This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X40, 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 SU32X40
The AirTAC Airtac SU32~50 Standard Cylinder SU32X40 is a double-acting profile-type standard cylinder with a Ø32mm bore and 40mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X40, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X40
The AirTAC SU32X40 is a discontinued double-acting profile-type cylinder with a 32mm bore and 40mm stroke. It delivers 402N push force at 0.5MPa via a 1/8" port. AirTAC replaced this unit with the SAU32X40, a direct alternative retaining the exact bore, stroke, output, and SC-series mounting footprint.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU32X40 upgrade uses current CMSG/DMSG/EMSG switches (the SU line used legacy CS1-B/DS1-B) and introduces the SAUF built-in-valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X40 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 SAU32X40 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.
Where the Airtac SU32~50 Standard Cylinder SU32X40 Is Used
Small Part Ejection
Ideal for pushing lightweight machined components out of a fixture with a quick 40mm stroke and 402N force.
Package Diverting
Actuates a short diverter arm on a packaging line to route small boxes without taking up excessive frame space.
Clamp Actuation
Provides secondary clamping pressure for thin workpieces in assembly jigs where a compact profile body is required.
Replacing the Airtac SU32~50 Standard Cylinder SU32X40 with the SAU32X40
To replace the SU32X40, order the SAU32X40 with the same 32mm bore, 40mm stroke, 1/8" port, and M10x1.25 rod thread. Verify your thread standard (PT/G/NPT) and SC-series mounting brackets (LB/FA/FB/CA/CB). Since this is a non-magnet SKU, it cannot hold a switch; if you need position sensing on the SAU, add the -S suffix and migrate to CMSG/DMSG/EMSG sensors. For higher loads, the adjacent 40mm bore yields 628N push at 0.5MPa. Note that air cushions only decelerate the piston; they do not lock the load. For drop prevention on air loss, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU32X40
- ✓ 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 SU32X40 FAQ
Yes, the SU32X40 is discontinued. The direct replacement is the AirTAC SAU32X40. It matches the 32mm bore, 40mm stroke, 402N force, 1/8" port, and SC-series mounting accessories, so it fits the same application directly.
At 0.5MPa it pushes 402N and pulls 345N; at 0.7MPa it pushes 563N, with a theoretical max of 82kgf at 1.0MPa. This specific SKU has no magnet and cannot take a sensor. The SAU32X40 replacement supports CMSG/DMSG/EMSG switches if you order the -S version.
