This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X485-50S, 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 SUJ32X485-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X485-50S is a double-acting profile-type standard cylinder with a Ø32mm bore and 485mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X485-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X485-50S
The AirTAC SUJ32X485-50S is a double-acting, double-rod adjustable-stroke profile cylinder. It is discontinued, with the direct replacement being the SAUJ32X485-50S. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable extend range of 435-485 mm (the 485 mm nominal is the maximum). The stop sets the end position but is not a load lock.
The SAUJ upgrade retains the compact profile barrel, bore, stroke, force, and SC-series FA/LB mounts, but switches the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. A plain cylinder drifts on air loss; use an external rod lock for held loads. At 485 mm, external guides are recommended to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X485-50S 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 SAUJ32X485-50S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×485 | 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 SUJ32X485-50S Is Used
Variable Depth Drilling
Adjusting the extend stroke by up to 50 mm on-site allows precise depth control for drilling operations without changing the entire cylinder setup.
Variable Length Diverter
Trimming the extend stroke dynamically accommodates different package sizes on a conveyor line, ensuring accurate sorting without mechanical rebuilds.
Adjustable Stop Positioning
Fine-tuning the end position up to 50 mm provides flexible physical stops for varying pallet dimensions in material handling workflows.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X485-50S with the SAUJ32X485-50S
To replace the discontinued SUJ32X485-50S, order the direct replacement SAUJ32X485-50S, matching the 32 mm bore, 485 mm max stroke, 50 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 50 mm adjust window if your extend stroke needs on-site tuning between 435 and 485 mm; otherwise, a fixed SAU cylinder suffices. Because this model has the -S magnet, upgrade your position sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. At a 485 mm stroke, verify side-load limits and add external guides to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X485-50S
- ✓ 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 SUJ32X485-50S FAQ
Yes, the SUJ32X485-50S is discontinued. The direct replacement is the SAUJ32X485-50S, which matches the 32 mm bore, 485 mm stroke, 50 mm 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 switches.
The external stop screw provides a 50 mm adjust window, allowing the extend stroke to be shortened on-site from the 485 mm maximum down to 435 mm.
