This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X100-100S, 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 SUJ50X100-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X100-100S is a double-acting profile-type standard cylinder with a Ø50mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ50X100-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X100-100S
The AirTAC SUJ50X100-100S is a double-acting double-rod profile cylinder with a 100mm adjustable stroke window. An external stop screw lets you trim the extend stroke by up to 100mm on-site, dropping the usable extension from the 100mm maximum down to zero. This unit is discontinued; the direct replacement is the SAUJ50X100-100S, retaining the 1/4" port, M16x1.5 rod thread, and FA/LB mounting.
The stop screw sets the end position but is not a load lock; cylinders drift on air loss, so use an external rod lock for held loads. Beyond the legacy CS1-B/DS1-B sensor shift to CMSG/DMSG/EMSG on the SAUJ, choosing this adjustable cylinder over a fixed SAU plus external stop saves space and simplifies mounting.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X100-100S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAUJ50X100-100S 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 SUJ50X100-100S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | 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 SUJ50X100-100S Is Used
Variable Depth Gauging
Probes parts where the extend stroke requires precise on-site tuning up to 100mm to hit different inspection depths without swapping cylinders.
Adjustable Forming Press
Handles multiple material thicknesses on one fixture by dialing the extend stroke down from the 100mm maximum to the exact contact point.
Dynamic Packaging Flap
Closes cartons of varying heights by trimming the extend stroke on-site, ensuring consistent pressure without reprogramming the machine.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X100-100S with the SAUJ50X100-100S
To replace the discontinued SUJ50X100-100S, specify the SAUJ50X100-100S direct: it matches the 50mm bore, 100mm stroke, 100mm adjust window, 1/4" port, and FA/LB mounts. The 100mm adjust window is ideal when exact end positions vary per job. Because this model includes the -S magnet, upgrade from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For strokes of 300mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X100-100S
- ✓ 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 SUJ50X100-100S FAQ
Yes, the SUJ50X100-100S is discontinued. The direct replacement is the SAUJ50X100-100S, which matches the 50mm bore, 100mm stroke, 100mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw allows you to trim the extend stroke by up to 100mm on-site, reducing the usable extension from the 100mm maximum down to zero.
