This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD80X175 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD80X175 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 SUD80X175
The AirTAC Airtac SUD Series Double Rod Cylinder SUD80X175 is a double-acting profile-type standard cylinder with a Ø80mm bore and 175mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD80X175, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD80X175
The AirTAC SUD80X175 is a double-acting, double-rod profile cylinder with an 80mm bore and 175mm stroke. Because a rod exits both ends, the push and pull forces are equal at 2268N @0.5MPa, 3175N @0.7MPa, and 4082N @0.9MPa. This discontinued model used an extruded aluminum barrel and a 3/8" port. The exact drop-in replacement is the SAUD80X175, which matches the bore, stroke, M20x1.5 rod thread, and SC-series FA/LB mounting.
This SKU has no internal magnet and cannot accept position sensors; the SAUD upgrade switches to current CMSG/DMSG/EMSG sensors for the -S variant. The dual-rod design provides anti-rotation stability and allows driving two tools simultaneously. Based on the 2268N @0.5MPa rating, the computed safe working load is approximately 1361N, yielding a vertical lift capacity of about 116kg with a 2:1 margin. Note that the air cushion only decelerates the piston near stroke end; an external rod lock is required to hold loads on air loss.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD80X175 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 SAUD80X175 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 SUD80X175 Is Used
Synchronized Tool Driving
Drives two separate work tools simultaneously from opposite rod ends with equal 2268N @0.5MPa force, ensuring perfectly matched timing without adding a second cylinder.
Anti-Rotation Guiding
The dual-rod architecture prevents piston rotation during travel, providing stable linear guidance for precision pick-and-place heads that cannot tolerate torsional play.
Symmetrical Transfer
Mounts on an FA bracket to push a product from one conveyor lane to another, using the rear rod to return an empty pallet while maintaining identical force both ways.
Replacing the Airtac SUD Series Double Rod Cylinder SUD80X175 with the SAUD80X175
To replace the SUD80X175, order the SAUD80X175 drop-in, which preserves the 80mm bore, 175mm stroke, 3/8" port, and FA/LB mounting. Size both directions by checking the equal both-ways force against your load: if 3175N @0.7MPa is insufficient, step up to the 100mm bore; if oversized, drop to the 63mm bore. Choose a double-rod cylinder when you need anti-rotation resistance or must drive two mechanisms from one piston. Since this specific SKU lacks a magnet, it cannot use switches; if sensing is needed, select the SAUD-S variant and use CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For this 175mm stroke, ensure the side-load is kept within the manufacturer's allowable limits.
Replacement checklist
- ✓ Same bore / stroke → SAUD80X175
- ✓ 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 SUD80X175 FAQ
Yes, the AirTAC SUD80X175 is discontinued. The exact drop-in replacement is the SAUD80X175, which matches the 80mm bore, 175mm stroke, 3/8" port, and FA/LB mounting. The SAUD also offers the SAUF built-in-valve variant and uses current CMSG/DMSG/EMSG sensors for the -S version.
The SUD80X175 has a 3/8" port and generates equal force both ways because it is a double-rod cylinder. The push and pull forces are 2268N @0.5MPa, 3175N @0.7MPa, and 4082N @0.9MPa. It operates at 30-800 mm/s with a 28mm adjustable air cushion at each end.
