This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X175S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X175S 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 SUD32X175S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X175S 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 SAUD32X175S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X175S
The AirTAC SUD32X175S is a double-acting, double-rod profile cylinder featuring a 32mm bore, 175mm stroke, and a 1/8 inch port. Because a rod exits both ends on a single piston, the push and pull forces are equal both ways at 345N @0.5 MPa, 483N @0.7 MPa, and 621N @0.9 MPa. This model is discontinued and the exact drop-in replacement is the SAUD32X175S, which matches the bore, stroke, force, port, and FA/LB mounting.
The rear rod provides an anti-rotation benefit and carries a sensor cam for stable guiding. With a 345N force at 0.5 MPa, the computed safe working load is roughly 207N, allowing a vertical lift of about 18kg with a 2:1 margin. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches, while the SAUD replacement uses current CMSG/DMSG/EMSG sensors. Note that air cushions only decelerate near stroke end; an external rod lock is required for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X175S 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 SAUD32X175S 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 SUD32X175S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×175 | 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 SUD32X175S Is Used
Dual-Tool Driving
Simultaneously operates two separate tooling heads from one compact 32mm bore profile body, ensuring synchronized motion without external linkages.
Anti-Rotation Guiding
The dual-rod design prevents piston rotation during travel, providing precise linear positioning for delicate handling tasks.
Symmetrical Transfer
Pushes and pulls loads with equal 345N force at 0.5 MPa, ideal for transferring parts between conveyor stations from either end.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X175S with the SAUD32X175S
To replace this discontinued SUD32X175S, order the SAUD32X175S drop-in, keeping the 32mm bore, 175mm stroke, 1/8 inch port, and FA/LB mounting identical. Size both ways by checking neighboring bores (40mm) to ensure the equal-both-ways force fits your application. Choose a double-rod cylinder when you need anti-rotation stability or need to drive two tools simultaneously. For the -S sensor change, swap legacy CS1-B/DS1-B switches for current CMSG/DMSG/EMSG sensors. For this 175mm stroke, which is under 300mm, side-load alignment is standard, but always verify guiding if operating at the 30-800 mm/s speed range.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X175S
- ✓ 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 SUD32X175S FAQ
Yes, the SUD32X175S is discontinued. The exact drop-in replacement is the SAUD32X175S, which matches the 32mm bore, 175mm stroke, 1/8 inch port, and FA/LB mounting. You only need to upgrade the sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
Because it is a double-rod cylinder, the force is equal both ways: 345N @0.5 MPa, 483N @0.7 MPa, and 621N @0.9 MPa. The operating speed is 30-800 mm/s, and it features a 21mm adjustable air cushion at each end.
