This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X375, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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.

The AirTAC Airtac SU32~50 Standard Cylinder SU32X375 is a double-acting profile-type standard cylinder with a Ø32mm bore and 375mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X375, which matches its bore, stroke, force and mounting.
The AirTAC SU32X375 is a discontinued double-acting profile-type cylinder with a 32mm bore and 375mm stroke. Delivering 402N push at 0.5MPa, it features an extruded aluminum body shorter than ISO 15552 equivalents. AirTAC replaced it with the SAU32X375 direct: identical force, 1/8" port, M10x1.25 rod and SC-series mounts.
This non-magnet SKU cannot take sensors; the SAU upgrade uses CMSG/DMSG/EMSG switches and adds a SAUF valve-integrated option. Note: cushions decelerate only; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X375 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X375 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

|---|---|
| 32 | Bore size in mm. |
| ×375 | 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.
Ejects machined plastic components from a fixture using the 345N pull force at 0.5MPa, relying on the 21mm adjustable cushions for soft stops.
Moves 241N workpiece trays between stations with a compact profile body that saves space compared to standard ISO cylinders of the same bore.
To replace the SU32X375, order the SAU32X375 direct, verifying your 1/8" port, M10x1.25 thread, PT/G/NPT choice and SC-series mounting. Since this 375mm stroke lacks a magnet (-S), it cannot accept sensors. If sensing is needed, the SAU replacement requires CMSG/DMSG/EMSG switches. For sizing both ways: a 40mm bore gives 628N push at 0.5MPa if you need more force, while dropping to a lower pressure reduces wear. At 375mm, prevent rod bending by using an external guide to absorb side loads. For load holding on air loss, add a pilot-operated check valve, as cushions only decelerate.
Replacement checklist
Yes, the SU32X375 is end-of-life. The direct replacement is the AirTAC SAU32X375. It matches the 32mm bore, 375mm stroke, 1/8" port, output force and SC-series mounting accessories, fitting the exact same application.
At 0.5MPa it provides 402N push and 345N pull; 563N push at 0.7MPa; 724N at 0.9MPa; and an 82kgf max at 1.0MPa. This specific SKU has no magnet, so it cannot accept sensors. The SAU replacement supports CMSG/DMSG/EMSG switches if you order the -S version.
