This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X300-30, 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 SUJ32X300-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X300-30 is a double-acting profile-type standard cylinder with a Ø32mm bore and 300mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X300-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X300-30
The AirTAC SUJ32X300-30 is a double-acting double-rod profile cylinder with a 32mm bore and 300mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 30mm on-site, yielding a usable 270-300mm window without changing the physical mount. The stop sets the end position but is not a load lock.
This SUJ model is discontinued; the direct replacement is the SAUJ32X300-30, matching the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches. Note that at 300mm stroke, external guides are recommended to prevent rod bending from side loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X300-30 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 SAUJ32X300-30 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SUJ Adjustable Cylinder SUJ32X300-30 Is Used
Variable Pitch Pushing
Tuning the extend stroke on-site by up to 30mm to push parts of varying widths into a machining station without re-fabricating the entire fixture.
Adjustable Transfer Stops
Setting a precise 270mm to 300mm extend position for diverter gates on a conveyor line to accommodate different package sizes on the fly.
Custom End-of-Stroke Dwell
Trimming the extend stroke by 30mm in testing rigs to alter the dwell position of a pressing or sensing head against a workpiece.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X300-30 with the SAUJ32X300-30
To replace the discontinued SUJ32X300-30, order the direct replacement SAUJ32X300-30, which preserves the 32mm bore, 300mm nominal stroke, 1/8" port, and FA/LB mounting. Choose the 30mm adjust window if your fixture requires field-tuning the extend stroke between 270mm and 300mm. Because this SKU lacks a magnet, it cannot take a switch; if sensing is needed, select the SAUJ with -S and use CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For this 300mm stroke, use external guides to manage side-load and rod-bending risks. The stop screw sets end position only; use an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X300-30
- ✓ 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 SUJ32X300-30 FAQ
Yes, the SUJ32X300-30 is discontinued. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The nominal 300mm extend stroke can be shortened by up to 30mm on-site via the external stop screw, yielding a 270-300mm usable window. The stop sets end position but is not a load lock.
