This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X90, 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 SU32X90 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 SAU32X90, which matches its bore, stroke, force and mounting.
The AirTAC SU32X90 is a discontinued double-acting profile-type cylinder with a 32 mm bore and 90 mm stroke, delivering 402 N push force at 0.5 MPa. Because this SU series is end-of-life, AirTAC replaced it with the SAU32X90 direct replacement. You get the exact same extruded aluminium body, 1/8" port, M10x1.25 rod thread and SC-series mounting accessories.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors and a new SAUF built-in 4M solenoid valve variant the SU line lacked. For this non-magnet SKU, no sensor can be fitted.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X90 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 SAU32X90 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×90 | 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 push lightweight machined components out of a fixture on an assembly line.
Short 90 mm stroke actuates a diverter arm to route small boxes at a packaging station without taking up much frame space.
Compact profile body fits between tight uprights to open and close a small gravity feed bin for granular materials.
To replace this discontinued SU32X90, order the SAU32X90 direct equivalent, verifying your 1/8" port, M10x1.25 rod thread, and PT/G/NPT thread choice. Sizing both ways: dropping to a smaller bore loses thrust, while a 40 mm bore offers 628 N push at 0.5 MPa if you need margin. This non-magnet SKU cannot accept a sensor, but if you previously used an SU -S magnet, note the SAU switches to CMSG/DMSG/EMSG sensors. The 21 mm cushions only decelerate the load; for holding a load on air loss, install an external rod lock or pilot-operated check valve. The SAUF valve-integrated option can simplify plumbing if needed.
Replacement checklist
Yes, the SU32X90 is discontinued. The direct replacement is the AirTAC SAU32X90. It matches the 32 mm bore, 90 mm stroke, 402 N force, 1/8" port, and SC-series mounting, so it fits the same application.
The 32 mm bore provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N at 0.9 MPa, and a theoretical max of 82 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot take a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches for its -S versions.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X90 replacement — usually within 7-8 hours.
