This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X350-100, 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 SUJ100X350-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X350-100 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 SAUJ100X350-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X350-100
The AirTAC SUJ100X350-100 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 250-350 mm extend window from the 350 mm nominal maximum. The 1/2" port and Ø25 rod are fixed to the 100 mm bore. This SUJ model is discontinued; the direct replacement is the SAUJ100X350-100, matching the bore, stroke, force, port, and FA/LB mounting.
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 SAUJ upgrade retains the compact profile barrel and adopts current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches (this no-magnet SKU cannot take a switch).

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X350-100 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 SAUJ100X350-100 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 SUJ100X350-100 Is Used
Variable Pitch Indexing
Adjusting the extend stroke on-site by up to 100 mm allows a single 350 mm cylinder to drive varying material pitches without swapping the entire actuator.
Variable Height Pallet Stops
The external stop screw sets precise mechanical end positions for different pallet heights, providing a hard physical stop independent of pneumatic pressure.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X350-100 with the SAUJ100X350-100
To replace the discontinued SUJ100X350-100, order the direct replacement SAUJ100X350-100, which preserves the 100 mm bore, 350 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 100 mm adjust window when you need on-site extend trimming between 250 and 350 mm. Because this SKU lacks a magnet, it cannot accept a sensor; if sensing is required, select an SAUJ with the -S suffix and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. At the 350 mm stroke length, minimize side-load and rod-bending by using external guides to support the payload.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X350-100
- ✓ 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 SUJ100X350-100 FAQ
Yes, the SUJ100X350-100 is discontinued. The direct replacement is the SAUJ100X350-100, which matches the 100 mm bore, 350 mm stroke, 100 mm adjust window, 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 allows you to trim the extend stroke by up to 100 mm on-site, giving a usable window of 250-350 mm. The stop sets end position but is not a load lock; use an external rod lock for held loads.
