This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X350-40, 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 SUJ100X350-40
The AirTAC SUJ Adjustable Cylinder SUJ100X350-40 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 SAUJ100X350-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X350-40
The AirTAC SUJ100X350-40 is a double-acting double-rod adjustable-stroke profile cylinder, now discontinued. The direct replacement is the SAUJ100X350-40, matching the 100mm bore, 350mm nominal stroke, 1/2" port, and SC-series mounting. An external stop screw lets you trim the extend stroke by up to 40mm on-site, yielding a usable 310-350mm stroke. The stop sets the end position but is not a load lock.
The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of legacy CS1-B/DS1-B. Note this SKU lacks a magnet, so it cannot take a switch. 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 SAUJ100X350-40 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 SAUJ100X350-40 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 SUJ100X350-40 Is Used
Variable Pitch Indexing
Trimming the 350mm extend stroke by up to 40mm on-site allows a single profile cylinder to drive multiple varying pitch lengths without swapping the entire actuator.
Adjustable Transfer Pusher
Field-tune the extend stop to 310mm for smaller pallets or extend to the full 350mm maximum for larger loads, accommodating changing line formats quickly.
Packaging Flap Folding
Dial in the exact 40mm stroke reduction needed to fold varying carton depths precisely, using the external stop screw to set the final end position.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X350-40 with the SAUJ100X350-40
To replace the discontinued SUJ100X350-40, order the direct replacement SAUJ100X350-40. Choose the 40mm adjust window if your end-stop needs field tuning between 310-350mm. Mounting uses FA or LB brackets (SC-series only). Because this SKU has no magnet, it cannot accept a sensor; the SAUJ upgrade requires CMSG/DMSG/EMSG switches. For the 350mm stroke, add external guides to prevent rod bending and side-load wear. The adjuster sets end position, not a lock—add a pilot-operated check valve or external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X350-40
- ✓ 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 SUJ100X350-40 FAQ
Yes, the SUJ100X350-40 is discontinued. The direct replacement is the SAUJ100X350-40, which matches the 100mm bore, 350mm stroke, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw window is 40mm, meaning you can shorten the 350mm extend stroke down to 310mm on-site. The stop sets end position and is not a load lock.
