This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X80-75, 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 SUJ100X80-75
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X80-75 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 SAUJ100X80-75, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X80-75
The AirTAC SUJ100X80-75 is a double-acting double-rod profile cylinder with an adjustable extend stroke, allowing you to trim the 80 mm nominal stroke by up to 75 mm on-site for a usable 5-80 mm window. It features a 1/2" port, an M20x1.5 rod thread, and 29 mm adjustable cushions. The direct replacement is the SAUJ100X80-75, sharing the same force, mounting, and porting.
Two key upgrade notes: the SAUJ successor uses current CMSG/DMSG/EMSG sensors whereas this SUJ used legacy CS1-B/DS1-B units, and its compact profile barrel is shorter than an ISO 15552 cylinder. The external stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, 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 SAUJ100X80-75 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 SUJ100X80-75 Is Used
Variable Depth Forming
Pressing or forming parts to different depths on a single fixture by dialing the extend stroke down from 80 mm to as little as 5 mm via the external stop.
Adjustable Transfer Stops
Acting as a lane diverter or stopper on a conveyor where product lengths vary, allowing operators to tune the protrusion distance on-site without changing cylinders.
Variable Height Ejection
Ejecting parts from a machine bed into bins of varying heights, using the 75 mm adjust window to set the exact ejection reach for each batch.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X80-75 with the SAUJ100X80-75
To replace the discontinued SUJ100X80-75, order the SAUJ100X80-75 direct (insert A after the leading S). It retains the 100 mm bore, 80 mm stroke, 75 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 75 mm adjust window when you need field stroke tuning between 5 and 80 mm. Because this SKU lacks a magnet (-S), it cannot take a switch; the SAUJ with -S uses CMSG/DMSG/EMSG sensors. For strokes at or over 300 mm, verify your side-load limits. The stop screw sets end position only—it is not a lock, so use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X80-75
- ✓ 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 SUJ100X80-75 FAQ
Yes, the AirTAC SUJ100X80-75 is discontinued. The direct replacement is the SAUJ100X80-75, which matches the 100 mm bore, 80 mm stroke, 75 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also supports the current CMSG/DMSG/EMSG sensors and the SAUF built-in-valve variant.
This double-acting double-rod cylinder has a 75 mm adjust window, yielding a usable extend stroke of 5-80 mm from the 80 mm nominal maximum. It uses a 1/2" port and 29 mm cushions.
