This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X80-10S, 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 SUJ40X80-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X80-10S is a double-acting profile-type standard cylinder with a Ø40mm bore and 80mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X80-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X80-10S
The AirTAC SUJ40X80-10S 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 10 mm, giving a usable 70-80 mm range from the 80 mm nominal maximum. This discontinued unit is fully replaced by the SAUJ40X80-10S.
The direct replacement SAUJ40X80-10S retains the exact bore, stroke, force, and SC-series FA/LB mounting, but upgrades sensing to current CMSG/DMSG/EMSG switches from the legacy CS1-B/DS1-B used here. The stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X80-10S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAUJ40X80-10S 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 SUJ40X80-10S Is Used
Probe Contact Tuning
Trimming the extend stroke by up to 10 mm on-site allows precise depth setting for testing probes without machining custom spacers.
Diverter Gate Adjustment
Field-tuning the extend end position accommodates varying package sizes on a conveyor line, ensuring the gate deflects accurately.
Clamp Positioning
Setting the exact 70-80 mm extend stop on-site ensures delicate parts are clamped securely without overtravel, adapting to fixture variations.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X80-10S with the SAUJ40X80-10S
To replace this discontinued SUJ40X80-10S, specify the SAUJ40X80-10S for an direct swap retaining the 1/4" port and 10 mm adjust window. Choose the 10 mm adjust window if you need precise end-position tuning without adding an external stop. Mounting uses FA or LB brackets. Because this unit has the -S magnet, upgrade your position sensing from CS1-B/DS1-B to CMSG/DMSG/EMSG. For stroke lengths of 300 mm or greater, verify side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X80-10S
- ✓ 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 SUJ40X80-10S FAQ
Yes, the SUJ40X80-10S is discontinued. The direct replacement is the SAUJ40X80-10S, which matches the 40 mm bore, 80 mm stroke, 10 mm adjust window, 1/4" port, and FA/LB mounting. You must upgrade the position sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The external stop screw offers a 10 mm adjust window, allowing you to shorten the extend stroke from the 80 mm maximum down to 70 mm. The stop sets end position only and does not hold the load on air loss.
