This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X75SN, 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 SU32X75SN 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 direct replacement is the SAU32X75SN, which matches its bore, stroke, force and mounting.
The AirTAC SU32X75SN is a discontinued double-acting profile-type cylinder with a 32mm bore and 75mm stroke. Delivering 402N push at 0.5MPa, its direct replacement is the SAU32X75SN, matching the 1/8" port, M10x1.25 rod thread and SC-series mounting. The extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore.
The NBR (-N) seal suits -20 to +70C. Note the SAU upgrade uses CMSG/DMSG/EMSG sensors instead of this legacy CS1-B/DS1-B magnet, and adds a SAUF valve-integrated option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X75SN carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X75SN produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×75 | 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.
Uses the 402N push force at 0.5MPa to reliably knock small molded parts out of a fixture at the end of a cycle.
Cycles a 75mm stroke to push small components from a sorting chute into a collection bin without occupying much space.
To replace this SU32X75SN, order the SAU32X75SN direct: it preserves the 32mm bore, 75mm stroke, 1/8" port, PT thread and SC mounting. Because your model has the -S magnet, you must switch sensor families from the old CS1-B/DS1-B to the current CMSG/DMSG/EMSG switches. If your application needs true load holding on air loss, note the cushion only decelerates; add an external rod lock or pilot-operated check valve. The NBR seal handles up to 70C. If you need higher force, the neighbouring 40mm bore provides 628N push at 0.5MPa, while downsizing to a 25mm bore drops force significantly.
Replacement checklist
Yes, the SU32X75SN is discontinued. The direct replacement is the AirTAC SAU32X75SN. It shares the exact same 32mm bore, 75mm stroke, 402N output force, 1/8" port and SC-series mounting accessories, so it bolts right in. The only change is that your old CS1-B/DS1-B sensors must be upgraded to CMSG/DMSG/EMSG switches.
The bore is 32mm with a fixed 1/8" port. The output force is 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical maximum of 82kgf at 1.0MPa. The operating speed range is 30-800mm/s.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X75SN replacement — usually within 7-8 hours.
