This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X120-30S, 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 SUJ32X120-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X120-30S is a double-acting profile-type standard cylinder with a Ø32mm bore and 120mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X120-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X120-30S
The AirTAC SUJ32X120-30S is a discontinued double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, giving a usable extend range of 90-120 mm from the 120 mm nominal maximum. The stop screw sets the end position but is not a load lock.
Because the SUJ32X120-30S is end-of-life, the direct replacement is the SAUJ32X120-30S, keeping the same bore, stroke, force, 1/8" port and SC-series FA/LB mounting. Upgrading to the SAUJ moves the piston magnet to current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here. The compact extruded aluminum barrel is shorter than a standard cylinder of the same bore, making it ideal for tight machine envelopes.

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 SAUJ32X120-30S 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 SUJ32X120-30S Is Used
Probe Contact Tuning
Trimming the extend stroke by up to 30 mm on-site allows precise contact force adjustment for pneumatic testing probes without machining custom spacers.
Variable Length Diverter
Adjusting the extend stop on the fly accommodates different package sizes on a conveyor diverter arm, ensuring accurate routing without changing cylinders.
Adjustable Pusher Stroke
Setting a shorter extend end position handles varying product widths at a packing station pusher, preventing crushing while maintaining cycle speed.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X120-30S with the SAUJ32X120-30S
To replace the discontinued SUJ32X120-30S, order the direct replacement SAUJ32X120-30S, which preserves the 32 mm bore, 120 mm stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 30 mm adjust window if you need to fine-tune the extend stroke between 90 and 120 mm on-site, which often beats installing a fixed cylinder plus an external stop. If your stroke is 300 mm or longer, verify the rod side-load limits to prevent excessive wear. Because this is an -S model, note the sensor change: the SAUJ uses current CMSG/DMSG/EMSG switches, whereas this SUJ uses legacy CS1-B/DS1-B switches. For any load-holding requirement, add an external rod lock or pilot-operated check valve, as the adjust screw and air cushions only set position and decelerate, never lock the load on air loss.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X120-30S
- ✓ 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 SUJ32X120-30S FAQ
Yes, the SUJ32X120-30S is discontinued. The direct replacement is the SAUJ32X120-30S, which matches the 32 mm bore, 120 mm stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ also upgrades the magnet to current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw provides a 30 mm adjust window, allowing you to shorten the 120 mm nominal extend stroke down to 90 mm on-site. The stop sets end position and is not a load lock.
