This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X180-100S, 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 SUJ100X180-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X180-100S 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 SAUJ100X180-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X180-100S
The AirTAC SUJ100X180-100S is a discontinued double-acting double-rod adjustable-stroke profile cylinder. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 80-180 mm extend range from the 180 mm nominal maximum. The stop screw sets the end position; it is not a load lock.
The direct replacement is the SAUJ100X180-100S, retaining the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S magnet model. A plain cylinder drifts on air loss; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X180-100S 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 SAUJ100X180-100S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SUJ Adjustable Cylinder SUJ100X180-100S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×180 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ100X180-100S Is Used
Variable Depth Forming
Stamping or pressing applications where the material thickness fluctuates, using the 100 mm adjust screw to tune the extend stroke on-site without swapping cylinders.
Adjustable Diverter Arms
Routing different package sizes on a line by trimming the actuator extend stroke from 180 mm down to 80 mm to hit varying lane widths precisely.
Custom Length Pushers
Pushing variable product counts into a cartoning station, dialing in the exact end position via the external stop screw to accommodate different box dimensions.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X180-100S with the SAUJ100X180-100S
To replace the discontinued SUJ100X180-100S, order the direct replacement SAUJ100X180-100S, keeping the 100 mm bore, 180 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounts. Choose the 100 mm adjust window when you need maximum field flexibility to shorten the extend stroke down to 80 mm. For the -S magnet option, swap legacy CS1-B/DS1-B sensors for current CMSG/DMSG/EMSG switches. At 180 mm stroke, side-load is minimal, but for any stroke over 300 mm, verify guide alignment to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X180-100S
- ✓ 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 SUJ100X180-100S FAQ
Yes, the SUJ100X180-100S is discontinued. The direct replacement is the SAUJ100X180-100S, which matches the 100 mm bore, 180 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. You must update your sensors: the SAUJ uses current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B reed sensors.
The external stop screw offers a 100 mm adjust window, allowing you to shorten the 180 mm nominal extend stroke down to 80 mm on-site. The stop sets end position only; it is not a load lock.
