This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X450-40, 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 SUJ32X450-40
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X450-40 is a double-acting profile-type standard cylinder with a Ø32mm bore and 450mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X450-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X450-40
The AirTAC SUJ32X450-40 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 410-450 mm window from the 450 mm nominal maximum.
The direct replacement is the SAUJ32X450-40, matching the bore, stroke, force, port, and FA/LB mounting. Upgrading to the SAUJ moves you to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B type. 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 SAUJ32X450-40 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 SAUJ32X450-40 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 SUJ32X450-40 Is Used
Variable Pitch Pushing
Tuning the extend stroke on-site by up to 40 mm to push parts of varying widths into a machining station without swapping the entire cylinder.
Adjustable Diverting
Actuating a diverter arm where the exact end position must be dialed in 410-450 mm to accommodate changes in conveyor lane width.
Variable Depth Sealing
Driving a sealing head that needs precise field adjustment to compress packages of slightly different heights without reprogramming controls.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X450-40 with the SAUJ32X450-40
To replace this discontinued SUJ32X450-40, order the SAUJ32X450-40 direct. If you need to size both ways, the adjacent bores are 40 mm and 25 mm (though 25 mm is outside the SUJ range, use SAU25). Choose the 40 mm adjust window if your on-site extend stroke needs trimming between 410 and 450 mm. This SKU has no magnet and cannot take a switch; the SAUJ uses CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B. Mounting is SC-series compatible (FA, LB). Because the stroke is 450 mm, add external guides to prevent rod bending and manage side loads. The stop screw sets end position but does not lock the load on air loss.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X450-40
- ✓ 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 SUJ32X450-40 FAQ
Yes, the SUJ32X450-40 is discontinued. The direct replacement is the SAUJ32X450-40, which shares the same 32 mm bore, 450 mm stroke, 1/8" port, and FA/LB mounting. The SAUJ upgrades you to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B.
It is double-acting double-rod with a 40 mm adjust window, allowing you to trim the extend stroke from the 450 mm maximum down to 410 mm on-site. The stop screw sets end position only and is not a load lock.
