This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X225-40S, 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 SUJ Adjustable Cylinder SUJ32X225-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X225-40S is a double-acting profile-type standard cylinder with a Ø32mm bore and 225mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X225-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X225-40S
The AirTAC SUJ32X225-40S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 185-225 mm range from the 225 mm nominal maximum.
The direct replacement is the SAUJ32X225-40S, retaining the exact bore, stroke, force, port, and FA/LB mounting. Upgrading to the SAUJ moves you to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B switches on this -S model. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X225-40S 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 SAUJ32X225-40S 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 SUJ Adjustable Cylinder SUJ32X225-40S Is Used
Variable Pitch Pushing
Feeding different length blanks on a single line by dialing the extend stroke down 40 mm on-site without swapping the cylinder.
Adjustable Divert Stops
Tuning the stop position for changing package sizes on a conveyor, using the external screw to set the exact 185-225 mm extend endpoint.
Flexible End-of-Line Stops
Modifying part ejection distance at packaging stations quickly to handle varied carton footprints without re-mounting hardware.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X225-40S with the SAUJ32X225-40S
To replace the discontinued SUJ32X225-40S, order the direct replacement SAUJ32X225-40S, which matches the 32 mm bore, 225 mm stroke, 40 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 40 mm adjust window if your fixture requires trimming the extend stroke between 185 and 225 mm on-site; the stop screw sets end position but does not lock the load. Because this -S model uses legacy CS1-B/DS1-B switches, you must migrate to CMSG/DMSG/EMSG sensors on the SAUJ. For this 225 mm stroke, confirm side-load limits on the rod end to prevent premature seal wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X225-40S
- ✓ 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 SUJ Adjustable Cylinder SUJ32X225-40S FAQ
Yes, the SUJ32X225-40S is discontinued. The direct replacement is the SAUJ32X225-40S, matching the 32 mm bore, 225 mm stroke, 40 mm adjust window, 1/8" port, and FA/LB mounting. You will need to upgrade from the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The external stop screw trims the extend stroke by up to 40 mm on-site, giving a usable 185-225 mm range from the 225 mm maximum. The screw sets end position only and is not a load lock.
