This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X225-20S, 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 SUJ100X225-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X225-20S is a double-acting profile-type standard cylinder with a Ø100mm bore and 225mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X225-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X225-20S
The AirTAC SUJ100X225-20S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, giving a usable 205-225 mm forward travel out of the 225 mm nominal maximum. The 1/2" port and M20x1.5 rod end handle high flow, while the 29 mm adjustable cushions decelerate heavy loads. This discontinued unit used a CS1-B/DS1-B magnet; the direct replacement SAUJ100X225-20S retains the exact bore, stroke, force, and FA/LB mounting.
The stop screw sets the end position but is not a lock; loads drift on air loss, so add an external rod lock for holding. The SAUJ replacement upgrades sensing to current CMSG/DMSG/EMSG switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X225-20S 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 SAUJ100X225-20S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ100X225-20S Is Used
Press Fit Tuning
Dialing in the exact 205-225 mm extend position for a press fit operation without machining custom spacers.
Variable Length Diverter
Adjusting a diverter arm's reach on-site to accommodate different package sizes on a packaging line.
Pallet Stop Positioning
Fine-tuning the forward stop point for varying pallet dimensions while maintaining high push force.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X225-20S with the SAUJ100X225-20S
To replace the discontinued SUJ100X225-20S, order the direct replacement SAUJ100X225-20S, which preserves the 100 mm bore, 225 mm stroke, 20 mm adjust window, 1/2" port, and FA/LB mounting. Select the -20 mm adjust window if your mechanism requires precise 205-225 mm extend tuning without shimming. Because this unit has the -S magnet, you must migrate from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors on the SAUJ. For this 225 mm stroke, verify side-load alignment as standard practice. The external stop sets end position only; specify an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X225-20S
- ✓ 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 SUJ100X225-20S FAQ
Yes, the SUJ100X225-20S is discontinued. The direct replacement is the SAUJ100X225-20S, which matches the 100 mm bore, 225 mm stroke, 20 mm adjust window, 1/2" port, and FA/LB mounting. You must upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The external stop screw offers a 20 mm adjust window, allowing you to trim the 225 mm nominal extend stroke down to 205 mm on-site. The stop sets end position and is not a load lock.
