This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X230-75S, 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 SUJ100X230-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X230-75S is a double-acting profile-type standard cylinder with a Ø100mm bore and 230mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X230-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X230-75S
The AirTAC SUJ100X230-75S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 155-230 mm extension from the 230 mm nominal maximum. This discontinued model is replaced direct by the SAUJ100X230-75S, which retains the exact bore, stroke, force, port, and FA/LB mounting.
The SAUJ upgrade transitions the -S magnet option from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. Remember the stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X230-75S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUJ100X230-75S 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). |
|---|---|
| 100 | Bore size in mm. |
| ×230 | 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 SUJ100X230-75S Is Used
Variable Depth Forming Press
Adjusts the extend stroke on-site by up to 75 mm to accommodate different material thicknesses without repositioning the entire fixture.
Variable Length Diverter
Tunes the pusher extension between 155 mm and 230 mm to handle changing package sizes on a packaging line.
Adjustable Height Pallet Stop
Trims the extend stroke to act as a hard stop for varying pallet heights, ensuring precise positioning before stretch wrapping.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X230-75S with the SAUJ100X230-75S
To replace the discontinued SUJ100X230-75S, order the direct replacement SAUJ100X230-75S, keeping the 100 mm bore, 230 mm nominal stroke, 75 mm adjust window, and 1/2 inch port. Select the 75 mm adjust window if your fixture needs field tuning between 155 mm and 230 mm; a fixed SAU plus external stop lacks this integrated trim. Mounting uses basic, FA, or LB brackets (AirTAC SC series compatible only). For the -S magnet, swap legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches. For stroke lengths of 300 mm or longer, verify side-load limits to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X230-75S
- ✓ 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 SUJ100X230-75S FAQ
Yes, the SUJ100X230-75S is discontinued. The direct replacement is the SAUJ100X230-75S, offering the same 100 mm bore, 230 mm stroke, 75 mm adjust window, 1/2 inch port, and FA/LB mounting. You only need to upgrade the -S magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The external stop screw provides a 75 mm adjust window, allowing you to shorten the 230 mm extend stroke down to 155 mm on-site. The stop sets end position only and is not a load lock.
