This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X400-40, 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 SUJ32X400-40
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X400-40 is a double-acting profile-type standard cylinder with a Ø32mm bore and 400mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X400-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X400-40
The AirTAC SUJ32X400-40 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 360-400 mm stroke from the 400 mm nominal maximum. This compact extruded barrel is shorter than an ISO 15552 cylinder of the same bore. The SUJ line is discontinued; the direct replacement is the SAUJ32X400-40, matching the 32 mm bore, 1/8" port, and FA/LB mounting.
The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. This non-magnet SKU cannot take a sensor, whereas the SAUJ upgrade uses current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X400-40 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 SAUJ32X400-40 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 SUJ32X400-40 Is Used
Variable Pitch Indexing
Allows on-site extend stroke tuning up to 40 mm to alter part pitch without swapping cylinders when product sizes change.
Adjustable Diverter Gate
Provides field-adjustable gate extension to accommodate varying package widths on a single profile cylinder body.
Variable Depth Forming
Enables precise 360-400 mm extend adjustments for carton forming or sealing heads requiring different material depths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X400-40 with the SAUJ32X400-40
To replace the discontinued SUJ32X400-40, order the direct replacement SAUJ32X400-40, keeping the 32 mm bore, 400 mm nominal stroke, 40 mm adjust window, and 1/8" port. Choose the 40 mm adjust window if your field tuning requires trimming the extend stroke by up to 40 mm. Mounting is compatible with AirTAC SC series FA and LB brackets. Because this SKU lacks a magnet, it cannot take a sensor; the SAUJ upgrade uses CMSG/DMSG/EMSG switches instead of legacy CS1-B/DS1-B. At a 400 mm stroke, support external guides to prevent rod bending and side-load damage. The stop screw sets end position but does not lock the load on air loss.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X400-40
- ✓ 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 SUJ32X400-40 FAQ
Yes, the SUJ32X400-40 is discontinued. The direct replacement is the SAUJ32X400-40, matching the 32 mm bore, 400 mm stroke, 40 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw window is 40 mm, allowing you to trim the 400 mm nominal extend stroke down to 360 mm on-site. The stop sets end position but is not a load lock.
