This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X50-30S, 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 SUJ100X50-30S
The AirTAC SUJ Adjustable Cylinder SUJ100X50-30S is a double-acting profile-type standard cylinder with a Ø100mm bore and 50mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X50-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X50-30S
The AirTAC SUJ100X50-30S is a double-acting double-rod profile cylinder with a 100mm bore and 50mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 30mm on-site, yielding a usable 20-50mm stroke window. The 1/2" port and 29mm adjustable cushions handle high flow and energy dissipation. This discontinued model used a CS1-B/DS1-B piston magnet for position sensing.
The SUJ100X50-30S is discontinued; the direct replacement is the SAUJ100X50-30S, retaining the same bore, stroke, force, 1/2" port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors and offers the SAUF built-in-valve variant. The external stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X50-30S 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 SAUJ100X50-30S 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. |
| ×50 | 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 SUJ100X50-30S Is Used
Adjustable Pressing Stops
Trimming the extend stroke by up to 30mm on-site allows precise positioning of pressing tools without machining custom spacers.
Variable Length Diverters
Field-tuning the 20-50mm stroke window adapts diverter gates on packaging lines to different carton sizes quickly.
Custom Ejector Pins
Dialing in the exact extend stop ensures delicate product ejection at varying distances without reprogramming the machine.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X50-30S with the SAUJ100X50-30S
To replace the discontinued SUJ100X50-30S, order the direct replacement SAUJ100X50-30S, which matches the 100mm bore, 50mm stroke, 30mm adjust window, 1/2" port, and FA/LB mounting. The -S suffix means a magnet is present; note that your legacy CS1-B/DS1-B switches must change to current CMSG/DMSG/EMSG sensors on the SAUJ. Choose the 30mm adjust window when you need field-tuning of the extend stroke between 20mm and 50mm. The stop screw sets end position but is not a lock; for held loads, add an external rod lock. For strokes of 300mm or longer, verify side-load guidance to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X50-30S
- ✓ 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 SUJ100X50-30S FAQ
Yes, the SUJ100X50-30S is discontinued. The direct replacement is the SAUJ100X50-30S. It matches the 100mm bore, 50mm nominal stroke, 30mm adjust window, 1/2" port, and FA/LB mounting. You must upgrade your position sensors from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG switches.
The external stop screw allows you to trim the extend stroke by up to 30mm on-site, creating a usable 20-50mm stroke window. The stop sets end position but is not a load lock.
