This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X450-100S, 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 SUJ32X450-100S
The AirTAC SUJ Adjustable Cylinder SUJ32X450-100S 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 SAUJ32X450-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X450-100S
The AirTAC SUJ32X450-100S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 350-450 mm stroke from the 450 mm nominal maximum. 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 SAUJ32X450-100S, matching the bore, stroke, force, port, 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 magnet model.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X450-100S 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 SAUJ32X450-100S 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 SUJ32X450-100S Is Used
Variable Push Fixtures
Trimming the extend stroke by up to 100 mm on-site allows precise positioning of clamping faces on parts with varying widths without re-plumbing the 1/8" port.
Adjustable Diverters
Tuning the extend end position lets a single 32 mm bore cylinder accommodate different package sizes on a line, setting the divert stroke between 350 and 450 mm.
Variable Depth Stops
Field-adjusting the extend stroke provides flexible end-stop depths for shelving or sorting operations where the required reach changes between production runs.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X450-100S with the SAUJ32X450-100S
To replace the discontinued SUJ32X450-100S, order the SAUJ32X450-100S for an direct match in bore, 450 mm stroke, 100 mm adjust window, and 1/8" port. Choose the 100 mm adjust window if you need on-site extend trimming from 350 to 450 mm. The SAUJ accepts FA and LB mounts, and its -S variant uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. Because the stroke is 450 mm, ensure external guides support side-load to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X450-100S
- ✓ 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 SUJ32X450-100S FAQ
Yes, the SUJ32X450-100S is discontinued. The direct replacement is the SAUJ32X450-100S, which matches the 32 mm bore, 450 mm stroke, 100 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw window is 100 mm, allowing you to shorten the 450 mm nominal extend stroke down to 350 mm on-site. The stop sets end position and is not a load lock.
