This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X100-20S, 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 SUJ32X100-20S
The AirTAC SUJ Adjustable Cylinder SUJ32X100-20S is a double-acting profile-type standard cylinder with a Ø32mm bore and 100mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X100-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X100-20S
The AirTAC SUJ32X100-20S 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 80-100 mm extend out of the 100 mm nominal maximum. The compact extruded aluminum barrel is shorter than a standard cylinder of the same bore. This discontinued model is replaced direct by the SAUJ32X100-20S, retaining the 32 mm bore, 1/8" port, and M10x1.25 rod thread.
The SAUJ upgrade keeps the FA/LB mounting but moves to current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used here. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X100-20S 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 SAUJ32X100-20S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×100 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ32X100-20S Is Used
Variable Depth Drilling
Adjusting the extend stroke on-site by up to 20 mm allows precise depth control for drilling operations without changing the entire cylinder setup.
Variable Pitch Sorting
Trimming the extend stroke dynamically accommodates different product lengths on a sorting line, ensuring accurate pusher positioning.
Adjustable Carton Sealing
Fine-tuning the extend end position by up to 20 mm adapts the sealing jaw stroke to varying carton heights on the fly.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X100-20S with the SAUJ32X100-20S
To replace the discontinued SUJ32X100-20S, order the exact direct replacement SAUJ32X100-20S, which preserves the 32 mm bore, 100 mm nominal 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 80 and 100 mm without adding an external stop. Because this unit has the -S magnet, you must migrate from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors on the SAUJ. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding. Remember the stop screw only sets end position and does not hold the load on air loss.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X100-20S
- ✓ 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 SUJ32X100-20S FAQ
Yes, the SUJ32X100-20S is discontinued. The direct replacement is the SAUJ32X100-20S, which matches the 32 mm bore, 100 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. You will need to upgrade the sensors from legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG switches.
The external stop screw provides a 20 mm adjust window, allowing you to shorten the 100 mm nominal extend stroke down to 80 mm on-site. The stop sets end position but is not a load lock.
