This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X90S, 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 SU32X90S is a double-acting profile-type standard cylinder with a Ø32mm bore and 90mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X90S, which matches its bore, stroke, force and mounting.
The AirTAC SU32X90S is a discontinued double-acting profile-type cylinder featuring a 32 mm bore, 90 mm stroke, and a built-in piston magnet. It delivers 402 N of push force at 0.5 MPa. AirTAC replaced this unit with the SAU32X90S, a direct alternative retaining the exact same bore, stroke, output force, 1/8" port, and SC-series mounting footprint.
Because of its compact extruded aluminum body, this cylinder is shorter than a standard ISO 15552 unit of the same size. The original -S magnet functioned with legacy CS1-B/DS1-B switches, whereas the modern SAU replacement utilizes current CMSG/DMSG/EMSG sensors.

| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X90S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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.
Actuates a short 90 mm stroke routing arm to sort small boxes on a secondary packaging line.
Secures thin workpieces in an assembly jig where a compact 32 mm profile body is required to avoid tooling interference.
To replace this SU32X90S, order the SAU32X90S and verify your 1/8" port threads (PT, G, or NPT) alongside your SC-series mounting hardware. The transition requires a sensor family change: the original CS1-B/DS1-B switches are superseded by CMSG/DMSG/EMSG sensors on the SAU. If your application needs integrated flow control, the newer SAUF variant includes a built-in 4M solenoid valve the SU line never offered. At 0.5 MPa this 32 mm bore yields 402 N push and 345 N pull; if you need more force, stepping up to a 40 mm bore provides 628 N push. Note that a standard cylinder drifts without live air—the cushions only decelerate the piston, so install an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
Yes, the SU32X90S is discontinued. The direct replacement is the AirTAC SAU32X90S. It matches the 32 mm bore, 90 mm stroke, 402 N force, 1/8" port, and SC-series mounting accessories, so no mechanical redesign is required.
This double-acting cylinder provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa. Because this is an -S model, it has a piston magnet for legacy CS1-B/DS1-B switches; when upgrading to the SAU32X90S, you must switch to the current CMSG/DMSG/EMSG sensor family.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X90S replacement — usually within 7-8 hours.
