This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X450-75, 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 SUJ100X450-75
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X450-75 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 SAUJ100X450-75, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X450-75
The AirTAC SUJ100X450-75 is a double-acting double-rod adjustable-stroke profile cylinder, now discontinued and replaced by the direct replacement SAUJ100X450-75. It features a 100mm bore, 1/2 inch port, and an external stop screw that lets you trim the extend stroke by up to 75mm on-site, giving a usable 375-450mm stroke. The profile barrel is shorter than an ISO 15552 cylinder of the same bore.
The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. The SAUJ upgrade retains the FA/LB mounting but moves to current CMSG/DMSG/EMSG sensors (this legacy SKU used CS1-B/DS1-B). This non-magnet SKU cannot take a switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X450-75 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 SAUJ100X450-75 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 SUJ100X450-75 Is Used
Variable-Length Ejector
Tuning the extend stroke by up to 75mm on-site allows a 100mm bore ejector to adapt to varying product depths without swapping cylinders.
Adjustable Diverter Gate
Trimming the 450mm stroke lets a diverter gate accommodate different package widths on the fly, ensuring precise routing without mechanical spacers.
Variable-Stop Pusher
An external stop screw provides a hard, repeatable end position for pushing heavy pallets, adjustable from 375mm to 450mm as layout needs evolve.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X450-75 with the SAUJ100X450-75
To replace the discontinued SUJ100X450-75, order the exact direct replacement SAUJ100X450-75, which preserves the 100mm bore, 450mm nominal stroke, 75mm adjust window, 1/2 inch port, and FA/LB mounting. Choose the 75mm adjust window when you need to trim the extend stroke by up to 75mm on-site. Because this SKU lacks a magnet, it cannot take a sensor; the SAUJ replacement uses current CMSG/DMSG/EMSG sensors (the SUJ used legacy CS1-B/DS1-B). For the 450mm stroke, use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X450-75
- ✓ 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 SUJ100X450-75 FAQ
Yes, the SUJ100X450-75 is discontinued. The direct replacement is the SAUJ100X450-75, which matches the 100mm bore, 450mm stroke, 75mm adjust window, 1/2 inch port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw trims the extend stroke by up to 75mm on-site (usable 375-450mm). The stop sets end position but is not a load lock; use an external rod lock for held loads.
