This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ63X200-50, 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 SUJ63X200-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X200-50 is a double-acting profile-type standard cylinder with a Ø63mm bore and 200mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ63X200-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X200-50
The AirTAC SUJ63X200-50 is a discontinued double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site. With a nominal 200 mm stroke, the usable extend range is 150-200 mm. The stop sets the end position; it is not a load lock. It features a 3/8" port, a 20 mm rod, and 21 mm adjustable cushions.
The direct replacement is the SAUJ63X200-50, matching the bore, stroke, force, port, and FA/LB mounting. Upgrading to the SAUJ moves you to current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here. This SKU has no magnet and cannot take a switch.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAUJ63X200-50 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 SUJ63X200-50 Is Used
Variable Depth Boring
Machine tools needing field stroke tuning to set precise boring depths between 150 mm and 200 mm without swapping the entire cylinder.
Adjustable Carton Flaps
Packaging lines handling varied carton heights use the 50 mm adjust screw to alter the extend endpoint on-site for different box formats.
Tunable Diverter Gate
Conveyor sorting systems where the diverter gate reach requires on-site stroke trimming to accommodate product width changes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X200-50 with the SAUJ63X200-50
To replace this discontinued unit, order the SAUJ63X200-50. It is a direct: same 63 mm bore, 200 mm stroke, 50 mm adjust window, 3/8" port, and FA/LB mounts. Choose the 50 mm adjust window if you need to tune the extend stroke down to 150 mm on-site; this is often preferred over a fixed SAU plus an external stop because it saves space and simplifies mounting. This non-magnetic SKU cannot take a switch; the SAUJ -S variant uses CMSG/DMSG/EMSG sensors. For this 200 mm stroke, check side-load guides. For load holding, add an external rod lock, as the stop screw and cushions do not lock the piston.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X200-50
- ✓ 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 SUJ63X200-50 FAQ
Yes, the SUJ63X200-50 is discontinued. The direct replacement is the SAUJ63X200-50. It matches the 63 mm bore, 200 mm stroke, 50 mm adjust window, 3/8" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The theoretical max is 318 kgf at 1.0 MPa. The external stop screw offers a 50 mm adjust window, meaning the 200 mm extend stroke can be shortened to 150 mm on-site. The stop sets end position and is not a load lock.
