This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X225-20S, 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 SUJ32X225-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X225-20S is a double-acting profile-type standard cylinder with a Ø32mm bore and 225mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X225-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X225-20S
The AirTAC SUJ32X225-20S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 205-225 mm extension out of the 225 mm nominal maximum.
This unit is discontinued; the direct replacement is the SAUJ32X225-20S, retaining the same bore, stroke, force, and SC-series FA/LB mounting. The upgrade path moves magnet sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. Note that the stop screw sets the end position but is not a load lock; an external rod lock is required to hold loads on air loss.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X225-20S 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 SAUJ32X225-20S 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 SUJ32X225-20S Is Used
Diverter Gate Positioning
Allows maintenance crews to dial in the exact 205-225 mm extend position of a sorting diverter on-site without machining custom spacers.
Variable-Length Product Stops
Provides an adjustable mechanical end-stop for different package lengths on a packing line, trimming the extend stroke by up to 20 mm as needed.
Calibrated Ejector Pins
Enables operators to fine-tune the ejection stroke of lightweight parts within the 20 mm window to accommodate varying mold depths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X225-20S with the SAUJ32X225-20S
To replace the discontinued SUJ32X225-20S, order the direct replacement SAUJ32X225-20S, which matches the 32 mm bore, 225 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 20 mm adjust window if your application requires precise field tuning of the extend stroke within the 205-225 mm range. Because this model includes the -S magnet, you must upgrade your sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load constraints to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X225-20S
- ✓ 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 SUJ32X225-20S FAQ
Yes, the SUJ32X225-20S is discontinued. The direct replacement is the SAUJ32X225-20S, which shares the same 32 mm bore, 225 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. You will need to upgrade your position sensing from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors.
The external stop screw provides a 20 mm adjust window, allowing you to shorten the 225 mm nominal extend stroke down to 205 mm on-site. The stop sets end position but is not a load lock.
