This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X80-40, 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 SUJ100X80-40
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X80-40 is a double-acting profile-type standard cylinder with a Ø100mm bore and 80mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X80-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X80-40
The AirTAC SUJ100X80-40 is a double-acting double-rod profile cylinder with an adjustable stroke, letting you trim the extend stroke by up to 40 mm on-site (usable extend 40-80 mm). The direct replacement is the SAUJ100X80-40, matching the 100 mm bore, 80 mm stroke, 1/2" port, and 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 switch. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors, whereas this SUJ used legacy CS1-B/DS1-B.

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 SUJ100X80-40 Is Used
Variable Stroke Pressing
Dial in the exact 40-80 mm extend contact point for light assembly presses without swapping cylinders.
Adjustable Diverter Arms
Tune the extend stop on-site to route different package sizes on a packaging line.
Variable Position Stops
Set precise end positions for pallet stops where the nominal 80 mm stroke needs trimming.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X80-40 with the SAUJ100X80-40
To replace the discontinued SUJ100X80-40, order the SAUJ100X80-40 direct, which preserves the 1/2" port, M20x1.5 rod thread, and 29 mm cushions. Choose the 40 mm adjust window if you need field tuning between 40 and 80 mm. It uses FA or LB mounting (SC-series compatible only). Because this SKU lacks a magnet, it cannot take sensors; the SAUJ uses CMSG/DMSG/EMSG switches. For strokes >=300 mm, verify side-load guidance.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X80-40
- ✓ 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 SUJ100X80-40 FAQ
Yes, the SUJ100X80-40 is discontinued. The direct replacement is the SAUJ100X80-40, offering the same 100 mm bore, 80 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting.
It is double-acting double-rod. The external stop screw shortens the extend stroke by up to 40 mm (usable 40-80 mm). The stop sets end position, not a load lock.
