This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X400-40S, 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 SUJ32X400-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X400-40S 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 SAUJ32X400-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X400-40S
The AirTAC SUJ32X400-40S is a double-acting double-rod profile cylinder with a 32mm bore and 400mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 40mm on-site, yielding a usable 360-400mm window. The stop sets the end position but is not a load lock.
The direct replacement is the SAUJ32X400-40S, matching the bore, stroke, force, and SC-series FA/LB mounting. Upgrading brings current CMSG/DMSG/EMSG sensor compatibility. Note that a plain cylinder drifts on air loss; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X400-40S 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 SAUJ32X400-40S 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 SUJ32X400-40S Is Used
Variable Pitch Pushing
Feeding parts on a line where the extend stop requires field tuning up to 40mm to accommodate different product lengths without swapping cylinders.
Adjustable Diverter Gate
Actuating a routing gate that needs precise 360-400mm extend endpoints set on-site to handle varying package widths on the fly.
Custom Length Stopping
Providing a hard stop for materials where the final position is dialed in via the external screw during installation and commissioning.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X400-40S with the SAUJ32X400-40S
To replace the discontinued SUJ32X400-40S, specify the SAUJ32X400-40S direct, keeping the 32mm bore, 400mm stroke, 1/8" port, and FA/LB mounts. The 40mm adjust window is ideal when exact extend endpoints vary by up to 40mm, avoiding the need for a fixed SAU plus external stop. The -S suffix means the SAUJ requires current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. Because the 400mm stroke is long, account for side-load and rod-bending by using external guides to prevent premature wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X400-40S
- ✓ 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 SUJ32X400-40S FAQ
Yes, the SUJ32X400-40S is discontinued. The direct replacement is the SAUJ32X400-40S, which shares the same 32mm bore, 400mm stroke, 1/8" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw provides a 40mm adjustment window, allowing the extend stroke to be shortened from the 400mm maximum down to 360mm on-site.
