This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X175 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X175 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 SUD32X175
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X175 is a double-acting profile-type standard cylinder with a Ø32mm bore and 175mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD32X175, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X175
The AirTAC SUD32X175 is a double-acting, double-rod profile cylinder with a 32mm bore and 175mm stroke. A rod exits both ends on a single piston, meaning both faces use the rod-side area and push and pull force are equal at 345 N @0.5 MPa. This discontinued model is directly replaced by the SAUD32X175, which retains the exact bore, stroke, 1/8" port, and SC-series FA/LB mounting compatibility. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore.
Because the second rod can drive a second tool or carry a sensor cam, it provides anti-rotation stability without requiring external guides. Based on the 345 N @0.5 MPa output, the computed safe working load is roughly 207 N, translating to a vertical lift capacity of about 18 kg with a 2:1 margin. This SKU has no magnet (-S omitted), so it cannot accept legacy CS1-B/DS1-B switches, though the SAUD upgrade supports current CMSG/DMSG/EMSG sensors. Note that a plain cylinder does not hold loads on air loss; the 21mm adjustable cushions only decelerate near stroke end, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X175 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUD32X175 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 SUD32X175 Is Used
Dual-Tool Transfer
Drives two separate pick-and-place tools simultaneously from opposite rod ends, ensuring perfectly synchronized timing without adding a second cylinder.
Anti-Rotation Divert
Pushes a diverting gate on a packaging line where the second rod prevents the tool head from twisting under off-center side loads.
Symmetrical Clamping
Applies equal clamping force from both directions to hold a workpiece centered, leveraging the identical push and pull areas.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X175 with the SAUD32X175
To replace the SUD32X175, order the drop-in SAUD32X175, matching the 32mm bore, 175mm stroke, M10x1.25 rod thread, and 1/8" port. When sizing both ways, verify the equal force requirement against neighbor bores: the 32mm yields 345/483/621 N @0.5/0.7/0.9 MPa, so step up if higher force is needed. A double-rod design is right when you need equal both-ways force or anti-rotation stability. Mounting is limited to Basic, FA, and LB (SC-series only). Since this non-magnetic SKU cannot take sensors, upgrading to the SAUD allows CMSG/DMSG/EMSG switches. For this 175mm stroke (which is under 300mm), side-load alignment is less critical but still verify rod parallelism. Remember that air cushions only decelerate; add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X175
- ✓ 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 SUD32X175 FAQ
Yes, the SUD32X175 is discontinued. The exact drop-in replacement is the SAUD32X175. It matches the 32mm bore, 175mm stroke, 1/8" port, and FA/LB mounting, but uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
Because it is a double-rod cylinder, force is equal both ways: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. Operating speed ranges from 30-800 mm/s, with a 21mm adjustable air cushion at each end.
