This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X160-40S, 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 SUJ100X160-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X160-40S is a double-acting profile-type standard cylinder with a Ø100mm bore and 160mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X160-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X160-40S
The AirTAC SUJ100X160-40S 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, giving a usable 120-160 mm range from the 160 mm nominal maximum. It features a 25 mm rod, M20x1.5 rod thread, 29 mm adjustable cushions, and a 1/2" port.
This SUJ model is discontinued and the direct replacement is the SAUJ100X160-40S, retaining the same bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit uses CS1-B/DS1-B switches. The stop screw sets the 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 SAUJ100X160-40S 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 SAUJ100X160-40S 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.
Where the Airtac SUJ Adjustable Cylinder SUJ100X160-40S Is Used
Variable Stroke Pressing
Ideal for light pressing tasks where the extend stroke must be tuned precisely on-site within the 120-160 mm window to accommodate material thickness variations without re-plumbing the machine.
Adjustable Diverter Arms
Used on conveyor lines where a diverter or sorting gate needs field stroke tuning to handle different package sizes, allowing the 40 mm stop screw to set the exact rest position.
Custom End-Stop Positioning
Deployed in material handling fixtures that require a specific extend endpoint to be set mechanically, ensuring repeatable stops for varying pallet dimensions.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X160-40S with the SAUJ100X160-40S
To replace the discontinued SUJ100X160-40S, order the direct replacement SAUJ100X160-40S, which matches the 100 mm bore, 160 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounts. Choose the 40 mm adjust window when you need on-site extend trimming between 120 and 160 mm, which often beats fitting a fixed SAU plus an external stop. Because this unit has the -S magnet, upgrade your legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify your side-load limits to prevent guide wear. The stop screw sets end position only; add an external rod lock for load holding without live air.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X160-40S
- ✓ 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 SUJ100X160-40S FAQ
Yes, the SUJ100X160-40S is discontinued. The direct replacement is the SAUJ100X160-40S, offering the same 100 mm bore, 160 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. You simply need to upgrade the legacy CS1-B/DS1-B sensors to the current CMSG/DMSG/EMSG switches.
The external stop screw provides a 40 mm adjust window, allowing you to shorten the 160 mm nominal extend stroke down to 120 mm on-site. The stop sets end position and is not a load lock.
