This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X250-75S, 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 SUJ100X250-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X250-75S 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 SAUJ100X250-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X250-75S
The AirTAC SUJ100X250-75S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 175-250 mm extend window from the 250 mm nominal maximum. It features a 1/2" port, a 25 mm rod, M20x1.5 rod thread, and 29 mm adjustable air cushions. This SUJ model is discontinued; the direct replacement is the SAUJ100X250-75S, which preserves the bore, stroke, force, port, and FA/LB mounting.
The stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock for held loads. The SAUJ upgrade also adopts current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here, and the compact profile barrel is notably shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X250-75S 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 SAUJ100X250-75S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SUJ Adjustable Cylinder SUJ100X250-75S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×250 | Stroke length in mm. |
| -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 SUJ100X250-75S Is Used
Variable Depth Pressing
Allows operators to dial in the exact extend stop for inserting fixtures to varying depths without reprogramming the motion controller.
Adjustable Transfer Stops
Enables on-the-fly extend stroke reduction to accommodate different package sizes on a single material handling line.
Custom Position Diverters
Provides a tuned mechanical end position for routing goods, ensuring precise physical stops where sensor-only control is insufficient.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X250-75S with the SAUJ100X250-75S
To replace the discontinued SUJ100X250-75S, order the direct replacement SAUJ100X250-75S, which matches the 100 mm bore, 250 mm stroke, 75 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 75 mm adjust window if your application requires field tuning the extend stroke down to 175 mm; the stop screw sets end position but is not a lock. 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 strokes of 300 mm or longer, verify side-load limits to prevent excessive guide wear. Mounting compatibility is strictly with the AirTAC SC series.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X250-75S
- ✓ 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 SUJ100X250-75S FAQ
Yes, the SUJ100X250-75S is discontinued. The direct replacement is the SAUJ100X250-75S, which matches the 100 mm bore, 250 mm stroke, 75 mm adjust window, 1/2" port, and FA/LB mounting. You will need to upgrade the switches from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.
The external stop screw window is 75 mm, allowing you to shorten the 250 mm nominal extend stroke down to 175 mm on-site. The stop sets end position but is not a load lock.
