This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X475S, 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.
Airtac SU32~50 Standard Cylinder SU32X475S
The AirTAC SU32~50 Standard Cylinder SU32X475S is a double-acting profile-type standard cylinder with a Ø32mm bore and 475mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X475S, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X475S
The AirTAC SU32X475S is a discontinued double-acting profile-type cylinder with a 32 mm bore and 475 mm stroke. It delivers 402 N push force at 0.5 MPa through a 1/8" port. AirTAC replaced this unit with the SAU32X475S, a direct replacement sharing the exact same extruded body dimensions, output force, and SC-series mounting accessories.
When upgrading, note that your legacy CS1-B/DS1-B switches are replaced by modern CMSG/DMSG/EMSG sensors on the SAU. The original SU line never offered a valve-integrated body, but the SAU family adds an optional SAUF variant with a built-in 4M solenoid.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X475S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X475S 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.
Where the Airtac SU32~50 Standard Cylinder SU32X475S Is Used
Compact Assembly Ejector
Ejects small finished parts from a tight machine cell where an ISO 15552 cylinder would take up too much envelope space, benefiting from the shorter profile body.
Replacing the Airtac SU32~50 Standard Cylinder SU32X475S with the SAU32X475S
To replace this SU32X475S, order the SAU32X475S and confirm your 1/8" port, M10x1.25 rod thread, and SC-series mounting (LB/FA/FB/CA/CB). Because this SKU includes the -S magnet, you must swap your legacy CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors. At 475 mm stroke, the 12 mm rod is susceptible to bending under side loads—always use external guides to prevent premature seal wear. For higher force needs, step up to a 40 mm bore (628 N push @0.5 MPa); for lighter duties, verify your load stays above the safe working threshold of 241 N. Remember that a standard cylinder drifts without live air; install an external rod lock or pilot-operated check valve if the load must be held vertically.
Replacement checklist
- ✓ Same bore / stroke → SAU32X475S
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SU32~50 Standard Cylinder SU32X475S FAQ
Yes, the SU32X475S is discontinued. The direct replacement is the AirTAC SAU32X475S. It matches the 32 mm bore, 475 mm stroke, 402 N push force at 0.5 MPa, 1/8" port, and SC-series mounting. You simply order the SAU equivalent.
The 32 mm bore provides 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a maximum theoretical force of 82 kgf at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are obsolete; the SAU replacement requires CMSG, DMSG, or EMSG sensors.
