This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X80-30, 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 SUJ100X80-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X80-30 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 SAUJ100X80-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X80-30
The AirTAC SUJ100X80-30 is a discontinued double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 50-80 mm extend from the 80 mm nominal maximum. Bore is 100 mm, port is 1/2", and the rod is Ø25 mm with an M20x1.5 thread. This SKU has no magnet and cannot take a switch.
The direct replacement is the SAUJ100X80-30, matching the bore, stroke, 30 mm adjust window, force, and FA/LB mounting. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. The stop screw sets end position only; it is not a load lock, so use 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 SAUJ100X80-30 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 SUJ100X80-30 Is Used
Press Fit Tuning
Allows operators to dial in the exact 50-80 mm extend distance on-site for inserting parts without re-engineering the entire fixture.
Variable Length Diverter
Adjusts the extend stop in real time to accommodate different package sizes on a packaging line without changing out cylinders.
Adjustable End Stop Pusher
Provides a field-tuned end position for pushing pallets or containers, ensuring precise placement regardless of load variations.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X80-30 with the SAUJ100X80-30
To replace the discontinued SUJ100X80-30, order the direct replacement SAUJ100X80-30, which preserves the 100 mm bore, 80 mm nominal stroke, 30 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 30 mm adjust window when you need field tuning between 50 and 80 mm; a fixed SAU plus external stop is bulkier. Because this SKU lacks a magnet, it cannot take a switch; the SAUJ upgrade uses CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes at or above 300 mm, verify side-load limits. The stop screw sets end position and is not a load lock—add an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X80-30
- ✓ 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
