This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X350-10S, 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 SUJ100X350-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X350-10S is a double-acting profile-type standard cylinder with a Ø100mm bore and 350mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X350-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X350-10S
The AirTAC SUJ100X350-10S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, giving a usable 340-350 mm stroke. The nominal 350 mm is the maximum. It features a 1/2" port, M20x1.5 rod thread, and 29 mm adjustable cushions. The stop sets the end position but is not a load lock; use an external rod lock for held loads.
This SUJ unit is discontinued; the direct replacement is the SAUJ100X350-10S, matching the bore, stroke, force, port, and FA/LB mounting. The -S suffix means a piston magnet for legacy CS1-B/DS1-B sensors; the SAUJ upgrade uses current CMSG/DMSG/EMSG sensors. With a 350 mm stroke, add external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X350-10S 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 SAUJ100X350-10S 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 SUJ100X350-10S Is Used
Press Fit Tuning
Trimming the extend stroke by up to 10 mm on-site allows precise bottoming force for pressing bearings without machining hard stops.
Divertor Positioning
Field-tuning the 340-350 mm extend stroke lets operators dial in the exact actuation point for moving packages between conveyor lanes.
Pallet Stop Calibration
Adjusting the end position on-site accommodates varying pallet dimensions, ensuring stops align perfectly with the load face.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X350-10S with the SAUJ100X350-10S
To replace the discontinued SUJ100X350-10S, order the direct replacement SAUJ100X350-10S, which retains the 100 mm bore, 350 mm stroke, 10 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 10 mm adjust window when you need fine end-position tuning without adding an external stop. The -S suffix on the new SAUJ requires switching from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. Because the 350 mm stroke exceeds 300 mm, use external guides to manage side-load and prevent rod bending. Note the stop screw sets end position and does not hold loads on air loss; install an external rod lock for vertical holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X350-10S
- ✓ 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 SUJ100X350-10S FAQ
Yes, the SUJ100X350-10S is discontinued. The direct replacement is the SAUJ100X350-10S, which matches the 100 mm bore, 350 mm stroke, 10 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw window is 10 mm, allowing you to shorten the extend stroke from the 350 mm maximum down to 340 mm.
