This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X25-30S, 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 SUJ32X25-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X25-30S is a double-acting profile-type standard cylinder with a Ø32mm bore and 25mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X25-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X25-30S
The AirTAC SUJ32X25-30S is a discontinued double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site. With a nominal 25 mm stroke, this allows a usable extend window down to 0 mm for precise field tuning. The direct replacement is the SAUJ32X25-30S, which matches the bore, stroke, force, and SC-series FA/LB mounting.
The SAUJ upgrade transitions from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches while retaining the compact profile barrel that is shorter than an ISO 15552 cylinder of the same size. The external stop sets the 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 SAUJ32X25-30S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUJ32X25-30S 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 SUJ32X25-30S Is Used
Dialing in Clamp Position
Adjusting the extend stop on-site by up to 30 mm to set the exact clamping contact point for varying workpiece heights without swapping cylinders.
Short-Stroke Forming
Trimming the 25 mm extend stroke down to a precise sub-stroke for light pressing or forming tasks where the bottom dead center must be tuned per tool.
Sensor Actuation Timing
Fine-tuning the physical extend endpoint to trigger legacy CS1-B/DS1-B (or upgraded CMSG/DMSG/EMSG) switches at the exact moment a parts diverter needs to actuate.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X25-30S with the SAUJ32X25-30S
To replace the discontinued SUJ32X25-30S, order the exact direct replacement SAUJ32X25-30S, which preserves the 32 mm bore, 25 mm nominal stroke, 30 mm adjust window, and 1/8" port. Choose the 30 mm adjust window when you need to dial in the extend stroke on-site rather than using a fixed SAU plus an external stop. Mounting remains compatible with AirTAC SC-series FA and LB brackets. Because this unit has the -S magnet, upgrade your position sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. For any application with a stroke of 300 mm or longer, verify the rod end supports to manage side-load moments.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X25-30S
- ✓ 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 SUJ32X25-30S FAQ
Yes, the AirTAC SUJ32X25-30S is discontinued. The direct replacement is the SAUJ32X25-30S. It matches the 32 mm bore, 25 mm nominal stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. You simply update the -S position sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The external stop screw provides a 30 mm adjust window, allowing you to trim the 25 mm nominal extend stroke down to 0 mm on-site. The stop sets end position but is not a load lock.
