This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X450-100, 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 SUJ100X450-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X450-100 is a double-acting profile-type standard cylinder with a Ø100mm bore and 450mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X450-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X450-100
The AirTAC SUJ100X450-100 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 extension from the 450 mm nominal maximum. The 1/2" port and extruded aluminum barrel make it shorter than a standard ISO cylinder of the same bore.
This SUJ model is discontinued; the direct replacement is the SAUJ100X450-100, matching the bore, stroke, 801 kgf max force, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors since this legacy unit used CS1-B/DS1-B switches. Note that the stop screw sets end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X450-100 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUJ100X450-100 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 SUJ100X450-100 Is Used
Variable Length Ejection
Tuning the extend stroke by up to 100 mm on-site allows an ejection arm to adapt to varying product lengths without swapping the entire cylinder.
Adjustable Diverter Gate
Trimming the stroke precisely positions a diverter gate to route different package sizes on a single conveyor line.
Custom Format Stops
Field-adjusting the end position provides flexible physical stops for palletizing operations where layer heights change frequently.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X450-100 with the SAUJ100X450-100
To replace the discontinued SUJ100X450-100, order the direct replacement SAUJ100X450-100, which preserves the 100 mm bore, 450 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 100 mm adjust window when you need to trim the extend stroke on-site by up to 100 mm; if you require less variability, a smaller adjust screw suffices. Because this SKU lacks a magnet, it cannot take a sensor; if you need position detection, select an -S SAUJ and use CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For the 450 mm stroke, use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X450-100
- ✓ 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 SUJ100X450-100 FAQ
Yes, the SUJ100X450-100 is discontinued. The direct replacement is the SAUJ100X450-100, which matches the 100 mm bore, 450 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw window is 100 mm, allowing you to shorten the extend stroke from the 450 mm maximum down to 350 mm on-site. The stop sets end position but is not a load lock.
