This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X450-20, 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 SUJ32X450-20
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X450-20 is a double-acting profile-type standard cylinder with a Ø32mm bore and 450mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X450-20, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X450-20
The AirTAC SUJ32X450-20 is a double-acting double-rod profile cylinder with a 450 mm nominal stroke and a 20 mm adjustable stroke window. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 430-450 mm end position. The stop screw sets the end position but is not a load lock; loads drift on air loss.
This SUJ32X450-20 model is discontinued and the direct replacement is the SAUJ32X450-20, retaining the same bore, stroke, force, port, and SC-series FA/LB mounting. The SAUJ upgrades sensing to current CMSG/DMSG/EMSG switches, whereas this legacy unit used CS1-B/DS1-B sensors. Note this specific SKU lacks a magnet and cannot take a switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X450-20 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 SAUJ32X450-20 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 SUJ32X450-20 Is Used
Diverter Gate Positioning
Trimming the extend stroke by up to 20 mm on-site allows exact alignment of diverter gates without machining spacer plates.
Package Stopper Tuning
Adjustable end positioning lets operators fine-tune the stopping point for varying carton sizes on a 32 mm bore actuator.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X450-20 with the SAUJ32X450-20
To replace the discontinued SUJ32X450-20, order the direct replacement SAUJ32X450-20, which matches the 32 mm bore, 450 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 20 mm adjust window if you need on-site extend trimming from 450 mm down to 430 mm. Because this SKU has no magnet, it cannot accept sensors; the SAUJ requires CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. At 450 mm stroke, prevent rod bending by using external guides to manage side loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X450-20
- ✓ 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 SUJ32X450-20 FAQ
Yes, the SUJ32X450-20 is discontinued. The direct replacement is the SAUJ32X450-20, offering the same 32 mm bore, 450 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting.
The external stop screw window is 20 mm, allowing you to shorten the 450 mm extend stroke down to 430 mm.
