This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X455S, 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 SU32X455S is a double-acting profile-type standard cylinder with a Ø32mm bore and 455mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X455S, which matches its bore, stroke, force and mounting.
The AirTAC SU32X455S is a discontinued double-acting profile cylinder with a 32mm bore and 455mm stroke. Delivering 402N push force at 0.5MPa via a 1/8 port, its direct replacement is the SAU32X455S, matching the body, force, and SC-series mounts.
The SAU upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S model, and adds a SAUF built-in valve option. The 455mm stroke requires external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X455S 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 SAU32X455S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×455 | 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 molded plastic parts from a machine bed, where the compact profile body saves space and the 1/8 port delivers rapid actuation.
Sorts lightweight goods into chutes, requiring external guides to prevent side-load bending over the 455mm travel.
To replace this SU32X455S, order the SAU32X455S direct equivalent, confirming the 1/8 port, M10x1.25 rod thread, and SC-series mounting. If sizing alternatives, a 40mm bore yields 628N push at 0.5MPa, while dropping pressure below 0.5MPa reduces the 402N output. The -S magnet requires switching to CMSG/DMSG/EMSG sensors on the SAU. For the 455mm stroke, use external guides to prevent rod bending. The cylinder will not hold a load without air; use a pilot-operated check valve or rod lock. The SAUF variant offers a built-in valve if needed.
Replacement checklist
Yes, the SU32X455S is discontinued. The direct replacement is the SAU32X455S, offering the same 32mm bore, 455mm stroke, 402N force, 1/8 port, and SC-series mounting compatibility.
It delivers 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. The -S magnet worked with legacy CS1-B/DS1-B switches, but the SAU replacement requires CMSG/DMSG/EMSG sensors.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU32X455S replacement — usually within 7-8 hours.
