This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X200-10S, 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 SUJ50X200-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X200-10S 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 SAUJ50X200-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X200-10S
The AirTAC SUJ50X200-10S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 190-200 mm stroke. The nominal 200 mm is the maximum.
The direct replacement is the SAUJ50X200-10S, which preserves the bore, stroke, force, port, and FA/LB mounting. Upgrading to the SAUJ means switching 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 SAUJ50X200-10S 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 SAUJ50X200-10S 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 SUJ50X200-10S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×200 | 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 SUJ50X200-10S Is Used
Actuator End-Position Trimming
Dialing in the final 10 mm of a 200 mm extend stroke on a clamping fixture without remachining hard stops.
Transfer Pusher Adjustment
Fine-tuning a 50 mm bore push-off stroke on-site to accommodate varying product lengths on a packaging line.
Divert Gate Profiling
Setting a precise 190 mm extend stop for a sorting gate where the full 200 mm nominal travel is slightly excessive.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X200-10S with the SAUJ50X200-10S
To replace the discontinued SUJ50X200-10S, order the direct replacement SAUJ50X200-10S, keeping the 50 mm bore, 200 mm stroke, 10 mm adjust window, and FA/LB mounting. Select the 10 mm adjust window when you need minor on-site extend tuning. Because this unit has the -S magnet, you must upgrade your switches from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors. For this 200 mm stroke, verify side-load limits. The stop screw sets end position only; add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X200-10S
- ✓ 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 SUJ50X200-10S FAQ
Yes, the SUJ50X200-10S is discontinued. The direct replacement is the SAUJ50X200-10S, which matches the 50 mm bore, 200 mm stroke, 10 mm adjust window, 1/4" port, and FA/LB mounting. You must upgrade the -S magnet sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The external stop screw window is 10 mm, allowing you to shorten the extend stroke from the 200 mm maximum down to 190 mm on-site.
