This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X225-10, 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 SUJ40X225-10
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X225-10 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 SAUJ40X225-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X225-10
The AirTAC SUJ40X225-10 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 215-225 mm stroke. The nominal 225 mm is the maximum. This compact extruded-aluminum body is shorter than an ISO 15552 cylinder of the same bore.
This SKU has no magnet and cannot take a switch, whereas the SAUJ upgrade supports current CMSG/DMSG/EMSG sensors (the SUJ used legacy CS1-B/DS1-B). The stop screw sets end position but is not a load lock; use an external rod lock for held loads.

|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAUJ40X225-10 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

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 SUJ40X225-10 Is Used
Diverter Gate Positioning
Trimming the extend stroke by up to 10 mm on-site lets operators fine-tune a diverter gate's exact resting angle without machining spacer plates.
Package Stopper Height
A 10 mm external stop adjustment provides quick field tuning of a pneumatic package stop to accommodate varying carton heights on a packing line.
Clamp Closure Tuning
Adjustable end-positioning allows a clamping mechanism to compensate for material thickness variations, ensuring consistent grip without reprogramming.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X225-10 with the SAUJ40X225-10
To replace this discontinued SUJ40X225-10, order the exact SAUJ40X225-10 direct (same 40 mm bore, 225 mm max stroke, 10 mm adjust window, 1/4" port, and FA/LB mounts). The 10 mm adjust window is ideal for minor end-position tuning. Because this specific SKU lacks a magnet, it cannot accept sensors; upgrading to the SAUJ allows using CMSG/DMSG/EMSG switches. For this 225 mm stroke, ensure your load is guided to prevent excessive side-loading. Remember the stop screw is not a lock; add an external rod lock if you need to hold loads on air loss.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X225-10
- ✓ 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 SUJ40X225-10 FAQ
Yes, the SUJ40X225-10 is discontinued. The direct replacement is the SAUJ40X225-10, which matches the 40 mm bore, 225 mm stroke, 1/4" port, and FA/LB mounting. The SAUJ also supports current CMSG/DMSG/EMSG sensors, whereas this SUJ used legacy CS1-B/DS1-B switches.
This double-acting double-rod cylinder has a 10 mm adjustable stroke window (usable extend stroke 215-225 mm; nominal 225 mm is the max). The stop screw sets end position but is not a load lock.
