This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X350-100S, 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.

The AirTAC SUJ Adjustable Cylinder SUJ100X350-100S 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 SAUJ100X350-100S, which matches its bore, stroke, force and mounting.
The AirTAC SUJ100X350-100S is a discontinued double-acting double-rod profile cylinder with a 100mm bore, 350mm nominal stroke, and a built-in piston magnet. An external stop screw lets you trim the extend stroke by up to 100mm on-site, yielding a usable 250-350mm extension. The stop sets the end position but is not a load lock.
The direct replacement is the SAUJ100X350-100S, matching 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 model. A plain cylinder drifts on air loss; use an external rod lock for held loads.

The SAUJ100X350-100S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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.
Field-tune the extend stroke from 250 to 350mm on-site to press components of varying heights without swapping the entire cylinder.
Trim the actuation length by up to 100mm to reposition a sorting diverter for different package sizes on a moving line.
Set precise 250-350mm extend endpoints for pallet positioning racks where the required reach changes between production runs.
To replace the discontinued SUJ100X350-100S, order the direct replacement SAUJ100X350-100S, which preserves the 100mm bore, 350mm stroke, 1/2" port, M20x1.5 rod thread, and FA/LB mounting. The SAUJ also introduces the SAUF built-in-valve variant. Choose the 100mm adjust window if your field stroke tuning requires trimming the full 100mm; smaller windows save space. For the -S magnet, swap legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches. At 350mm stroke, support the rod against side-load bending with external guides. The stop screw sets end position only; add a pilot-operated check valve or external rod lock if the load must be held.
Replacement checklist
Yes, the AirTAC SUJ100X350-100S is discontinued. The direct replacement is the SAUJ100X350-100S, 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 switches.
The external stop screw window is 100mm, allowing you to trim the extend stroke from the 350mm maximum down to 250mm on-site. The stop sets end position only and is not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAUJ100X350-100S replacement — usually within 7-8 hours.
