This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X250-100, 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 SUJ32X250-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X250-100 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 SAUJ32X250-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X250-100
The AirTAC SUJ32X250-100 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 150-250 mm window from the 250 mm nominal maximum. The stop sets end position only; it is not a load lock, so use an external rod lock for held loads.
The direct replacement is the SAUJ32X250-100, retaining the same compact profile body, force, and SC-series FA/LB mounting. This base SKU lacks a magnet and cannot take a switch. The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used here.

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 SAUJ32X250-100 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 SUJ32X250-100 Is Used
Custom Stroke Dwell
Trimming the extend by up to 100 mm on-site allows precise positioning of machining stops without machining custom spacers.
Variable Length Sorting
Adjusting the extend stroke from 150 to 250 mm accommodates changing package sizes on a sorting line.
Adjustable Ejector Push
Tuning the end position on-site lets an ejection mechanism adapt to varying product widths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X250-100 with the SAUJ32X250-100
To replace this discontinued SUJ32X250-100, order the direct replacement SAUJ32X250-100; it matches the 32 mm bore, 250 mm max stroke, 1/8" port, and FA/LB mounts. Choose the 100 mm adjust window when you need on-site tuning from 150 to 250 mm. Because this non-magnetic SKU cannot take a switch, specify an -S SAUJ with CMSG/DMSG/EMSG sensors if position feedback is required. For this 250 mm stroke, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X250-100
- ✓ 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 SUJ32X250-100 FAQ
Yes, the SUJ32X250-100 is discontinued. The direct replacement is the SAUJ32X250-100, which matches the 32 mm bore, 250 mm stroke, 1/8" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw window is 100 mm, allowing you to shorten the 250 mm nominal extend stroke down to 150 mm on-site. The stop sets end position only and is not a load lock.
