This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X200-50, 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 SUJ50X200-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X200-50 is a double-acting profile-type standard cylinder with a Ø50mm bore and 200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ50X200-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X200-50
The AirTAC SUJ50X200-50 is a double-acting double-rod profile cylinder with a 200mm maximum extend stroke and a 50mm external stop-screw window, allowing you to trim the extend stroke on-site to a usable 150-200mm. It features a 50mm bore, a 1/4" port, and adjustable 21mm cushions at each end. The 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.
The direct replacement is the SAUJ50X200-50, matching the bore, stroke, force, port, and FA/LB mounting. This SKU has no magnet and cannot take a switch, whereas upgrading to the SAUJ enables current CMSG/DMSG/EMSG sensors (the SUJ used legacy CS1-B/DS1-B). The compact profile barrel is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X200-50 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 SAUJ50X200-50 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 SUJ50X200-50 Is Used
Variable Stroke Clamping
Adjusts the extend end position on-site for clamping parts of varying heights without repositioning the entire fixture.
Variable Reject Diverter
Trims the extend stroke to push different product sizes off a belt, ensuring the diverting finger retracts cleanly.
Adjustable End Stop Pusher
Sets a precise 150-200mm extend stroke to push containers to an exact location without adding external mechanical stops.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X200-50 with the SAUJ50X200-50
To replace the discontinued SUJ50X200-50, order the SAUJ50X200-50 for an direct match in bore, force, 1/4" port, and FA/LB mounting. Choose the 50mm adjust window when you need to trim the extend stroke by up to 50mm on-site, setting a precise 150-200mm end position. Because this SKU lacks a magnet, it cannot take a switch; the SAUJ upgrade supports CMSG/DMSG/EMSG sensors (replacing legacy CS1-B/DS1-B). For strokes of 300mm or longer, verify side-load limits to prevent rod binding. The stop screw is not a load lock—install an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X200-50
- ✓ 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 SUJ50X200-50 FAQ
Yes, the SUJ50X200-50 is discontinued. The direct replacement is the SAUJ50X200-50, matching the 50mm bore, 200mm stroke, 1/4" port, and FA/LB mounting. The SAUJ also supports current CMSG/DMSG/EMSG sensors.
This double-acting double-rod cylinder pushes 982N @0.5MPa, 1374N @0.7MPa, and 1767N @0.9MPa; pull is 825N @0.5MPa. The 50mm stop-screw window trims the extend stroke on-site from 200mm down to 150mm. The stop sets end position but is not a load lock.
