This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X275-100S, 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 SUJ100X275-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X275-100S is a double-acting profile-type standard cylinder with a Ø100mm bore and 275mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X275-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X275-100S
The AirTAC SUJ100X275-100S is a double-acting double-rod profile cylinder with a 100mm bore, 275mm nominal stroke, and a built-in piston magnet. An external stop screw allows you to trim the extend stroke by up to 100mm on-site, yielding a usable extend range of 175-275mm. The 1/2" port and 29mm adjustable cushions manage the 30-800mm/s speed range.
This SUJ model is discontinued and the direct replacement is the SAUJ100X275-100S, retaining the same force, 1/2" port, and FA/LB mounting. The SAUJ upgrade shifts legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. 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 SAUJ100X275-100S 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 SAUJ100X275-100S 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 SUJ100X275-100S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×275 | 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 SUJ100X275-100S Is Used
Adjustable Length Diverter
Route varying package sizes on a line by dialing the extend stroke in 1mm increments up to 100mm, avoiding the need to swap the entire cylinder for different box lengths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X275-100S with the SAUJ100X275-100S
To replace the discontinued SUJ100X275-100S, order the direct replacement SAUJ100X275-100S, keeping the 100mm bore, 275mm nominal stroke, and 100mm adjust window. Choose the -100mm adjust window when you need on-site extend trimming from 275mm down to 175mm without changing mounts. Retain FA or LB mounting brackets and note the -S magnet sensor change from CS1-B/DS1-B to CMSG/DMSG/EMSG. The external stop sets end position but is not a lock; add an external rod lock for held loads. For this 275mm stroke, verify side-load alignment to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X275-100S
- ✓ 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 SUJ100X275-100S FAQ
Yes, the SUJ100X275-100S is discontinued. The direct replacement is the SAUJ100X275-100S, which matches the 100mm bore, 275mm stroke, 100mm adjust window, 1/2" port, and FA/LB mounting. You must upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The external stop screw trims the extend stroke by up to 100mm on-site, giving a usable 175-275mm range. The stop sets end position only and is not a load lock.
