This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X250-75S, 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 SUJ32X250-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X250-75S is a double-acting profile-type standard cylinder with a Ø32mm bore and 250mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X250-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X250-75S
The AirTAC SUJ32X250-75S is a discontinued double-acting double-rod profile cylinder with a 32mm bore and 250mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 75mm on-site, yielding a usable 175-250mm window. This compact extruded barrel is shorter than standard cylinders of the same bore. The 1/8" port and M10x1.25 rod end are fixed by the bore.
Because the SUJ is end-of-life, the direct replacement is the SAUJ32X250-75S, retaining the same force, port, and FA/LB mounting. The SAUJ upgrades sensing to current CMSG/DMSG/EMSG switches, whereas this legacy -S model used CS1-B/DS1-B sensors. Note the stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X250-75S 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 SAUJ32X250-75S 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 SUJ32X250-75S Is Used
Variable Pitch Indexing
Dial in the exact extend stroke on-site to push parts varying distances without swapping the entire cylinder.
Adjustable Diverter Gate
Tune the extend stop to deflect different package sizes on a line, ensuring precise routing without reprogramming.
Crush-Sensitive Forming
Limit the extend stroke to prevent over-compressing delicate materials during packaging operations.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X250-75S with the SAUJ32X250-75S
To replace the discontinued SUJ32X250-75S, order the direct replacement SAUJ32X250-75S, which matches the 32mm bore, 250mm nominal stroke, 75mm adjust window, 1/8" port, and FA/LB mounting. Choose the 75mm adjust window if you need to trim the extend stroke on-site by up to 75mm (usable 175-250mm). For position feedback, swap legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAUJ. Because the stroke is 250mm (>=300mm threshold approaches), verify side-load alignment to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X250-75S
- ✓ 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 SUJ32X250-75S FAQ
Yes, the SUJ32X250-75S is discontinued. The direct replacement is the SAUJ32X250-75S, offering the same 32mm bore, 250mm stroke, 75mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw lets you trim the extend stroke by up to 75mm on-site, giving a usable 175-250mm window. The stop sets end position only and is not a load lock.
