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

About the Airtac SUJ Adjustable Cylinder SUJ100X50-50
The AirTAC SUJ100X50-50 is a double-acting double-rod profile cylinder with a 100mm bore, 1/2" port, and an external stop screw that lets you trim the extend stroke by up to 50mm on-site.
The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. This non-magnet SKU cannot take a switch. The SAUJ upgrade switches legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X50-50 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 SAUJ100X50-50 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

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 SUJ100X50-50 Is Used
Press Fit Tuning
Adjust the extend stroke on-site to dial in exact pressing distances for bearings without swapping cylinders.
Variable Stops
Trim the extend position to accommodate different product lengths on a packaging line.
Clamp Positioning
Fine-tune the clamping reach on the fly to handle varying workpiece thicknesses.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X50-50 with the SAUJ100X50-50
To replace the discontinued SUJ100X50-50, order the direct replacement SAUJ100X50-50, which matches the 100mm bore, 50mm stroke, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors, whereas this legacy model used CS1-B/DS1-B. Choose the 50mm adjust window when you need field tuning of the extend stroke. For strokes over 300mm, verify side-load limits. This non-magnet version cannot support sensing.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X50-50
- ✓ 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 SUJ100X50-50 FAQ
Yes, the SUJ100X50-50 is discontinued. The direct replacement is the SAUJ100X50-50, offering the same 100mm bore, 50mm stroke, 1/2" port, and FA/LB mounting.
The double-acting double-rod SUJ100X50-50 pushes 3927N and pulls 3681N at 0.5MPa, pushing 5497N at 0.7MPa and 7068N at 0.9MPa, with an 801kgf max. The external stop screw trims the extend stroke by up to 50mm on-site.
