This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X120-50S, 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 SUJ32X120-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X120-50S 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 SAUJ32X120-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X120-50S
The AirTAC SUJ32X120-50S is a discontinued double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 70-120 mm extend out of the 120 mm nominal maximum.
Because this model is end-of-life, the direct replacement is the SAUJ32X120-50S, which preserves the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades the sensor suite to current CMSG/DMSG/EMSG switches (this -S unit used legacy CS1-B/DS1-B). 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 SAUJ32X120-50S 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 SAUJ32X120-50S 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 SUJ32X120-50S Is Used
Variable Pitch Indexing
Dialing the extend stroke on-site by up to 50 mm allows a single 32 mm bore cylinder to drive multiple part pitches without swapping the whole actuator.
Adjustable Reject Pusher
Trimming the extend stroke lets a reject arm reach different product widths on the fly, using the 1/8" ported body to clear varying package sizes.
Tunable Diverter Gate
Field-adjusting the 120 mm maximum stroke by 50 mm sets the exact gate open angle for diverting mixed product types without re-engineering the mount.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X120-50S with the SAUJ32X120-50S
To replace the discontinued SUJ32X120-50S, order the direct replacement SAUJ32X120-50S, which matches the 32 mm bore, 120 mm max stroke, 1/8" port, and FA/LB mounting. The 50 mm adjust window is ideal if your end-stop varies by up to 50 mm; if you need less on-site trim, a smaller adjust figure simplifies tuning. Because this has the -S magnet, swap the legacy CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors on the SAUJ. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding. The stop screw sets end position but does not hold the load on air loss—add an external rod lock for vertical holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X120-50S
- ✓ 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 SUJ32X120-50S FAQ
Yes, the SUJ32X120-50S is discontinued. The direct replacement is the SAUJ32X120-50S, which matches the 32 mm bore, 120 mm stroke, 1/8" port, and FA/LB mounting. You must upgrade the switches from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.
The external stop screw provides a 50 mm adjust window, allowing you to shorten the 120 mm nominal extend stroke down to 70 mm on-site. The stop sets end position and is not a load lock.
