This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X450-100S, 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 SUJ100X450-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X450-100S 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 SAUJ100X450-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X450-100S
The AirTAC SUJ100X450-100S is a discontinued 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 window from the 450 mm nominal maximum. It features a 1/2" port, a 25 mm rod, and 29 mm adjustable cushions. This SUJ model is discontinued; the direct replacement is the SAUJ100X450-100S, retaining the same bore, stroke, force, port, and FA/LB mounting.
Two distinct advantages of this lineage are the compact extruded aluminum profile barrel—shorter than an ISO 15552 cylinder of the same bore—and the on-site adjustability, which often beats fitting a fixed-stroke cylinder with a custom external stop. Note the -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches; the SAUJ replacement upgrades to current CMSG/DMSG/EMSG sensors. The stop screw sets the end position but is not a load lock; without live air the piston drifts, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X450-100S 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 SAUJ100X450-100S 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 SUJ100X450-100S Is Used
Variable-Length Pressing
Allows operators to fine-tune the extend stop on-site for pressing assemblies to varying depths without swapping the entire cylinder.
Adjustable Transfer Diverter
Provides field-adjustable extension to deflect different package sizes on a conveyor line, trimming the stroke up to 100 mm as needed.
Modular Shelf Loading
Accommodates changing rack heights by dialing in the extend end position, ensuring precise placement without re-engineering the pneumatic setup.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X450-100S with the SAUJ100X450-100S
To replace the discontinued SUJ100X450-100S, order the direct replacement SAUJ100X450-100S, which preserves the 100 mm bore, 450 mm nominal stroke, 100 mm adjust window, 1/2" port, and FA/LB/Basic mounting. Choose the 100 mm adjust window if your end-position tuning requires the full 350-450 mm range. For the -S magnet, swap legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAUJ. Because the 450 mm stroke exceeds 300 mm, account for rod-bending and side-load forces by incorporating external guides to prevent premature seal wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X450-100S
- ✓ 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 SUJ100X450-100S FAQ
Yes, the SUJ100X450-100S is discontinued. The direct replacement is the SAUJ100X450-100S, matching the 100 mm bore, 450 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also supports the SAUF built-in-valve variant and uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw provides a 100 mm adjust window, shortening the extend stroke from the 450 mm maximum down to 350 mm. The stop sets end position but is not a load lock.
