This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X300-30S, 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 SUJ32X300-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X300-30S 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 SAUJ32X300-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X300-30S
The AirTAC SUJ32X300-30S is a double-acting double-rod profile cylinder with a 32mm bore and 300mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 30mm on-site, yielding a usable 270-300mm window. This SUJ32X300-30S is discontinued; the direct replacement is the SAUJ32X300-30S.
The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. At 300mm stroke, minimize side-load bending with external guides. The SAUJ upgrade retains the compact profile and FA/LB mounts but switches legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X300-30S 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 SAUJ32X300-30S 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 SUJ32X300-30S Is Used
Variable Pitch Pushing
Tuning the extend stroke by up to 30mm on-site allows a single 300mm cylinder to push parts at varying pitches without swapping the whole actuator.
Adjustable Transfer Stops
An external stop screw provides precise 270-300mm end-position control for diverting different package sizes on a conveyor line.
Custom Depth Ejection
Trimming the extend stroke on-site accommodates varying bin depths, ensuring an ejector rod bottoms out exactly at the required clearance.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X300-30S with the SAUJ32X300-30S
To replace the discontinued SUJ32X300-30S, use the direct replacement SAUJ32X300-30S, which matches the 32mm bore, 300mm stroke, 1/8" port, and FA/LB mounting. Choose the 30mm adjust window if your end-stop needs on-site tuning between 270mm and 300mm. Because this unit has the -S magnet, note that the SAUJ replacement requires current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For this 300mm stroke, verify external guides to prevent rod-bending side loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X300-30S
- ✓ 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 SUJ32X300-30S FAQ
Yes, the SUJ32X300-30S is discontinued. The direct replacement is the SAUJ32X300-30S, offering the same 32mm bore, 300mm stroke, 30mm 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.
The external stop screw trims the extend stroke by up to 30mm, giving a usable 270-300mm window. The stop sets end position but is not a load lock.
