This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X165, 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 SU32X165
The AirTAC Airtac SU32~50 Standard Cylinder SU32X165 is a double-acting profile-type standard cylinder with a Ø32mm bore and 165mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X165, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X165
The AirTAC SU32X165 is a discontinued double-acting profile-type cylinder with a 32mm bore and 165mm stroke. It delivers 402N push force at 0.5MPa via a 1/8" port. AirTAC replaced this with the SAU32X165 direct replacement, retaining the exact bore, stroke, output, port size, and SC-series mounting.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors and a SAUF built-in-valve option the SU lacked. This non-magnet SKU cannot take a switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X165 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 SAU32X165 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 SU32X165 Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably push lightweight machined components out of a fixture during automated machining cycles.
Package Routing
Actuates a 165mm stroke diverter arm to sort small parcels on a conveyor line, benefiting from the compact extruded profile body.
Replacing the Airtac SU32~50 Standard Cylinder SU32X165 with the SAU32X165
To replace this SU32X165, order the SAU32X165. Confirm the 1/8" port, M10x1.25 rod thread, PT/G/NPT thread choice, and SC-series mounting (LB/FA/FB/CA/CB). This SKU lacks a magnet, so it cannot accept a sensor; if sensing is needed, order an SAU32X165-S and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For sizing, a 40mm bore yields 628N push at 0.5MPa, while dropping to lower pressure reduces force. The 21mm cushions only decelerate; use an external rod lock or pilot-operated check valve to hold loads. For the 165mm stroke, guide external rods to prevent side-load bending.
Replacement checklist
- ✓ Same bore / stroke → SAU32X165
- ✓ 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 SU32X165 FAQ
Yes, the AirTAC SU32X165 is discontinued. The direct replacement is the SAU32X165, which shares the same 32mm bore, 165mm stroke, 402N force, 1/8" port, and SC-series mounting.
It provides 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. This specific SKU has no magnet, so it cannot accept a sensor; the SAU-S variant uses CMSG/DMSG/EMSG switches.
