This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X100-50S, 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 SUJ50X100-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X100-50S 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 SAUJ50X100-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X100-50S
The AirTAC SUJ50X100-50S is a double-acting double-rod profile cylinder with a 50 mm bore and 1/4" port, engineered for on-site stroke adjustment. An external stop screw lets you trim the extend stroke by up to 50 mm, yielding a usable 50-100 mm stroke from the 100 mm nominal maximum.
This SUJ50X100-50S is discontinued; the direct replacement is the SAUJ50X100-50S, matching the bore, stroke, force, port, and FA/LB mounting. The upgrade path moves from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X100-50S 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 SAUJ50X100-50S 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). |
|---|---|
| 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 SUJ50X100-50S Is Used
Variable Depth Drilling
Adjusting the extend stroke by up to 50 mm on-site allows precise depth control for multi-product drilling fixtures without swapping the entire cylinder.
Variable Length Sorting Diverter
Trimming the extend stroke dynamically accommodates different package sizes on a sorting line, ensuring the diverter meets exact product lengths.
Adjustable Height Lift Stop
Setting the external stop screw provides a hard mechanical end position for tiered shelving heights, allowing rapid reconfiguration of lift stations.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X100-50S with the SAUJ50X100-50S
To replace the discontinued SUJ50X100-50S, specify the SAUJ50X100-50S, which retains the 1/4" port, M16x1.5 rod thread, and 21 mm cushions. Choose the 50 mm adjust window when you need to trim the extend stroke by up to 50 mm on-site—useful when a fixed SAU plus external stop is too bulky. The -S magnet means upgrading from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X100-50S
- ✓ 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 SUJ50X100-50S FAQ
Yes, the SUJ50X100-50S is discontinued. The direct replacement is the SAUJ50X100-50S, which matches the 50 mm bore, 100 mm stroke, 50 mm adjust window, and 1/4" port. You will simply upgrade the legacy CS1-B/DS1-B sensors to the current CMSG/DMSG/EMSG switches.
The external stop screw allows you to trim the extend stroke by up to 50 mm on-site, giving a usable stroke range of 50-100 mm. The stop sets end position but is not a load lock.
