This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X300-50S, 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 SUJ32X300-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X300-50S 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 SAUJ32X300-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X300-50S
The AirTAC SUJ32X300-50S is a double-acting, double-rod adjustable-stroke profile cylinder. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable 250 to 300 mm window (the 300 mm nominal stroke is the maximum). The compact extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore.
This SUJ model is discontinued; the direct replacement is the SAUJ32X300-50S, matching the bore, stroke, 50 mm adjust window, force, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B 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 SAUJ32X300-50S 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 SAUJ32X300-50S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SUJ Adjustable Cylinder SUJ32X300-50S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×300 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ32X300-50S Is Used
Variable Depth Diving
Trimming the extend stroke by up to 50 mm on-site allows precise depth control for probing or diving operations without machining custom spacers.
Adjustable Forming Stops
Set the exact 250 to 300 mm end position for material forming or bending tasks where the stop length must be tuned per part batch.
Tunable Reject Pushers
Dial in the push distance on a sorting line to handle varying product sizes, using the external stop to set the exact ejection point.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X300-50S with the SAUJ32X300-50S
To replace the discontinued SUJ32X300-50S, order the direct replacement SAUJ32X300-50S (insert A after the leading S). Choose the 50 mm adjust window when you need on-site extend trimming from 300 mm down to 250 mm. Mounting uses the basic foot FA or LB style, compatible only with AirTAC SC series accessories. Because this is an -S model, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAUJ. At a 300 mm stroke, support the rod with external guides to prevent bending under side loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X300-50S
- ✓ 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 SUJ32X300-50S FAQ
Yes, the SUJ32X300-50S is discontinued. The direct replacement is the SAUJ32X300-50S, which shares the same 32 mm bore, 300 mm stroke, 50 mm adjust window, 1/8" port, and FA/LB mounting. You simply insert an A after the leading S for the new model code.
The external stop screw provides a 50 mm adjust window, allowing you to shorten the extend stroke from the 300 mm maximum down to 250 mm on-site.
