This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X25-10, 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 SUJ100X25-10
The AirTAC SUJ Adjustable Cylinder SUJ100X25-10 is a double-acting profile-type standard cylinder with a Ø100mm bore and 25mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X25-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X25-10
The AirTAC SUJ100X25-10 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, giving a usable 15-25 mm stroke window from the 25 mm nominal maximum. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions at each end.
The direct replacement is the SAUJ100X25-10, matching the bore, stroke, force, port, and SC-series FA/LB mounting. Upgrading to the SAUJ moves you to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B switches. Note this non-magnet SKU cannot take a switch, and the stop screw sets end position but is not a load lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X25-10 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 SAUJ100X25-10 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 SUJ100X25-10 Is Used
Short-Stroke Clamping
Trimming the extend stroke by up to 10 mm on-site allows precise clamping of varied part thicknesses without re-engineering the fixture.
Transfer Diverter Setup
Field-tuning the 15-25 mm extend window lets operators dial in the exact diverter finger position to meet varying product widths on the line.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X25-10 with the SAUJ100X25-10
Choose the 10 mm adjust window when you need precise end-position tuning between 15 and 25 mm without adding an external stop. Because this is a non-magnet SKU, it cannot accept a sensor; if sensing is required, select the -S SAUJ variant for CMSG/DMSG/EMSG compatibility. The external stop sets end position but is not a lock; for held loads, specify an external rod lock or pilot-operated check valve. Since the 25 mm stroke is under 300 mm, side-load rod deflection is minimal.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X25-10
- ✓ 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 SUJ100X25-10 FAQ
Yes, the SUJ100X25-10 is discontinued. The direct replacement is the SAUJ100X25-10, which matches the 100 mm bore, 25 mm stroke, 1/2 inch port, and FA/LB mounting. The SAUJ also supports current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
This double-acting double-rod cylinder has a 10 mm adjust window, allowing you to shorten the extend stroke from the 25 mm maximum down to 15 mm on-site. The stop screw sets end position but is not a load lock.
