This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X75-75S, 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 SUJ32X75-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X75-75S is a double-acting profile-type standard cylinder with a Ø32mm bore and 75mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X75-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X75-75S
The AirTAC SUJ32X75-75S is a double-acting double-rod profile cylinder with a 75 mm adjustable stroke window, letting you trim the extend stroke by up to 75 mm on-site via an external stop screw. 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 SAUJ32X75-75S, retaining the same force, porting, and FA/LB mounting. The SAUJ upgrade switches legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches and offers a shorter profile barrel than ISO 15552 equivalents.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X75-75S 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 SAUJ32X75-75S 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 SUJ32X75-75S Is Used
Variable Pitch Pushing
Trimming the extend stroke on-site to push parts of varying lengths into a machining center without repositioning the cylinder body.
Adjustable Forming Stops
Setting precise end-of-stroke positions for pressing or forming operations where the material thickness requires frequent field adjustments.
Dynamic Sorting Diverter
Altering the diverter stroke length on a packaging line to handle different box sizes on the fly without swapping out the actuator.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X75-75S with the SAUJ32X75-75S
To replace the discontinued SUJ32X75-75S, order the direct replacement SAUJ32X75-75S, keeping the 75 mm adjust window and 1/8" port. The -S suffix means your legacy CS1-B/DS1-B sensors must change to CMSG/DMSG/EMSG switches on the SAUJ. FA and LB mounts are supported. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. Remember the stop screw sets end position and does not hold loads without live air.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X75-75S
- ✓ 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 SUJ32X75-75S FAQ
Yes, the SUJ32X75-75S is discontinued. The direct replacement is the SAUJ32X75-75S, which matches the 32 mm bore, 75 mm stroke, 75 mm adjust window, 1/8" port, and FA/LB mounting. You must upgrade your legacy CS1-B/DS1-B sensors to the current CMSG/DMSG/EMSG switches.
The external stop screw allows you to shorten the extend stroke by up to 75 mm on-site. The stop sets end position only; it is not a load lock.
