This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ63X225-100, 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 SUJ63X225-100
The AirTAC SUJ Adjustable Cylinder SUJ63X225-100 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 SAUJ63X225-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X225-100
The AirTAC SUJ63X225-100 is a discontinued double-acting double-rod profile cylinder with a 225 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 125-225 mm window. This compact extruded-aluminum body is notably shorter than a standard ISO 15552 cylinder of the same bore. The bore dictates a 3/8" port and a 20 mm rod with an M16x1.5 thread.
Because the SUJ series is end-of-life, the direct replacement is the SAUJ63X225-100, matching the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here. Note this non-magnet SKU cannot accept a sensor. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X225-100 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 SAUJ63X225-100 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 SUJ63X225-100 Is Used
Variable Stroke Clamping
Adjusts the extend stop on-site to clamp parts of differing heights without reprogramming the PLC or moving the cylinder mount.
Adjustable Transfer Pusher
Trims the extend stroke by up to 100 mm to push varying box sizes onto a secondary belt, tuning the end position mechanically.
Format Change Diverter
Provides a 125-225 mm extend window to accommodate packaging format changes on the fly, setting the exact reject distance via the stop screw.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X225-100 with the SAUJ63X225-100
To replace the discontinued SUJ63X225-100, order the direct replacement SAUJ63X225-100, which preserves the 63 mm bore, 225 mm 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. This non-magnet version cannot take a switch, but if you select a -S SAUJ, plan for the current CMSG/DMSG/EMSG sensors rather than the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X225-100
- ✓ 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 SUJ63X225-100 FAQ
Yes, the SUJ63X225-100 is discontinued. The direct replacement is the SAUJ63X225-100, which matches the 63 mm bore, 225 mm stroke, 100 mm adjust window, 3/8" 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 provides a 100 mm adjust window, allowing the 225 mm extend stroke to be shortened to 125 mm on-site. The stop sets end position but is not a load lock.
