This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X400-10, 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 SUJ100X400-10
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X400-10 is a double-acting profile-type standard cylinder with a Ø100mm bore and 400mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X400-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X400-10
The AirTAC SUJ100X400-10 is a double-acting double-rod profile cylinder with an adjustable stroke, allowing you to trim the extend stroke by up to 10 mm on-site for a usable 390-400 mm range. The direct replacement is the SAUJ100X400-10, matching the 1/2" port, M20x1.5 rod thread, and 29 mm adjustable cushions.
The SAUJ upgrade transitions sensing to current CMSG/DMSG/EMSG switches from the legacy CS1-B/DS1-B, though this specific non-magnet SKU cannot accept a switch. The external stop screw sets the end position but is not a load lock; the cylinder drifts on air loss, requiring an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X400-10 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 SAUJ100X400-10 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 SUJ100X400-10 Is Used
Press Fit Tuning
Trimming the 10 mm extend window lets operators dial in the exact bottoming position for pressing bearings without machining hard stops.
Divertor End Adjustment
Field-tuning the extend stroke ensures a diverting gate meets varying product sizes perfectly on the line.
Pallet Stop Positioning
Fine-tuning the extend stop screw accommodates slight pallet length variations in handling systems.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X400-10 with the SAUJ100X400-10
To replace the discontinued SUJ100X400-10, order the direct replacement SAUJ100X400-10, retaining the 100 mm bore, 400 mm stroke, 10 mm adjust window, FA/LB mounting, and 1/2" port. Choose the 10 mm adjust window when you need precise field tuning of the extend end position. Because this is a non-magnet model, it cannot take a sensor; if sensing is needed, select an SAUJ with the -S suffix and use CMSG/DMSG/EMSG switches. For the 400 mm stroke, use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X400-10
- ✓ 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 SUJ100X400-10 FAQ
Yes, the SUJ100X400-10 is discontinued. The direct replacement is the SAUJ100X400-10, which matches the 100 mm bore, 400 mm stroke, 10 mm adjust window, 1/2" port, and FA/LB mounting.
The external stop screw offers a 10 mm adjust window, making the usable extend stroke 390-400 mm.
