This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X275-40, 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 SUJ32X275-40
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X275-40 is a double-acting profile-type standard cylinder with a Ø32mm bore and 275mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X275-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X275-40
The AirTAC SUJ32X275-40 is a 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, yielding a usable 235-275 mm extension from the 275 mm nominal maximum. This compact profile barrel is shorter than an ISO 15552 cylinder of the same bore.
This SUJ model is discontinued; the direct replacement is the SAUJ32X275-40, matching the bore, stroke, force, port and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches. As a plain non-magnetic cylinder, this SKU cannot take a switch. The stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X275-40 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 SAUJ32X275-40 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 SUJ32X275-40 Is Used
Custom Ejector Pins
Trimming the extend stroke by up to 40 mm on-site allows exact ejection of parts from fixtures without machining custom spacers.
Variable Transfer Stops
Adjusting the end position on the fly accommodates different package sizes on a 32 mm profile cylinder transfer line.
Adjustable Pusher Arms
Dialing in the 235-275 mm stroke window ensures light 20 kg loads are pushed precisely into packing lanes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X275-40 with the SAUJ32X275-40
To replace the discontinued SUJ32X275-40, order the direct replacement SAUJ32X275-40, which preserves the 32 mm bore, 275 mm stroke, 1/8" port and FA/LB mounting. If migrating, the SAUJ takes current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. Choose the 40 mm adjust window if you need to trim the extend stroke on-site between 235 and 275 mm. Note that at a 275 mm stroke, side-load alignment must be carefully controlled to prevent rod binding. Because this SKU lacks a magnet, it cannot accept a sensor; if sensing is needed, select an -S SAUJ model.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X275-40
- ✓ 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 SUJ32X275-40 FAQ
Yes, the SUJ32X275-40 is discontinued. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw provides a 40 mm adjust window, allowing you to shorten the extend stroke from 275 mm down to 235 mm on-site. The stop sets end position only and is not a load lock.
