This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X75-40S, 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 SUJ100X75-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X75-40S is a double-acting profile-type standard cylinder with a Ø100mm bore and 75mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X75-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X75-40S
The AirTAC SUJ100X75-40S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 35-75 mm stroke from the 75 mm nominal maximum. It features a 1/2" port, a 25 mm rod, and 29 mm adjustable air cushions. This discontinued unit is fully replaced by the SAUJ100X75-40S, retaining the exact bore, 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 keeps the compact profile body but switches the -S magnet sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X75-40S 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 SAUJ100X75-40S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 100 | Bore size in mm. |
| ×75 | Stroke length in mm. |
| -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.
Where the Airtac SUJ Adjustable Cylinder SUJ100X75-40S Is Used
Custom Press Stroke Tuning
Ideal for light pressing tasks where the exact end position must be dialed in on the machine, using the 40 mm stop screw to compensate for material thickness variations.
Variable Length Diverter
Allows operators to shorten the extend stroke on-site to accommodate different package sizes on a sorting line without swapping the entire cylinder.
Adjustable Stop Positioning
Perfect for pallet handling where the extend stop point needs field adjustment to safely interface with varying pallet heights and geometries.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X75-40S with the SAUJ100X75-40S
To replace the discontinued SUJ100X75-40S, order the direct replacement SAUJ100X75-40S, which matches the 100 mm bore, 75 mm nominal stroke, 40 mm adjust window, 1/2" port, and FA/LB SC-series mounting. Choose the 40 mm adjust window when you need precise on-site extend trimming between 35 and 75 mm. Because this unit has the -S magnet, you must upgrade your sensors from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG. For strokes of 300 mm or longer, verify side-load limits to prevent excessive rod wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X75-40S
- ✓ 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 SUJ100X75-40S FAQ
Yes, the SUJ100X75-40S is discontinued. The direct replacement is the SAUJ100X75-40S, offering the same 100 mm bore, 75 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. You only need to upgrade the -S sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG.
The external stop screw provides a 40 mm adjust window, allowing you to trim the extend stroke from the 75 mm nominal maximum down to 35 mm. The stop sets end position but does not lock the load.
