This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X50-50S, 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 SUJ100X50-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X50-50S 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 SAUJ100X50-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X50-50S
The AirTAC SUJ100X50-50S is a double-acting double-rod profile cylinder with a 50 mm extend-stroke adjustment window, allowing you to trim the nominal 50 mm stroke down to zero on-site. It features a 1/2 inch port, a 25 mm rod, and 29 mm adjustable air cushions. This discontinued unit is replaced by the SAUJ100X50-50S.
The SAUJ direct keeps the bore, stroke, force, and FA/LB mounting identical, but upgrades position sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. The external 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 SAUJ100X50-50S 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 SAUJ100X50-50S 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 SUJ100X50-50S
| 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 SUJ100X50-50S Is Used
Press Fit Tuning
Allows operators to dial in the exact extend contact point for inserting bearings without machining hard stops.
Variable Diverter Gates
Adjusts the extend length on-site to route different package sizes on a packaging line.
Adjustable Product Pushers
Trims the extend stroke to push varying carton widths off an accumulation roller table.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X50-50S with the SAUJ100X50-50S
To replace the discontinued SUJ100X50-50S, specify the SAUJ100X50-50S for an direct match on bore, 50 mm stroke, 50 mm adjust window, 1/2 inch port, and FA/LB mounting. Choose the 50 mm adjust window when you need precise field tuning of the extend stroke. Because this is an -S model, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAUJ. For this 50 mm stroke, side-load is minimal, but always confirm guide alignment. The stop screw sets end position only; it does not hold loads on air loss.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X50-50S
- ✓ 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 SUJ100X50-50S FAQ
Yes, the SUJ100X50-50S is discontinued. The direct replacement is the SAUJ100X50-50S, which matches the 100 mm bore, 50 mm stroke, 50 mm adjust window, 1/2 inch port, and FA/LB mounting. The SAUJ also upgrades position sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The theoretical max is 801 kgf at 1.0 MPa. The external stop screw allows you to trim the 50 mm nominal extend stroke by up to 50 mm on-site. The stop sets end position only and is not a load lock.
