This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X40-30S, 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 SUJ100X40-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X40-30S is a double-acting profile-type standard cylinder with a Ø100mm bore and 40mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X40-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X40-30S
The AirTAC SUJ100X40-30S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 10-40 mm stroke from the 40 mm nominal maximum. The 1/2" port and M20x1.5 rod end handle high flow, while the 29 mm adjustable cushions decelerate heavy loads. This unit is discontinued; the direct replacement is the SAUJ100X40-30S, retaining the same bore, force, and SC-series FA/LB mounting.
The stop screw sets the extend end position but is not a load lock; use an external rod lock for held loads. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S model. The extruded aluminum profile barrel is more compact than an ISO 15552 cylinder of the same bore, making it ideal when SAUJ beats a fixed SAU plus external stop.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X40-30S 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 SAUJ100X40-30S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SUJ Adjustable Cylinder SUJ100X40-30S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×40 | 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 SUJ100X40-30S Is Used
Short-Stroke Pressing
Trimming the extend stroke by up to 30 mm on-site allows precise 10-40 mm pressing actions without machining custom spacers.
Variable Length Diverter
Field-tuning the extend stop lets a single cylinder adapt the diverter position to changing package sizes on the fly.
Adjustable End Stop
Setting the exact extend endpoint externally simplifies mechanical setup when multiple machines require slightly different stroke ends.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X40-30S with the SAUJ100X40-30S
The -30 adjust window lets you trim the extend stroke by up to 30 mm on-site (usable 10-40 mm) without shims. Because the -S magnet uses legacy CS1-B/DS1-B switches, you must migrate to CMSG/DMSG/EMSG sensors on the SAUJ. For strokes >=300 mm, verify side-load guidance. The stop screw sets end position only; add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X40-30S
- ✓ 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 SUJ100X40-30S FAQ
Yes, the SUJ100X40-30S is discontinued. The direct replacement is the SAUJ100X40-30S, which matches the 100 mm bore, 40 mm stroke, 1/2" port, and force. You must upgrade the -S magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG.
The double-acting double-rod cylinder pushes 3927 N at 0.5 MPa, 5497 N at 0.7 MPa, and 7068 N at 0.9 MPa; pull is 3681 N at 0.5 MPa. The external stop screw window is 30 mm, shortening the 40 mm nominal extend stroke down to 10 mm on-site. The stop sets end position and is not a load lock.
