This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X150-75S, 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 SUJ40X150-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X150-75S is a double-acting profile-type standard cylinder with a Ø40mm bore and 150mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X150-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X150-75S
The AirTAC SUJ40X150-75S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 75-150 mm extend window from the 150 mm nominal maximum. This discontinued unit used a CS1-B/DS1-B magnet for position sensing; the direct replacement SAUJ40X150-75S retains the exact bore, stroke, force, and FA/LB mounting but upgrades to current CMSG/DMSG/EMSG sensors.
The external stop sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock for held loads. The compact profile barrel is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X150-75S 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 SAUJ40X150-75S 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 SUJ40X150-75S Is Used
Variable Depth Drilling
Trimming the extend stroke by up to 75 mm on-site allows precise depth control for drilling or tapping operations without swapping cylinders.
Adjustable Diverter Arms
Field-tuning the extend window from 75 to 150 mm accommodates changing package sizes on a conveyor line without mechanical rework.
Variable Stop Positioning
Setting a custom end position via the external stop screw provides flexible part push-off distances at packing stations.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X150-75S with the SAUJ40X150-75S
To replace the discontinued SUJ40X150-75S, specify the direct replacement SAUJ40X150-75S, which matches the 40 mm bore, 150 mm nominal stroke, 75 mm adjust window, 1/4" port, and FA/LB mounting. Choose the 75 mm adjust window when you need field-tuning of the extend stroke within the 75-150 mm range. Because this unit has the -S magnet, note the sensor change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG on the SAUJ. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X150-75S
- ✓ 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 SUJ40X150-75S FAQ
Yes, the SUJ40X150-75S is discontinued. The direct replacement is the SAUJ40X150-75S, which shares the same 40 mm bore, 150 mm stroke, 75 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ upgrades the position sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The external stop screw provides a 75 mm adjust window, allowing you to shorten the 150 mm nominal extend stroke down to 75 mm on-site. The stop sets end position but is not a load lock.
