This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X350-20S, 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 SUJ100X350-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X350-20S 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 SAUJ100X350-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X350-20S
The AirTAC SUJ100X350-20S is a double-acting double-rod profile cylinder with an on-site stroke-trim window. An external stop screw lets you shorten the extend stroke by up to 20 mm, giving a usable range of 330-350 mm. It features a 1/2" port and M20x1.5 rod thread.
This SUJ unit is discontinued; the direct replacement is the SAUJ100X350-20S, matching the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy model uses CS1-B/DS1-B switches. Note the stop screw sets end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X350-20S 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 SAUJ100X350-20S 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 SUJ100X350-20S Is Used
Variable Stroke Clamping
Adjusts the extend stop on-site to clamp parts of varying heights without reprogramming the motion controller.
Adjustable Diverter Arm
Trims the extend stroke by up to 20 mm to fine-tune a diverting mechanism's reach at the end of a conveyor line.
Variable Depth Stops
Sets precise mechanical end positions for pallets or packages of slightly different depths in a handling cell.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X350-20S with the SAUJ100X350-20S
To replace the discontinued SUJ100X350-20S, order the direct replacement SAUJ100X350-20S, which retains the 100 mm bore, 350 mm stroke, 20 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 20 mm adjust window if you need to trim the extend stroke on-site. Because this is an -S model, you must upgrade from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. For the 350 mm stroke, add external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X350-20S
- ✓ 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 SUJ100X350-20S FAQ
Yes, the SUJ100X350-20S is discontinued. The direct replacement is the SAUJ100X350-20S, offering the same 100 mm bore, 350 mm stroke, 20 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 switches.
The external stop screw window is 20 mm, allowing you to shorten the extend stroke from the 350 mm maximum down to 330 mm. The stop sets end position and is not a load lock.
