This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X300-100S, 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 SUJ32X300-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X300-100S is a double-acting profile-type standard cylinder with a Ø32mm bore and 300mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X300-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X300-100S
The AirTAC SUJ32X300-100S is a double-acting double-rod profile cylinder with a 32 mm bore and 1/8" port, engineered for on-site stroke tuning. An external stop screw lets you trim the extend stroke by up to 100 mm, yielding a usable 200-300 mm extension from the 300 mm nominal maximum. The stop sets the end position but is not a load lock; use an external rod lock for held loads.
This SUJ32X300-100S unit is discontinued and the direct replacement is the SAUJ32X300-100S, retaining the same profile body, force, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used here.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X300-100S 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 SAUJ32X300-100S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SUJ Adjustable Cylinder SUJ32X300-100S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 32 | Bore size in mm. |
| ×300 | 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 SUJ32X300-100S Is Used
Variable Pitch Indexing
Dialing in the extend stroke by up to 100 mm on-site allows a single 32 mm bore actuator to push parts into a machine at varying distances without swapping the entire cylinder.
Adjustable Transfer Stops
Trimming the extend stroke from 300 mm down to 200 mm lets operators reposition a conveyor divert stop exactly where different product sizes require, tuning the endpoint on the fly.
Variable Depth Sealing
An external stop screw provides precise mechanical depth control for sealing heads, allowing the 300 mm nominal stroke to be shortened on-site to accommodate varying package heights.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X300-100S with the SAUJ32X300-100S
To replace the discontinued SUJ32X300-100S, order the direct replacement SAUJ32X300-100S, which matches the 32 mm bore, 300 mm max stroke, 100 mm adjust window, 1/8" port, and FA/LB mounting. If migrating, note the -S sensor change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. Choose the 100 mm adjust window if your end-stop position varies significantly on-site. Because the stroke is 300 mm, ensure external guides are used to prevent rod bending and manage side loads, as long strokes amplify deflection.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X300-100S
- ✓ 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 SUJ32X300-100S FAQ
Yes, the AirTAC SUJ32X300-100S is discontinued. The direct replacement is the SAUJ32X300-100S, which shares the same 32 mm bore, 300 mm max stroke, 100 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ replacement uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
This double-acting double-rod cylinder has a 100 mm external stop screw window, allowing you to trim the extend stroke from the 300 mm maximum down to 200 mm. The stop screw sets end position but is not a load lock.
