This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X80-10S, 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 SUJ100X80-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X80-10S 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 SAUJ100X80-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X80-10S
The AirTAC SUJ100X80-10S is a double-acting double-rod adjustable-stroke profile cylinder featuring a 100mm bore and a 1/2 inch port. An external stop screw allows you to trim the extend stroke by up to 10mm on-site, yielding a usable extend range of 70-80mm. The direct replacement is the SAUJ100X80-10S, matching the bore, stroke, force, and SC-series FA/LB mounting.
The stop screw sets the end position but is not a load lock; without live air the piston drifts, so use an external rod lock for held loads. This unit includes a piston magnet for legacy CS1-B/DS1-B switches, whereas the SAUJ replacement upgrades to current CMSG/DMSG/EMSG sensors.

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 SAUJ100X80-10S 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 SUJ100X80-10S Is Used
Press Fit Tuning
Allows operators to dial in the exact 70-80mm extend position on-site for seating bearings without machining fixed stop spacers.
Flight Transfer Stops
Provides a field-adjustable end position to synchronize product push-off distances on packaging lines that handle varying carton lengths.
Pallet Positioning
Offers a 10mm trim window to fine-tune the extend stop for aligning pallets prior to stretch wrapping, ensuring square placement.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X80-10S with the SAUJ100X80-10S
To replace this discontinued SUJ100X80-10S, specify the direct replacement SAUJ100X80-10S, which retains the 100mm bore, 80mm nominal stroke, 10mm adjust window, 1/2 inch port, and FA/LB mounting. Choose the 10mm adjust window when you need precise on-site extend tuning between 70-80mm rather than relying on a fixed stroke. Because this model uses the -S magnet option, you must upgrade from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors on the SAUJ. For strokes of 300mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X80-10S
- ✓ 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 SUJ100X80-10S FAQ
Yes, the SUJ100X80-10S is discontinued. The direct replacement is the SAUJ100X80-10S, which matches the 100mm bore, 80mm stroke, 10mm adjust window, 1/2 inch port, and FA/LB mounting. You only need to upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The external stop screw provides a 10mm adjust window, allowing you to shorten the 80mm extend stroke down to 70mm on-site. The stop sets end position only and does not lock the load.
