This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X80-20S, 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 SUJ32X80-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X80-20S is a double-acting profile-type standard cylinder with a Ø32mm bore and 80mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X80-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X80-20S
The AirTAC SUJ32X80-20S is a double-acting, double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 60-80 mm extend from the 80 mm nominal maximum. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.
This SUJ model is discontinued and the direct replacement is the SAUJ32X80-20S, matching the 32 mm bore, 80 mm stroke, force, and FA/LB mounting. The SAUJ upgrade switches legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches while retaining the compact profile barrel.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X80-20S 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 SAUJ32X80-20S 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 SUJ32X80-20S Is Used
Variable Pitch Indexing
Dialing in the exact extend stop on a 32 mm bore actuator to tune part ejection distance on the fly without swapping mechanical spacers.
Adjustable Diverter Gate
Setting a precise 60 to 80 mm push stroke to deflect varying package sizes on a line, using the external screw to tune the gate position.
Tunable Pusher Stops
Trimming the extend stroke by up to 20 mm on-site to accommodate different carton depths at a packing station without reprogramming the PLC.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X80-20S with the SAUJ32X80-20S
To replace the discontinued SUJ32X80-20S, order the direct replacement SAUJ32X80-20S, which keeps the 32 mm bore, 80 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 20 mm adjust window if you need on-site extend tuning between 60 and 80 mm; for fixed stops, a standard SAU cylinder with an external stop is an alternative, but the SAUJ provides a cleaner integrated solution. Because this model has the -S magnet, you must migrate from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X80-20S
- ✓ 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 SUJ32X80-20S FAQ
Yes, the AirTAC SUJ32X80-20S is discontinued. The direct replacement is the SAUJ32X80-20S, which matches the 32 mm bore, 80 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. You will need to upgrade your position sensors from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG series.
The external stop screw provides a 20 mm adjust window, allowing you to shorten the 80 mm nominal extend stroke down to 60 mm on-site. Note that the stop sets end position only; it is not a load lock.
