This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ63X450-10, 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 SUJ63X450-10
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X450-10 is a double-acting profile-type standard cylinder with a Ø63mm bore and 450mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ63X450-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X450-10
The AirTAC SUJ63X450-10 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 440-450 mm stroke. It features a 3/8" port, a 20 mm rod, and 21 mm adjustable cushions. The direct replacement is the SAUJ63X450-10, matching the bore, stroke, force, and mounting.
The SAUJ upgrade switches legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. The stop screw sets the end position but is not a load lock; use an external rod lock to hold loads. At 450 mm, external guides are advised to prevent rod bending.

|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAUJ63X450-10 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 SUJ63X450-10 Is Used
Assembly Press Tuning
Dialing in a 445 mm press stroke on-site to seat a delicate bearing without bottoming out the full 450 mm travel.
Variable Length Diverter
Adjusting a diverter arm's extend position by up to 10 mm to accommodate slightly different carton depths on the line.
Packaging Stop Positioning
Fine-tuning the end-of-stroke stop on a 450 mm actuator to perfectly align film wrapping edges before sealing.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X450-10 with the SAUJ63X450-10
To replace the discontinued SUJ63X450-10, order the direct replacement SAUJ63X450-10. If migrating sensors, note that legacy CS1-B/DS1-B switches are replaced by current CMSG/DMSG/EMSG series on the SAUJ. The 10 mm adjust window allows precise 440-450 mm extend tuning without needing a custom cylinder. Mounting uses AirTAC SC series FA or LB brackets. Because the 450 mm stroke is long, use external guides to prevent rod bending and manage side loads. This non-magnetic SKU cannot take a switch.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X450-10
- ✓ 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 SUJ63X450-10 FAQ
Yes, the SUJ63X450-10 is discontinued. The direct replacement is the SAUJ63X450-10, which matches the 63 mm bore, 450 mm stroke, 3/8" port, and force. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw window is 10 mm, allowing you to trim the extend stroke from the 450 mm maximum down to 440 mm. The stop sets position but is not a load lock.
