This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X200-75S, 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 SUJ50X200-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X200-75S 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 SAUJ50X200-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X200-75S
The AirTAC SUJ50X200-75S is a double-acting, double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 125-200 mm extension from the 200 mm nominal maximum. It features a 1/4" port, a 20 mm rod, and adjustable 21 mm cushions.
This unit is discontinued and drops in directly with the SAUJ50X200-75S, which retains the exact bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade shifts 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 SAUJ50X200-75S 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 SAUJ50X200-75S 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 SUJ50X200-75S Is Used
Variable Pitch Pushing
Feeding different length blanks on a single line by dialing the extend stroke down 75 mm on-site without swapping cylinders.
Adjustable Diverter Gate
Tuning a sorting gate arm between 125 mm and 200 mm to handle changing package sizes on the fly.
Custom Stack Height Stop
Setting precise mechanical end positions for stacking varied pallet loads where a fixed stroke lacks flexibility.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X200-75S with the SAUJ50X200-75S
To replace the discontinued SUJ50X200-75S, order the direct replacement SAUJ50X200-75S, matching the 50 mm bore, 200 mm max stroke, 75 mm adjust window, and 1/4" port. If migrating sensors, note the SAUJ uses CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. The 75 mm adjust window is ideal when final extend position is unknown at build time, beating a fixed SAU plus external stop. Retain FA or LB mounting from the SC series. For strokes of 300 mm or longer, verify side-load guidance to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X200-75S
- ✓ 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 SUJ50X200-75S FAQ
Yes, the SUJ50X200-75S is discontinued. The direct replacement is the SAUJ50X200-75S, offering the same 50 mm bore, 200 mm max stroke, 75 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw allows you to trim the extend stroke by up to 75 mm on-site, giving a usable extension range of 125-200 mm. The stop sets end position and is not a load lock.
