This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X175-10S, 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 SUJ40X175-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X175-10S is a double-acting profile-type standard cylinder with a Ø40mm bore and 175mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X175-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X175-10S
The AirTAC SUJ40X175-10S 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, yielding a usable 165-175 mm stroke. The nominal 175 mm is the maximum. This discontinued model is fully replaced by the SAUJ40X175-10S.
The direct replacement SAUJ40X175-10S keeps the exact bore, stroke, force, port, and FA/LB mounting. Upgrading brings current CMSG/DMSG/EMSG sensors to replace the SUJ's legacy CS1-B/DS1-B switches. The stop screw sets 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 SAUJ40X175-10S 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 SAUJ40X175-10S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 40 | Bore size in mm. |
| ×175 | 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 SUJ40X175-10S Is Used
Diverter Gate Positioning
Trimming the extend stroke by up to 10 mm on-site allows precise alignment of diverter gates on packaging lines without disassembling the cylinder or machining spacers.
Product Stopper Height Tuning
When product sizes vary slightly, the external stop screw lets operators dial in the exact 165-175 mm extend position to act as an adjustable physical stop on the conveyor belt.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X175-10S with the SAUJ40X175-10S
To replace the SUJ40X175-10S, order the direct replacement SAUJ40X175-10S, which preserves the 40 mm bore, 175 mm stroke, 10 mm adjust window, 1/4" port, and FA/LB mounting. Because this unit has the -S magnet, you must swap the legacy CS1-B/DS1-B switches for current CMSG/DMSG/EMSG sensors. The 10 mm adjust window is ideal when you need precise field tuning of the extend end-position without machining a custom fixed stroke. For this 175 mm stroke, verify side-load alignment to prevent rod binding. Remember the stop screw only sets the end position and does not hold the load on air loss; install an external rod lock for suspended loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X175-10S
- ✓ 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 SUJ40X175-10S FAQ
Yes, the AirTAC SUJ40X175-10S is discontinued. The direct replacement is the SAUJ40X175-10S, which matches the 40 mm bore, 175 mm stroke, 10 mm adjust window, 1/4" port, and FA/LB mounting. You will need to upgrade the -S magnet switches from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG sensors.
The theoretical maximum force is 128 kgf at 1.0 MPa. The external stop screw provides a 10 mm adjust window, meaning you can shorten the 175 mm maximum extend stroke down to 165 mm on-site. The stop sets end position but is not a load lock.
