This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X40-10, 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 SUJ40X40-10
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X40-10 is a double-acting profile-type standard cylinder with a Ø40mm bore and 40mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X40-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X40-10
The AirTAC SUJ40X40-10 is a double-acting, double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site (usable extend range 30-40 mm). This discontinued unit uses an extruded aluminum barrel that is shorter than an ISO 15552 cylinder of the same bore.
The direct replacement is the SAUJ40X40-10, matching the bore, stroke, force, port, and FA/LB mounting. Note this non-magnet SKU cannot take a switch; the SAUJ uses current CMSG/DMSG/EMSG sensors instead of legacy CS1-B/DS1-B. The stop screw sets end position but is not a load lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X40-10 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 SAUJ40X40-10 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 SUJ40X40-10 Is Used
Diverter Gate Calibration
Trimming the extend stroke by up to 10 mm on-site allows precise positioning of pneumatic diverter gates without machining custom spacers.
Sorting Arm Positioning
Field-tuning the end position lets operators adjust sorting arm travel on the line to accommodate varying package sizes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X40-10 with the SAUJ40X40-10
To replace the discontinued SUJ40X40-10, specify the SAUJ40X40-10 direct, keeping the 40 mm bore, 40 mm nominal stroke, 10 mm adjust window, 1/4" port, and FA/LB mounting. Choose the 10 mm adjust window when you need precise field tuning of the extend end position. Because this is a non-magnet SKU, it cannot take a switch; the SAUJ upgrade uses CMSG/DMSG/EMSG sensors rather than the legacy CS1-B/DS1-B. The stop screw sets end position but is not a lock; for load holding on air loss, specify an external rod lock or pilot-operated check valve. For stroke lengths >=300 mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X40-10
- ✓ 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 SUJ40X40-10 FAQ
Yes, the SUJ40X40-10 is discontinued. The direct replacement is the SAUJ40X40-10, which matches the 40 mm bore, 40 mm stroke, 10 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw window is 10 mm, allowing you to shorten the 40 mm nominal extend stroke down to 30 mm on-site. The stop sets end position but is not a load lock.
