This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X175-20, 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 SUJ100X175-20
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X175-20 is a double-acting profile-type standard cylinder with a Ø100mm bore and 175mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X175-20, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X175-20
The AirTAC SUJ100X175-20 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 155-175 mm stroke. The nominal 175 mm is the maximum. It features a 1/2" port, a 25 mm rod, and 29 mm adjustable cushions. The direct replacement is the SAUJ100X175-20, matching the bore, stroke, force, and port.
The stop screw sets the end position but is not a load lock; drift occurs without live air, requiring an external rod lock for holding. The SAUJ upgrade switches legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. Because this specific SKU lacks a magnet, it cannot take a magnetic switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X175-20 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUJ100X175-20 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). |
|---|---|
| 100 | Bore size in mm. |
| ×175 | 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 SUJ100X175-20 Is Used
Press Fit Tuning
Adjusting the extend stop on-site by up to 20 mm to set precise contact pressure for pressing bearings without re-engineering fixed tooling.
Variable Format Sealing
Trimming the 175 mm extend stroke to accommodate different carton depths on a packaging line, ensuring consistent flap closure.
End-of-Line Diverter
Fine-tuning the actuator reach by 20 mm to deflect varying product widths accurately onto downstream routing lanes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X175-20 with the SAUJ100X175-20
To replace the discontinued SUJ100X175-20, specify the SAUJ100X175-20 direct: it retains the 1/2" port, 25 mm rod, 29 mm cushions, and FA/LB mounting. Choose the 20 mm adjust window when you need precise 155-175 mm extend tuning on-site, which often beats installing a fixed SAU plus an external stop. Note that -S sensor versions migrated from CS1-B/DS1-B to CMSG/DMSG/EMSG, though this no-magnet SKU cannot support sensing. For strokes >=300 mm, verify side-load guidance to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X175-20
- ✓ 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 SUJ100X175-20 FAQ
Yes, the SUJ100X175-20 is discontinued. The direct replacement is the SAUJ100X175-20, which matches the 100 mm bore, 175 mm stroke, 1/2" 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 provides a 20 mm adjust window, allowing you to trim the extend stroke from 175 mm down to 155 mm. The stop sets end position and is not a load lock.
