This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X225-75S, 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 SUJ32X225-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X225-75S 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 SAUJ32X225-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X225-75S
The AirTAC SUJ32X225-75S is a discontinued double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 150-225 mm extend out of the 225 mm nominal maximum.
The direct replacement is the SAUJ32X225-75S, matching the bore, stroke, force, port, and FA/LB mounting. Upgrading to the SAUJ family moves you from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. 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 SAUJ32X225-75S 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 SAUJ32X225-75S 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 SUJ32X225-75S Is Used
Adjustable End-Stop Forming
Dialing in a precise 150-225 mm extend for light stamping or pressing tasks where the final contact position must be tuned on-site for different material thicknesses.
Variable-Length Diverter
Actuating a sorting gate where the extend stroke needs field adjustment up to 75 mm to accommodate changing package sizes on the fly without swapping cylinders.
Custom Pusher Stroke
Positioning items on a roller bed by trimming the extend stroke to exact product dimensions, preventing over-travel and damage in compact packaging cells.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X225-75S with the SAUJ32X225-75S
To replace this discontinued SUJ32X225-75S, order the direct replacement SAUJ32X225-75S. The 75 mm adjust window is ideal for dialing in the 150-225 mm extend stroke on-site without machining external stops. Retain FA or LB mounting from the SC series. Because this is an -S model, note the sensor transition from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG on the SAUJ. For this 225 mm stroke, verify side-load alignment to prevent rod binding. Remember the stop screw sets position only; it does not lock the load on air loss.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X225-75S
- ✓ 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 SUJ32X225-75S FAQ
Yes, the SUJ32X225-75S is discontinued. The direct replacement is the SAUJ32X225-75S, which matches the 32 mm bore, 225 mm stroke, 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 allows you to trim the extend stroke by up to 75 mm on-site, giving a usable extend range of 150-225 mm. The stop sets end position and is not a load lock.
