This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X125-75S, 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 SUJ32X125-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X125-75S 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 SAUJ32X125-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X125-75S
The AirTAC SUJ32X125-75S 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 50-125 mm extension from the 125 mm nominal maximum. The compact extruded aluminum barrel is notably shorter than a standard cylinder of the same 32 mm bore. This specific model is DISCONTINUED; the direct replacement is the SAUJ32X125-75S, retaining the 1/8" port, M10x1.25 rod thread, and 21 mm adjustable cushions. The stop screw sets the end position but is not a load lock.
Because it includes a piston magnet (-S), it supports position sensing. Note that the legacy CS1-B/DS1-B switches used here are superseded by CMSG/DMSG/EMSG sensors on the SAUJ replacement. A plain cylinder drifts on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X125-75S 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 SAUJ32X125-75S 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 SUJ32X125-75S Is Used
Variable Pitch Push Stations
Dialing in the extend stroke by up to 75 mm on-site allows a single 32 mm bore cylinder to push parts of varying widths into a press without swapping mechanical spacers.
Adjustable Transfer Diverters
Field-trimming the rod extension lets operators reposition sorting gates along the belt to accommodate different package sizes on the fly.
Customizable End-Stops
The external stop screw provides a hard, adjustable mechanical end position for pallet lifting probes, enabling precise depth setting without reprogramming the PLC.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X125-75S with the SAUJ32X125-75S
To replace the discontinued SUJ32X125-75S, order the SAUJ32X125-75S; it is a direct swap maintaining the 32 mm bore, 125 mm stroke, 75 mm adjust window, 1/8" port, and FA/LB mounting compatibility with the AirTAC SC series. Select the 75 mm adjust window if your mechanism requires field-tuning the extend stroke down to a 50 mm minimum. For the -S magnet version, upgrade your sensing to the current CMSG/DMSG/EMSG series, as the legacy CS1-B/DS1-B switches are obsolete. For strokes of 300 mm or longer, verify side-load constraints to prevent rod binding. The external stop screw defines end position only; it does not lock the load, so add a pilot-operated check valve or external rod lock if the application requires load holding on air loss.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X125-75S
- ✓ 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 SUJ32X125-75S FAQ
Yes, the AirTAC SUJ32X125-75S is discontinued. The direct replacement is the SAUJ32X125-75S, which shares the same 32 mm bore, 125 mm nominal stroke, 75 mm adjust window, 1/8" port, and FA/LB mounting. You must upgrade your position sensors from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG series.
The external stop screw provides a 75 mm adjustment window, allowing you to shorten the 125 mm maximum extend stroke down to 50 mm on-site. The stop sets end position only and is not a load lock.
