This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X500S, 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 SU32X500S is a double-acting profile-type standard cylinder with a Ø32mm bore and 500mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X500S, which matches its bore, stroke, force and mounting.
The AirTAC SU32X500S is a discontinued double-acting profile-type cylinder with a 32mm bore and 500mm stroke. Delivering 402N push force at 0.5MPa via a 1/8" port, its extruded aluminum body is more compact than an ISO 15552 unit of the same bore. AirTAC replaced it with the SAU32X500S direct replacement, retaining the exact bore, stroke, force, port and SC-series mounting.
The SAU upgrade switches the legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors, and introduces the SAUF built-in valve option the SU line lacked. Note that a 500mm stroke risks rod bending under side loads, requiring external guides.

| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X500S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

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 eject small machined parts from a fixture, relying on the 500mm stroke to clear the work area completely.
Actuates a diverter arm over a 500mm distance to route lightweight packages, taking advantage of the compact 32mm profile body to fit tight transfer spaces.
To replace this SU32X500S, order the SAU32X500S direct equivalent, verifying the 32mm bore, 500mm stroke, 1/8" port, M10x1.25 rod thread and SC-series mounting. Because this SKU has the -S magnet, you must upgrade your legacy CS1-B/DS1-B switches to the SAU-compatible CMSG/DMSG/EMSG family. For higher force needs, consider the 40mm bore (628N push @0.5MPa); for tighter spaces, the 25mm bore offers less force. At 500mm stroke, prevent rod bending by adding external guides to absorb side loads. The cylinder will not hold a load without live air—use an external rod lock or pilot-operated check valve for secure holding. The SAUF variant adds a built-in 4M solenoid valve if you need self-switching.
Replacement checklist
Yes, the AirTAC SU32X500S is discontinued and end-of-life. The direct replacement is the SAU32X500S. It shares the identical 32mm bore, 500mm stroke, 402N force, 1/8" port and SC-series mounting accessories, so it fits the same application directly.
The SAU32X500S provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and an 82kgf theoretical max at 1.0MPa. Because your SU model has the -S magnet, the legacy CS1-B/DS1-B switches are obsolete; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
