This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X125-10S, 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 SUJ100X125-10S
The AirTAC SUJ Adjustable Cylinder SUJ100X125-10S is a double-acting profile-type standard cylinder with a Ø100mm bore and 125mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X125-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X125-10S
The AirTAC SUJ100X125-10S is a discontinued double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 115-125 mm extend out of the 125 mm nominal maximum. This compact extruded barrel is shorter than an ISO 15552 cylinder of the same bore.
Because the SUJ line is end-of-life, the direct replacement is the SAUJ100X125-10S, which preserves the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors in place of the legacy CS1-B/DS1-B switches used here, and the SAU family adds an SAUF built-in-valve variant the SU line lacked. 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 SAUJ100X125-10S 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 SAUJ100X125-10S 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. |
| ×125 | 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 SUJ100X125-10S Is Used
Press Fit Calibration
Dialing in a precise 115-125 mm extend for seating bearings, where the 10 mm stop screw window absorbs mechanical tolerance stack-up without reprogramming the PLC.
Variable Depth Sealing
Adjusting the extend end position on-site to accommodate different carton depths or flap heights in end-of-line packaging machinery.
Transfer Stop Positioning
Fine-tuning the extend stop point for product diverters or lane guides on a conveyor to handle slight product size variations.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X125-10S with the SAUJ100X125-10S
To replace the discontinued SUJ100X125-10S, specify the direct replacement SAUJ100X125-10S, which matches the 100 mm bore, 125 mm stroke, 10 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 10 mm adjust window if you need precise 115-125 mm extend tuning; for larger trims, select a bigger adjust figure. If your stroke is 300 mm or longer, verify side-load limits to prevent rod deflection. The -S suffix means a piston magnet is present; you must upgrade from legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG switches on the SAUJ. Mounting compatibility is strictly with the AirTAC SC series.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X125-10S
- ✓ 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 SUJ100X125-10S FAQ
Yes, the SUJ100X125-10S is discontinued. The direct replacement is the SAUJ100X125-10S, which preserves the 100 mm bore, 125 mm stroke, 10 mm adjust window, 1/2" port, and FA/LB mounting. You simply upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The external stop screw provides a 10 mm adjust window, allowing you to shorten the 125 mm nominal extend stroke down to 115 mm on-site. The stop sets end position only and does not lock the load.
