This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X225-100, 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 SUJ100X225-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X225-100 is a double-acting profile-type standard cylinder with a Ø100mm bore and 225mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X225-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X225-100
The AirTAC SUJ100X225-100 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 125-225 mm window. Because this SUJ model is discontinued, the direct replacement is the SAUJ100X225-100, matching the 100 mm bore, 225 mm maximum stroke, 1/2" port, and SC-series FA/LB mounting. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.
This non-magnet SKU cannot take a sensor, and upgrading to the SAUJ moves legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X225-100 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 SAUJ100X225-100 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. |
| ×225 | 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 SUJ100X225-100 Is Used
Variable Pitch Indexing
Trimming the extend stroke by up to 100 mm on-site allows a single 225 mm cylinder to drive multiple product pitches without mechanical rebuilds.
Custom End-Stop Forming
Use the external stop screw to set precise mechanical end positions for pressing or forming tasks, providing a hard physical limit independent of pneumatic pressure.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X225-100 with the SAUJ100X225-100
To replace the discontinued SUJ100X225-100, order the direct replacement SAUJ100X225-100, which preserves the 100 mm bore, 225 mm stroke, 1/2" port, and FA/LB mounts. Choose the 100 mm adjust window if your fixture requires trimming the extend stroke by up to 100 mm on-site. This non-magnet version cannot accept sensors; if you need position detection, select an SAUJ with the -S suffix and use current CMSG/DMSG/EMSG switches. For strokes at or above 300 mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X225-100
- ✓ 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 SUJ100X225-100 FAQ
Yes, the SUJ100X225-100 is discontinued. The direct replacement is the SAUJ100X225-100, which matches the 100 mm bore, 225 mm stroke, 1/2" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw provides a 100 mm adjust window, allowing you to shorten the 225 mm extend stroke down to 125 mm on-site. The stop sets end position but is not a load lock.
