This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X225-40, 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 SUJ100X225-40
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X225-40 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 SAUJ100X225-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X225-40
The AirTAC SUJ100X225-40 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 185-225 mm stroke from the 225 mm nominal maximum. It features a 100 mm bore, a 25 mm rod, M20x1.5 rod thread, and a 1/2" port. The direct replacement is the SAUJ100X225-40, which matches the bore, stroke, force, port, and FA/LB mounting.
The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used here, and the SAU line adds an SAUF built-in-valve variant the SU series lacked. This SKU has no magnet and cannot take a switch. The stop screw sets end position only; it is not a lock, so add an external rod lock for held loads.

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 SAUJ100X225-40 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 SUJ100X225-40 Is Used
Press Fit Tuning
Adjusting the extend stop on-site by up to 40 mm allows operators to dial in the exact pressing depth for bearings without swapping cylinders.
Variable Format Flap Folding
Carton erectors needing different flap fold positions can trim the 225 mm extend stroke down to 185 mm to accommodate varying box heights quickly.
Adjustable Transfer Stops
Diverting stops on a conveyor can be field-tuned within the 40 mm window to handle mixed product lengths on the same line without reprogramming.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X225-40 with the SAUJ100X225-40
To replace this discontinued SUJ100X225-40, specify the SAUJ100X225-40 direct. It preserves the 100 mm bore, 225 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 40 mm adjust window if you need on-site tuning of the extend end position without machining. Because this SKU lacks a magnet, select the -S suffix on the SAUJ if you require position sensing, and pair it with CMSG/DMSG/EMSG switches. For this 225 mm stroke, side-load is minimal, but for strokes >=300 mm ensure guide alignment to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X225-40
- ✓ 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 SUJ100X225-40 FAQ
Yes, the SUJ100X225-40 is discontinued. The direct replacement is the SAUJ100X225-40, which matches the 100 mm bore, 225 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw provides a 40 mm adjust window, shortening the extend stroke from 225 mm down to 185 mm. The stop sets end position only and is not a load lock.
