @0.7MPa, and 4082N @0.9MPa. The air port is 3/8 inch, the rod is Ø25mm with an M20x1.5 thread, and it includes 28mm adjustable cushions at each end.
