This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X250-30S, 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 SUJ32X250-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X250-30S is a double-acting profile-type standard cylinder with a Ø32mm bore and 250mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X250-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X250-30S
The AirTAC SUJ32X250-30S is a discontinued double-acting double-rod profile cylinder with a 32 mm bore and 1/8" port. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable 220-250 mm end position. The stop sets the end position but is not a load lock; use an external rod lock for held loads.
The direct replacement is the SAUJ32X250-30S, sharing the same compact profile body, force, and FA/LB mounting. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S model.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X250-30S 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 SAUJ32X250-30S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 32 | Bore size in mm. |
| ×250 | 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 SUJ32X250-30S Is Used
Variable Pitch Pushing
Tuning the extend stroke on-site by up to 30 mm to push parts of varying widths into a machining station without swapping the cylinder.
Adjustable Diverter Gate
Setting a precise 220-250 mm extend position to deflect different package sizes on a conveyor line, allowing rapid field changes.
Custom Depth Stops
Calibrating the extend end position for stacking or positioning tasks where the target depth varies slightly between product runs.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X250-30S with the SAUJ32X250-30S
To replace the SUJ32X250-30S, order the direct replacement SAUJ32X250-30S, which retains the 32 mm bore, 250 mm max stroke, 30 mm adjust window, and 1/8" port. Choose the 30 mm adjust window if you need on-site extend tuning between 220-250 mm; the stop screw sets end position but is not a lock. Mounting uses basic, FA, or LB brackets (SC-series compatible). Because this -S model has a magnet, you must migrate from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For this 250 mm stroke, confirm side-load limits on the rod end.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X250-30S
- ✓ 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 SUJ32X250-30S FAQ
Yes, the SUJ32X250-30S is discontinued. The direct replacement is the SAUJ32X250-30S, which matches the 32 mm bore, 250 mm stroke, 30 mm adjust window, and 1/8" port. You will need to upgrade the position sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.
This double-acting double-rod cylinder has a 30 mm adjust window, allowing you to shorten the 250 mm extend stroke down to 220 mm on-site. The external stop sets the end position but is not a load lock.
