This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X125-40, 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 SUJ32X125-40
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X125-40 is a double-acting profile-type standard cylinder with a Ø32mm bore and 125mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X125-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X125-40
The AirTAC SUJ32X125-40 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 85-125 mm range from the 125 mm nominal maximum. Because the stop screw only sets the end position, it is not a load lock; use an external rod lock for held loads.
This SUJ model is discontinued; the direct replacement is the SAUJ32X125-40, matching the bore, stroke, force, port, and FA/LB mounting. Upgrading to the SAUJ moves you to current CMSG/DMSG/EMSG sensors, as this legacy unit used CS1-B/DS1-B switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X125-40 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 SAUJ32X125-40 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 SUJ32X125-40 Is Used
Variable Pitch Feed
Tuning the extend stroke by up to 40 mm on-site allows a 32 mm bore feed cylinder to hit changing material lengths without swapping the entire actuator.
Adjustable Diverter Gate
Field-trimming the extend end position lets a diverting mechanism accommodate varying package sizes on the fly while using the full 125 mm stroke when needed.
Variable Depth Sealing
An external stop screw provides precise depth control for sealing heads, allowing quick 85-125 mm adjustments for different container heights.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X125-40 with the SAUJ32X125-40
To replace the discontinued SUJ32X125-40, order the direct replacement SAUJ32X125-40, which preserves the 32 mm bore, 125 mm nominal stroke, 40 mm adjust window, and 1/8" port. Choose the 40 mm adjust window if your end-position tuning requires a 85-125 mm extend range. Mounting uses basic, FA, or LB brackets (SC-series compatible). Because this non-magnet SKU lacks a switch, you cannot mount sensors; the SAUJ upgrade supports CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify your side-load limits to prevent guide wear. The stop screw sets end position but does not lock the load on air loss—add an external rod lock for vertical holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X125-40
- ✓ 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 SUJ32X125-40 FAQ
Yes, the SUJ32X125-40 is discontinued. The direct replacement is the SAUJ32X125-40, which matches the 32 mm bore, 125 mm stroke, 40 mm adjust window, and 1/8" port. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw trims the extend stroke by up to 40 mm on-site, giving a usable 85-125 mm range. The stop sets end position and is not a load lock.
