This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X125-40S, 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 SUJ32X125-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X125-40S is a double-acting profile-type standard cylinder with a Ø32mm bore and 125mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X125-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X125-40S
The AirTAC SUJ32X125-40S is a double-acting double-rod profile cylinder with a 125 mm nominal stroke and an external stop screw that lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 85-125 mm window. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.
The direct replacement is the SAUJ32X125-40S, which matches the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of this model's legacy CS1-B/DS1-B switches, while retaining the compact profile barrel.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X125-40S 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 SAUJ32X125-40S 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). |
|---|---|
| 32 | Bore size in mm. |
| ×125 | 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 SUJ32X125-40S Is Used
Variable Pitch Sorting
Tuning the extend stroke on-site by up to 40 mm allows a single 32 mm bore cylinder to adapt to changing product pitches without swapping out the entire actuator.
Adjustable Diverter Gate
The 85-125 mm usable stroke window lets operators fine-tune the gate extension length precisely to the conveyor lane width required for each run.
Carton Flap Folding
Field-trimming the extend stroke prevents over-travel when folding varying carton sizes, using the external stop screw to set the exact end position.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X125-40S with the SAUJ32X125-40S
To replace the discontinued SUJ32X125-40S, order the direct replacement SAUJ32X125-40S, which preserves the 32 mm bore, 125 mm stroke, 1/8" port, and FA/LB mounting. Choose the 40 mm adjust window if your fixture needs field tuning between 85 mm and 125 mm. Retain the -S magnet option, but note the SAUJ requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X125-40S
- ✓ 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 SUJ32X125-40S FAQ
Yes, the SUJ32X125-40S is discontinued. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw offers a 40 mm adjust window, allowing you to shorten the 125 mm nominal extend stroke down to 85 mm on-site.
