This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X225-10S, 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 SUJ40X225-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X225-10S is a double-acting profile-type standard cylinder with a Ø40mm bore and 225mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X225-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X225-10S
The AirTAC SUJ40X225-10S is a 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 215-225 mm extension out of the 225 mm nominal maximum. This compact extruded-aluminum body is shorter than a standard ISO 15552 unit of the same bore and features a 1/4" port, a 16 mm rod, and adjustable 21 mm cushions. It is discontinued and replaced directly by the SAUJ40X225-10S.
Note the stop screw sets end position only; it is not a load lock. The legacy CS1-B/DS1-B sensors on this -S model are superseded by CMSG/DMSG/EMSG switches on the SAUJ.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X225-10S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAUJ40X225-10S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 40 | 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 SUJ40X225-10S Is Used
End-Position Trimming
Ideal for assembly stations needing precise 215-225 mm extend endpoints to accommodate minor part tolerances without re-engineering the entire fixture.
Reject Diverter Setup
Provides adjustable reach on a 225 mm stroke to fine-tune the pusher angle and contact point when diverting varying package widths on a line.
Carton Forming Stops
Allows on-site stroke reduction to dial in the exact folding contact point for carton erecting, preventing over-travel and crushing.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X225-10S with the SAUJ40X225-10S
To replace the discontinued SUJ40X225-10S, specify the SAUJ40X225-10S as a direct, matching the 40 mm bore, 225 mm stroke, 10 mm adjust window, 1/4" port, and FA/LB mounting. Choose the 10 mm adjust window when you need minor field tuning of the extend end-position. Because this -S model has a piston magnet, you must upgrade from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For stroke lengths of 300 mm or greater, carefully verify side-load limits to prevent rod binding. The stop screw is not a lock; for held loads, add an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X225-10S
- ✓ 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 SUJ40X225-10S FAQ
Yes, the SUJ40X225-10S is discontinued. The direct replacement is the SAUJ40X225-10S, which shares the same 40 mm bore, 225 mm stroke, 10 mm adjust window, 1/4" port, and FA/LB mounting. You only need to upgrade the position sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The external stop screw provides a 10 mm adjustment window, allowing you to shorten the 225 mm nominal extend stroke down to 215 mm on-site. The stop sets end position only and is not a load lock.
