This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X175-40S, 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 SUJ32X175-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X175-40S is a double-acting profile-type standard cylinder with a Ø32mm bore and 175mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X175-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X175-40S
The AirTAC SUJ32X175-40S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 135-175 mm window from the 175 mm nominal maximum. This compact extruded-aluminum barrel is shorter than a standard cylinder of the same bore.
This SUJ32X175-40S is discontinued; the direct replacement is the SAUJ32X175-40S, retaining the same bore, stroke, force, port, and SC-series FA/LB mounting. The legacy CS1-B/DS1-B sensors on this -S magnet model are superseded by current CMSG/DMSG/EMSG switches on the SAUJ. Note 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 SAUJ32X175-40S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUJ32X175-40S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | 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 SUJ32X175-40S Is Used
Variable Depth Boring
Adjusts the extend stroke on-site to machine varying pocket depths without swapping the entire actuator.
Variable Length Sorting Diverter
Trims the extend stroke by up to 40 mm to deflect different package sizes accurately on a moving belt.
Adjustable Height Stopper
Fine-tunes the end position to act as a physical stop for varying pallet heights in a packing zone.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X175-40S with the SAUJ32X175-40S
To replace the discontinued SUJ32X175-40S, order the direct replacement SAUJ32X175-40S, which matches the 32 mm bore, 175 mm stroke, 40 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 40 mm adjust window if you need to tune the extend stroke down to 135 mm on-site; this often beats installing a fixed-stroke SAU plus an external stop. Because this is a -S model, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches. For this 175 mm stroke, verify side-load limits, and remember the stop screw sets end position but is not a load lock.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X175-40S
- ✓ 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 SUJ32X175-40S FAQ
Yes, the SUJ32X175-40S is discontinued. The direct replacement is the SAUJ32X175-40S, which matches the 32 mm bore, 175 mm stroke, 40 mm adjust window, 1/8" port, and FA/LB mounting. You only need to upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The external stop screw window is 40 mm, allowing you to shorten the 175 mm nominal extend stroke down to 135 mm. The stop sets end position only; it is not a load lock.
