This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X225-10S, 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 SUJ100X225-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X225-10S 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 SAUJ100X225-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X225-10S
The AirTAC SUJ100X225-10S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 215-225 mm stroke. It features a 1/2" port, a 25 mm rod, and 29 mm adjustable cushions. The stop screw sets the end position but is not a lock; loads drift on air loss, so use an external rod lock for holding.
This SUJ model is discontinued; the direct replacement is the SAUJ100X225-10S, matching the bore, stroke, force, 1/2" port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors (this unit used legacy CS1-B/DS1-B switches for its -S magnet).

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X225-10S 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 SAUJ100X225-10S 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 SUJ100X225-10S Is Used
Press Fit Tuning
Trimming the extend stroke by up to 10 mm on-site allows precise bottoming force for light press-fit operations without machining hard stops.
Transfer Diverter
Adjusting the extend end position lets operators fine-tune a diverter gate's reach on a packaging conveyor to handle varied product widths.
Pallet Stopper
A 10 mm external stop adjustment provides exact positioning for a pallet stopping mechanism, accommodating slight pallet size variations.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X225-10S with the SAUJ100X225-10S
To replace the discontinued SUJ100X225-10S, order the direct replacement SAUJ100X225-10S, which preserves the 100 mm bore, 225 mm max stroke, 10 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 10 mm adjust window if you need fine end-position tuning rather than a large stroke reduction. The -S suffix means a piston magnet is present; you must switch from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors on the SAUJ. For this 225 mm stroke, verify side-load limits per the datasheet.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X225-10S
- ✓ 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 SUJ100X225-10S FAQ
Yes, the SUJ100X225-10S is discontinued. The direct replacement is the SAUJ100X225-10S, which matches the 100 mm bore, 225 mm stroke, 10 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw window is 10 mm, allowing you to shorten the 225 mm maximum extend stroke down to 215 mm on-site. The stop sets end position and is not a load lock.
