This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X140, 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 SU32X140
The AirTAC SU32~50 Standard Cylinder SU32X140 is a double-acting profile-type standard cylinder with a Ø32mm bore and 140mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X140, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X140
The AirTAC SU32X140 is a discontinued double-acting profile cylinder with a 32 mm bore and 140 mm stroke. It delivers 402 N push force at 0.5 MPa through a 1/8" port. AirTAC replaced this legacy unit with the SAU32X140, a direct alternative retaining the exact bore, stroke, output force, port size and SC-series mounting.
Because this is a non-magnet SKU, it cannot accept a sensor. The SAU upgrade introduces current CMSG/DMSG/EMSG switches for its -S variants and a SAUF built-in-valve option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X140 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 SAU32X140 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. |
| ×140 | 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.
Where the Airtac SU32~50 Standard Cylinder SU32X140 Is Used
Small Part Ejection
Uses the 402 N push force at 0.5 MPa to reliably push lightweight machined components out of a fixture on an automated line.
Package Diverting
Actuates a short-stroke gate to sort small cartons on a conveyor, taking advantage of the compact 32 mm profile body.
Replacing the Airtac SU32~50 Standard Cylinder SU32X140 with the SAU32X140
To replace the SU32X140, order the SAU32X140. Verify your 1/8" port thread (PT, G or NPT) and SC-series mounting (LB, FA, FB, CA, CB or TC). This non-magnet SKU cannot hold a position switch. If you need sensing on the new SAU, select the -S option and use CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. The 32 mm bore yields 402 N push at 0.5 MPa; if undersized, the 40 mm bore offers 628 N. A plain cylinder drifts on air loss, so add an external rod lock or pilot-operated check valve for load holding. The 140 mm stroke is below the 300 mm threshold, so rod bending is minimal, but ensure adequate side-load guidance.
Replacement checklist
- ✓ Same bore / stroke → SAU32X140
- ✓ 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 SU32X140 FAQ
Yes, the AirTAC SU32X140 is discontinued. The direct replacement is the SAU32X140. It shares the same 32 mm bore, 140 mm stroke, 402 N output force at 0.5 MPa, 1/8" port, and SC-series mounting accessories, so it fits the same application directly.
The 32 mm bore generates 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a theoretical max of 82 kgf at 1.0 MPa. This specific non-magnet SKU cannot accept a sensor; if you need position detection on the SAU replacement, you must order an -S version and use CMSG/DMSG/EMSG switches.
