This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ63X225-100S, 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 SUJ63X225-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X225-100S is a double-acting profile-type standard cylinder with a Ø63mm bore and 225mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ63X225-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X225-100S
The AirTAC SUJ63X225-100S 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 125-225 mm extension from the 225 mm nominal maximum. It features a 3/8" port, a Ø20 mm piston rod with an M16x1.5 thread, and 21 mm adjustable air cushions at each end. This SUJ model is discontinued; the direct replacement is the SAUJ63X225-100S, which retains the same bore, stroke, force, port, and FA/LB mounting.
The SAUJ successor upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit uses CS1-B/DS1-B switches (indicated by the -S suffix). The external stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock for held loads. The compact extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X225-100S 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 SAUJ63X225-100S 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 SUJ63X225-100S Is Used
Variable Stroke Clamping
Adjusts the extend stroke on-site to clamp parts of varying heights without swapping the entire cylinder.
Adjustable Transfer Stops
Trims the extend position to act as a physical stop for different product lengths on a packaging line.
Tunable Ejector Pushers
Dials in the exact ejection distance for mixed-size cartons, preventing over-travel damage.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X225-100S with the SAUJ63X225-100S
To replace the discontinued SUJ63X225-100S, order the direct replacement SAUJ63X225-100S, which matches the 63 mm bore, 225 mm nominal stroke, 100 mm adjust window, 3/8" port, and FA/LB mounting. Choose the 100 mm adjust window if you need to trim the extend stroke down to a 125 mm minimum on-site. Because this unit has the -S magnet, you must upgrade your legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors on the SAUJ. For this 225 mm stroke, ensure your mechanical setup handles side-load thrust within the SC-series mounting constraints. The stop screw sets end position only; it is not a lock, so add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X225-100S
- ✓ 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 SUJ63X225-100S FAQ
Yes, the SUJ63X225-100S is discontinued. The direct replacement is the SAUJ63X225-100S, which matches the 63 mm bore, 225 mm stroke, 100 mm adjust window, 3/8" port, and FA/LB mounting. You will need to upgrade the legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG switches.
The external stop screw window is 100 mm, allowing you to trim the 225 mm nominal extend stroke down to 125 mm on-site. The stop sets end position but is not a load lock.
