This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X250-20, 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 SUJ32X250-20
The AirTAC SUJ Adjustable Cylinder SUJ32X250-20 is a double-acting profile-type standard cylinder with a Ø32mm bore and 250mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X250-20, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X250-20
The AirTAC SUJ32X250-20 is a discontinued double-acting double-rod profile cylinder with a 32mm bore and 250mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 20mm on-site, yielding a usable 230-250mm window. This compact extruded barrel is shorter than an ISO 15552 cylinder of the same bore.
Because this SKU lacks a magnet, it cannot take a magnetic switch. It is discontinued; the direct replacement is the SAUJ32X250-20, which retains the bore, stroke, 1/8" port, and FA/LB mounting. The SAUJ upgrades sensing to current CMSG/DMSG/EMSG switches (the SUJ used legacy CS1-B/DS1-B). The stop screw sets end position only; it is not a load lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X250-20 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 SAUJ32X250-20 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 SUJ32X250-20 Is Used
Adjustable End Stop Forming
Pinpoints the extend end position for light forming tasks, allowing 20mm of on-site stroke tuning to accommodate material thickness variations without re-mounting the cylinder.
Variable Length Diverter
Acts as a diverter gate on a conveyor where product lengths change, using the external stop screw to set the exact 230-250mm extend reach required for each run.
Adjustable Depth Pusher
Pushes bins to variable stop depths in a compact packing cell, relying on the 20mm adjust window to fine-tune the final resting position on the fly.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X250-20 with the SAUJ32X250-20
To replace the discontinued SUJ32X250-20, order the direct replacement SAUJ32X250-20; the 32mm bore, 250mm max stroke, 20mm adjust window, 1/8" port, and FA/LB mounting are unchanged. Choose the 20mm adjust window when you need field tuning of the extend end position; the SAUJ beats a fixed SAU plus external stop by integrating the screw cleanly. Because this non-magnet SKU cannot take a switch, the SAUJ upgrade lets you use current CMSG/DMSG/EMSG sensors. For stroke lengths >=300mm, verify side-load limits to prevent rod binding. The stop screw is not a lock; use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X250-20
- ✓ 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 SUJ32X250-20 FAQ
Yes, the AirTAC SUJ32X250-20 is discontinued. The direct replacement is the SAUJ32X250-20, which matches the 32mm bore, 250mm stroke, 20mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw provides a 20mm adjust window, shortening the 250mm nominal extend stroke to a usable 230-250mm on-site. The stop sets end position and is not a load lock.
