This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD32X75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD32X75S 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 SUD32X75S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD32X75S is a double-acting profile-type standard cylinder with a Ø32mm bore and 75mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD32X75S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD32X75S
The AirTAC SUD32X75S is a discontinued double-acting double-rod profile cylinder with a 32mm bore and 75mm stroke. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal (345N at 0.5MPa). It features a 1/8 inch port, M10x1.25 rod thread, and an extruded aluminium profile barrel shorter than an ISO 15552 cylinder. This legacy model is replaced by the drop-in SAUD32X75S, which retains the exact bore, stroke, force, and FA/LB mounting.
Because the second rod drives a sensor cam and resists rotation, double-rod builds suit guided mechanisms. The S-suffix magnet works with legacy CS1-B/DS1-B switches, whereas the SAUD replacement uses current CMSG/DMSG/EMSG sensors. For sizing, the 345N force at 0.5MPa yields a safe working load of 207N and a vertical lift capacity of about 18kg with a 2:1 margin. Note that air cushions only decelerate near stroke end; an external rod lock is required to hold loads safely.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD32X75S 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 SAUD32X75S 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 SUD32X75S Is Used
Dual-Tool Pick & Place
Drives two opposing grippers simultaneously using both extending rods, ensuring perfectly synchronised part transfer without requiring a separate cylinder.
Anti-Rotation Web Tracking
The twin-rod geometry prevents piston twisting during stroke, maintaining precise alignment for film or foil edge-guiding systems in packaging lines.
Cam-Driven Sensing
Uses the rear extending rod to physically trigger legacy CS1-B/DS1-B position switches, ideal for tight spaces where barrel-mounted sensors cannot fit.
Replacing the Airtac SUD Series Double Rod Cylinder SUD32X75S with the SAUD32X75S
To replace the discontinued SUD32X75S, specify the SAUD32X75S drop-in: it matches the 32mm bore, 75mm stroke, 1/8 inch port, and FA/LB mounting. When sizing both ways, verify the equal push/pull force of 345N at 0.5MPa fits your load, or step to neighbouring bores (40mm yields 528N) if more force is needed. A double rod is right when you need anti-rotation or a back rod to carry a sensor cam. If using the -S magnet, change legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. For stroke lengths of 300mm or over, confirm the side-load rating of your guide bearings to prevent premature wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD32X75S
- ✓ 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 SUD32X75S FAQ
Yes, the SUD32X75S is discontinued. The exact drop-in replacement is the SAUD32X75S, which offers the same 32mm bore, 75mm stroke, 1/8 inch port, and equal-both-ways force. You only need to upgrade the position sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The SUD32X75S provides equal force both ways: 345N at 0.5MPa, 483N at 0.7MPa, and 621N at 0.9MPa. The air port is 1/8 inch. Because it is double-rod, both faces use the rod-side area, meaning push and pull forces are identical.
