This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X25-30S, 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 SUJ100X25-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X25-30S 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 SAUJ100X25-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X25-30S
The AirTAC SUJ100X25-30S is a discontinued double-acting double-rod profile cylinder with a 25 mm nominal extend stroke and a 30 mm external stop screw window, letting you trim the extend stroke on-site down to zero. It features a 1/2 inch port, M20x1.5 rod thread, and 29 mm adjustable air cushions. The direct replacement is the SAUJ100X25-30S, which retains the exact bore, stroke, force, port, and FA/LB mounting.
The stop screw sets the end position but is not a load lock; without live air the piston drifts, so use an external rod lock for held loads. The SAUJ upgrade switches legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches while keeping the compact profile barrel shorter than standard cylinders.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X25-30S 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 SAUJ100X25-30S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 100 | Bore size in mm. |
| ×25 | 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 SUJ100X25-30S Is Used
Short-Stroke Clamping
Adjustable end-position clamping of heavy castings where a 25 mm nominal stroke needs precise 0-25 mm field trimming to avoid crushing the workpiece.
Transfer Diverter Stops
Actuating diverter gates on conveyor lines where the exact extend stop point must be dialed in on-site to match varying package dimensions.
Pallet Positioning
Indexing pallets into a test cell, using the external stop screw to fine-tune the 25 mm extend stroke for precise sensor alignment.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X25-30S with the SAUJ100X25-30S
To replace the discontinued SUJ100X25-30S, order the direct replacement SAUJ100X25-30S, which matches the 100 mm bore, 25 mm stroke, 30 mm adjust window, 1/2 inch port, and FA/LB mounting. Choose the 30 mm adjust window when you need field-tuning of the extend stroke; the stop screw sets end position but is not a lock. Because this unit has the -S magnet, upgrade your position sensing from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X25-30S
- ✓ 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 SUJ100X25-30S FAQ
Yes, the SUJ100X25-30S is discontinued. The direct replacement is the SAUJ100X25-30S, offering the same 100 mm bore, 25 mm stroke, 30 mm adjust window, 1/2 inch port, and FA/LB mounting. You only need to upgrade the sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG.
The external stop screw window is 30 mm, allowing you to trim the 25 mm nominal extend stroke down to zero on-site. The stop sets end position but is not a load lock.
