This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X400-75S, 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 SUJ32X400-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X400-75S is a double-acting profile-type standard cylinder with a Ø32mm bore and 400mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X400-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X400-75S
The AirTAC SUJ32X400-75S 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 325-400 mm extension out of the 400 mm nominal maximum. Featuring a 1/8" port and a 12 mm rod, this compact extruded barrel is shorter than standard cylinders of the same bore.
This SUJ32X400-75S model is discontinued and the direct replacement is the SAUJ32X400-75S, matching the bore, stroke, force, port, and FA/LB mounting. The upgrade path moves from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. 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 SAUJ32X400-75S 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 SAUJ32X400-75S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SUJ Adjustable Cylinder SUJ32X400-75S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×400 | 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 SUJ32X400-75S Is Used
Variable Pitch Indexing
Parts feeding operations needing on-site stroke tuning to alter the push distance by up to 75 mm for different product lengths without swapping cylinders.
Adjustable Transfer Stops
Conveyor diverters where the extend stop position must be dialed in precisely between 325 mm and 400 mm to handle varying package dimensions.
Variable Depth Ejectors
Cartoning machinery requiring field adjustment of the extend stroke to push varying product depths into cases without reprogramming controls.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X400-75S with the SAUJ32X400-75S
To replace the discontinued SUJ32X400-75S, order the direct replacement SAUJ32X400-75S, which preserves the 32 mm bore, 400 mm nominal stroke, 75 mm adjust window, 1/8" port, and FA/LB mounting. The 75 mm adjust window is ideal if your end-stop needs field tuning between 325 mm and 400 mm. Because this -S model has a piston magnet, you must switch from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. At 400 mm stroke, account for side-load and rod-bending by using external guides to prevent premature seal wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X400-75S
- ✓ 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 SUJ32X400-75S FAQ
Yes, the SUJ32X400-75S is discontinued. The direct replacement is the SAUJ32X400-75S, offering the same 32 mm bore, 400 mm stroke, 75 mm adjust window, 1/8" port, and FA/LB mounting. You will need to upgrade your position sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.
The external stop screw allows you to trim the extend stroke by up to 75 mm on-site, giving a usable extension range of 325-400 mm. The stop sets the end position but is not a load lock.
