This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X500-40S, 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 SUJ32X500-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X500-40S is a double-acting profile-type standard cylinder with a Ø32mm bore and 500mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X500-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X500-40S
The AirTAC SUJ32X500-40S 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 460-500 mm window from the 500 mm nominal maximum. The stop screw strictly sets the end position; it is not a load lock, so add an external rod lock for held loads.
You must migrate to the direct replacement SAUJ32X500-40S, which preserves the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X500-40S 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 SAUJ32X500-40S 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 SUJ32X500-40S Is Used
Variable Depth Boring
Adjusting the extend stroke on-site by up to 40 mm allows a machining fixture to tune boring depth precisely without swapping the entire cylinder.
Adjustable Transfer Stops
Trimming the extend stroke lets a conveyor diverting gate accommodate varying package sizes on the fly, ensuring packages align correctly.
Variable Stroke Sealing
A sealing head can fine-tune its downward extend distance to match different container heights, preventing crush damage during the packaging process.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X500-40S with the SAUJ32X500-40S
To replace this discontinued unit, order the SAUJ32X500-40S; it is a direct swap retaining the 32 mm bore, 500 mm stroke, 1/8" port, and FA/LB mounting. Choose the 40 mm adjust window if your field stroke tuning requires trimming the extend by up to 40 mm on-site. Because this unit has an -S magnet, you must upgrade your legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. At 500 mm stroke, mind the side-load and rod-bending limits; use external guides to prevent premature seal wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X500-40S
- ✓ 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 SUJ32X500-40S FAQ
Yes, the SUJ32X500-40S is discontinued. You must upgrade your sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG.
The external stop screw provides a 40 mm adjust window, allowing you to trim the extend stroke from the 500 mm maximum down to 460 mm on-site.
