This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X250-40, 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 SUJ32X250-40
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X250-40 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 SAUJ32X250-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X250-40
The AirTAC SUJ32X250-40 is a discontinued double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40 mm on-site. Its nominal 250 mm stroke is the maximum, yielding a usable 210-250 mm extend window.
Because the SUJ line is end-of-life, the direct replacement is the SAUJ32X250-40, which retains the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades sensing to current CMSG/DMSG/EMSG switches, whereas this legacy model used CS1-B/DS1-B sensors. As a non-magnetic SKU, this specific cylinder cannot accept a switch. The external stop sets end position only; it is not a lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X250-40 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 SAUJ32X250-40 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 SUJ32X250-40 Is Used
Custom Stroke Dwell Jigs
Trimming the extend stroke by up to 40 mm on-site allows operators to fine-tune dwell positions in light assembly jigs without machining custom spacers.
Variable Length Reject Pushers
The 210-250 mm usable stroke window lets a single 32 mm bore cylinder accommodate varying product lengths on a conveyor line by adjusting the end stop.
Adjustable Stop Fences
Using the external stop screw to set precise end positions simplifies the alignment of moving stop fences in packaging lanes that require frequent format changes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X250-40 with the SAUJ32X250-40
To replace the discontinued SUJ32X250-40, specify the SAUJ32X250-40 direct, which keeps the 1/8" port, M10x1.25 rod thread, and 21 mm cushions. Choose the 40 mm adjust window when you need up to 40 mm of on-site extend trimming. For stroke lengths of 300 mm or more, carefully evaluate side-load moments. If you require position sensing, note this non-magnetic version cannot support switches; the SAUJ requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X250-40
- ✓ 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 SUJ32X250-40 FAQ
Yes, the SUJ32X250-40 is discontinued. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw provides a 40 mm adjustment window, meaning the 250 mm nominal extend stroke can be shortened to 210 mm on-site.
