This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ63X450-100S, 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 SUJ63X450-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X450-100S 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 SAUJ63X450-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X450-100S
The AirTAC SUJ63X450-100S 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. This SUJ unit is discontinued; the direct replacement is the SAUJ63X450-100S, retaining the same force, port, and FA/LB mounting.
The stop screw sets end position only—it is not a load lock, so use an external rod lock for held loads. The SAUJ upgrade switches sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG. At 450 mm stroke, use external guides to prevent rod bending.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X450-100S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAUJ63X450-100S 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 SUJ63X450-100S Is Used
Variable Pitch Push Stations
Adjusting the extend stroke on-site by up to 100 mm allows a single 450 mm cylinder to drive parts pushers for multiple product lengths without changing the actuator body.
Adjustable Diverter Arms
Trimming the extend end position lets operators fine-tune diverter stroke length on the fly to accommodate varying package widths on a packaging line.
Tunable Stacking Rams
The 100 mm external stop window provides the flexibility to set precise stacking heights for different pallet loads while using the full 450 mm stroke as a maximum.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X450-100S with the SAUJ63X450-100S
To replace the discontinued SUJ63X450-100S, order the direct replacement SAUJ63X450-100S, which matches the 63 mm bore, 450 mm max stroke, 100 mm adjust window, 3/8" port, and FA/LB mounting. Choose the -100S adjust window if you need to tune the extend stroke on-site by up to 100 mm. Because this unit has a magnet (-S), swap legacy CS1-B/DS1-B switches for CMSG/DMSG/EMSG sensors on the SAUJ. At 450 mm stroke, add external guides to manage side-load and rod-bending forces.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X450-100S
- ✓ 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 SUJ63X450-100S FAQ
Yes, the SUJ63X450-100S is discontinued. The direct replacement is the SAUJ63X450-100S, which matches the 63 mm bore, 450 mm stroke, 100 mm adjust window, 3/8" port, and FA/LB mounting. You must upgrade the position sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.
The external stop screw allows you to trim the extend stroke by up to 100 mm on-site, giving a usable extend range of 350-450 mm. The stop sets end position only and is not a load lock.
