This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X225-100S, 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 SUJ100X225-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X225-100S 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 SAUJ100X225-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X225-100S
The AirTAC SUJ100X225-100S 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 extend window from the 225 mm nominal maximum. It features a 1/2" port, a Ø25 mm piston rod with an M20x1.5 thread, and 29 mm adjustable air cushions at each end.
Because the SUJ series is discontinued, the direct replacement is the SAUJ100X225-100S, which preserves the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade shifts sensing to current CMSG/DMSG/EMSG switches from the legacy CS1-B/DS1-B used here. Remember the stop screw sets end position only; it is not a load lock, so add an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X225-100S 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 SAUJ100X225-100S 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 SUJ100X225-100S Is Used
Variable Pitch Indexing
Pushing parts into a press where the extend stop must be tuned on-site across a 125-225 mm range to accommodate different material thicknesses without swapping cylinders.
Adjustable Diverter Gate
Actuating a routing flap on a packaging line where the 100 mm trim window allows operators to reposition the end-stop for changing box sizes on the fly.
Tiered Pallet Positioning
Driving a lift pin into pallets of varying heights, using the external stop screw to set precise extend endpoints for each pallet tier.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X225-100S with the SAUJ100X225-100S
To replace this discontinued model, specify the SAUJ100X225-100S, which is a direct swap matching the 100 mm bore, 225 mm stroke, 1/2" port, and FA/LB mounting. The 100 mm adjust window is ideal if your end-stop varies widely; choose a smaller window if you only need fine trimming. Because this unit has an -S magnet, note that the SAUJ uses CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For this 225 mm stroke, side-load is minimal, but for any stroke >=300 mm ensure guide rails carry the lateral load. The stop screw sets end position only and does not lock the load; use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X225-100S
- ✓ 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 SUJ100X225-100S FAQ
Yes, the SUJ100X225-100S is discontinued. The direct replacement is the SAUJ100X225-100S, which matches the 100 mm bore, 225 mm stroke, 1/2" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw provides a 100 mm trim window, allowing the extend stroke to be shortened from the 225 mm nominal maximum down to 125 mm on-site.
