This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X80S, 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 SU32~50 Standard Cylinder SU32X80S is a double-acting profile-type standard cylinder with a Ø32mm bore and 80mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X80S, which matches its bore, stroke, force and mounting.
The AirTAC SU32X80S is a discontinued double-acting profile-type cylinder with an 80 mm stroke and 32 mm bore. Delivering 402 N push at 0.5 MPa, its extruded aluminum body is more compact than an ISO 15552 unit of the same size. AirTAC replaced it with the SAU32X80S direct replacement: identical bore, stroke, force, 1/8" port, and SC-series mounting.
This -S SKU includes a piston magnet for legacy CS1-B/DS1-B switches; the SAU successor upgrades to CMSG/DMSG/EMSG sensors and adds a SAUF valve-integrated variant the SU line lacked. A plain cylinder drifts without live air, so use an external rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X80S 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 SAU32X80S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×80 | 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 402 N push force at 0.5 MPa to reliably knock lightweight molded parts out of a fixture on an injection molding line.
Actuates a short 80 mm stroke routing arm to push small cartons off a main conveyor belt into a packing chute.
Provides compact horizontal selection of small electronic components on a test tray, fitting neatly within tight machine envelopes.
To replace this discontinued SU32X80S, order the SAU32X80S direct equivalent, verifying the 32 mm bore, 80 mm stroke, 1/8" port, M10x1.25 rod thread, and SC-series mounting. Because this is an -S magnet model, note the sensor family changes from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. If you need higher force, the neighboring 40 mm bore yields 628 N push at 0.5 MPa; if lower force is acceptable, check smaller options. For load holding, remember the air cushion only decelerates at stroke end and the piston drifts without air pressure—install a pilot-operated check valve or rod lock. If your application needs self-switching, explore the SAUF built-in 4M solenoid valve variant.
Replacement checklist
Yes, the SU32X80S is discontinued. The direct replacement is the AirTAC SAU32X80S. It shares the same 32 mm bore, 80 mm stroke, output force, 1/8" port, and SC-series mounting accessories, so it fits the same application directly.
The 32 mm bore delivers 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. This -S model has a magnet for legacy CS1-B/DS1-B switches; the SAU replacement requires current CMSG/DMSG/EMSG sensors.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X80S replacement — usually within 7-8 hours.
