This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X200-30, 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 SUJ50X200-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X200-30 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 SAUJ50X200-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X200-30
The AirTAC SUJ50X200-30 is a double-acting double-rod adjustable-stroke profile cylinder, now discontinued. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable 170-200 mm extension out of the 200 mm nominal maximum. The extruded aluminum profile barrel is notably shorter than a standard cylinder of the same bore.
The direct replacement is the SAUJ50X200-30, matching the bore, stroke, force, port, and FA/LB mounting. 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, whereas the SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of legacy CS1-B/DS1-B.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X200-30 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 SAUJ50X200-30 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 SUJ50X200-30 Is Used
Variable Pitch Pushing
Tuning the extend stroke by up to 30 mm on-site to push parts of varying widths into a machining station without re-fitting the entire cylinder.
Adjustable Transfer Stops
Setting a precise 170 to 200 mm extend position to act as a dynamic flow barrier on a conveyor, allowing rapid format changes for different package sizes.
Variable Depth Ejection
Dialing in the extend stop to eject bins of varying depths from a storage rack, ensuring the rod never over-travels into the shelf frame.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X200-30 with the SAUJ50X200-30
To replace this discontinued SUJ50X200-30, specify the SAUJ50X200-30 direct. Choose the -30 adjust window to trim the 200 mm extend stroke by up to 30 mm on-site; the stop sets end position and is not a lock. Mounting is SC-series compatible via FA or LB brackets. Because this SKU lacks a magnet, it cannot take a switch; the SAUJ upgrade requires current CMSG/DMSG/EMSG sensors instead of legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X200-30
- ✓ 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 SUJ50X200-30 FAQ
Yes, the SUJ50X200-30 is discontinued. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw window is 30 mm, meaning you can shorten the 200 mm nominal extend stroke down to 170 mm on-site. The stop sets end position but is not a load lock.
