This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ63X200-50S, 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 SUJ63X200-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X200-50S 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 SAUJ63X200-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X200-50S
The AirTAC SUJ63X200-50S is a 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, yielding a usable 150-200 mm extend window from the 200 mm nominal maximum.
The direct replacement is the SAUJ63X200-50S, matching the 63 mm bore, stroke, force, and FA/LB mounting. Note the stop screw sets end position but is not a load lock; drift occurs on air loss without an external rod lock. The SAUJ upgrade also moves from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.

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 SAUJ63X200-50S 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 SUJ63X200-50S Is Used
Variable Pitch Forming
Bending or pressing operations where the extend stop must be dialed in precisely between 150 and 200 mm to accommodate different material thicknesses without reprogramming the motion controller.
Adjustable Transfer Diverter
Routing packages of varying sizes on a line by tuning the extend stroke on-site to hit the exact divert distance required for each product family.
Variable Depth Carton Sealing
Applying tape or labels to cartons of different depths by using the external stop screw to shorten the extend stroke, ensuring consistent contact pressure without changing the cylinder body.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X200-50S with the SAUJ63X200-50S
To replace the discontinued SUJ63X200-50S, specify the SAUJ63X200-50S for identical 63 mm bore, 200 mm stroke, 50 mm adjust window, 3/8" port, and FA/LB mounting. Select the 50 mm adjust window when you need on-site extend tuning between 150 and 200 mm. Because this is an -S model, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAUJ. For strokes of 300 mm or longer, verify side-load constraints to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X200-50S
- ✓ 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 SUJ63X200-50S FAQ
Yes, the SUJ63X200-50S is discontinued. The direct replacement is the SAUJ63X200-50S, which shares the same 63 mm bore, 200 mm nominal stroke, 50 mm adjust window, 3/8" port, and FA/LB mounting. You will need to upgrade the piston magnet sensors from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG series.
Push force rises to 2182 N at 0.7 MPa and 2805 N at 0.9 MPa, with a theoretical max of 318 kgf at 1.0 MPa. The external stop screw provides a 50 mm adjust window, allowing you to shorten the extend stroke from the 200 mm maximum down to 150 mm on-site. The stop sets the end position but does not lock the load.
