This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X250-10S, 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 SUJ100X250-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X250-10S is a double-acting profile-type standard cylinder with a Ø100mm bore and 250mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X250-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X250-10S
The AirTAC SUJ100X250-10S is a double-acting double-rod profile cylinder with a 100mm bore and 250mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 10mm on-site, giving a usable 240-250mm window for precise end-position tuning. The 1/2" port and 29mm adjustable cushions manage the energy of this large-bore actuator.
This SUJ model is discontinued; the direct replacement is the SAUJ100X250-10S, matching the bore, stroke, force, 1/2" port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors (this unit uses legacy CS1-B/DS1-B switches via its -S magnet). The stop screw sets 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 SAUJ100X250-10S 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 SAUJ100X250-10S 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 SUJ100X250-10S Is Used
Press Fit Tuning
Trimming the extend stroke by up to 10mm on-site allows precise bottoming force for press-fitting bearings without machining hard stops.
Divertor Positioning
Field-tuning the 240-250mm extend window lets maintenance teams align divertor gates precisely to varying product sizes on the line.
Pallet Stop Calibration
Adjusting the extend end-position compensates for pallet thickness variations, ensuring exact stopping points without reprogramming controls.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X250-10S with the SAUJ100X250-10S
To replace the discontinued SUJ100X250-10S, specify the SAUJ100X250-10S directly—it is a direct match for the 100mm bore, 250mm stroke, 10mm adjust window, 1/2" port, and FA/LB mounts. Choose the 10mm adjust window if you need minor on-site extend trimming rather than a fixed stop. Note the -S sensor change: migrate from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. Mounting is compatible with the AirTAC SC series only. For strokes of 300mm or longer, verify side-load guidance to prevent rod bearing wear. Remember the stop screw only sets end position; it does not hold loads on air loss.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X250-10S
- ✓ 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 SUJ100X250-10S FAQ
Yes, the SUJ100X250-10S is discontinued. The direct replacement is the SAUJ100X250-10S, which matches the 100mm bore, 250mm stroke, 10mm 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 allows trimming the extend stroke by up to 10mm on-site (usable 240-250mm). The stop sets end position only; it is not a load lock.
