This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X180-100, 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 SUJ100X180-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X180-100 is a double-acting profile-type standard cylinder with a Ø100mm bore and 180mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X180-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X180-100
The AirTAC SUJ100X180-100 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 80 to 180 mm stroke. The stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock for held loads.
The direct replacement is the SAUJ100X180-100, retaining the same bore, stroke, force, port, and FA/LB mounting. This base SKU lacks a magnet and cannot take a switch, whereas the SAUJ upgrade path supports modern CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X180-100 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAUJ100X180-100 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 SUJ100X180-100 Is Used
Variable Stroke Pressing
Dial in the exact 80 to 180 mm extend position on-site for pressing assemblies without machining custom spacers.
Adjustable Diverter Arms
Tune the extend stop to accommodate different package sizes on a packaging line without swapping the cylinder.
Positioning Stops
Set precise end positions for pallet routing gates where the required reach varies by pallet depth.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X180-100 with the SAUJ100X180-100
To replace the discontinued SUJ100X180-100, order the direct replacement SAUJ100X180-100, which preserves the 180 mm nominal stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. Because this specific SKU has no magnet, it cannot accept a sensor; if sensing is needed, move to an SAUJ-S variant and use current CMSG/DMSG/EMSG switches rather than the obsolete CS1-B/DS1-B. The 100 mm adjust window is ideal when the final extend position must be dialed in on-site, often beating a fixed SAU plus external stop. For strokes of 300 mm or longer, verify the side-load limits to prevent rod distortion.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X180-100
- ✓ 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 SUJ100X180-100 FAQ
Yes, the SUJ100X180-100 is discontinued. The direct replacement is the SAUJ100X180-100, which matches the 100 mm bore, 180 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also supports the SAUF built-in-valve variant and uses current CMSG/DMSG/EMSG sensors.
The external stop screw lets you trim the extend stroke by up to 100 mm on-site, giving a usable 80 to 180 mm stroke. The stop sets end position only; it is not a load lock.
