This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ63X200-20S, 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 SUJ63X200-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X200-20S 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 SAUJ63X200-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X200-20S
The AirTAC SUJ63X200-20S is a double-acting double-rod profile cylinder with a 63mm bore and 200mm nominal stroke, featuring an external stop screw that lets you trim the extend stroke by up to 20mm on-site (yielding a usable 180-200mm window). The stop sets the end position but is not a load lock; use an external rod lock for held loads.
Because the SUJ line is end-of-life, the direct replacement is the SAUJ63X200-20S, matching the bore, stroke, force, port, and FA/LB mounting. A key upgrade is position sensing: this legacy unit uses CS1-B/DS1-B switches, while the SAUJ uses current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X200-20S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAUJ63X200-20S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 63 | 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 SUJ63X200-20S Is Used
Variable Pitch Indexing
Dialing in the exact extend stop on-site allows a clamping unit to accommodate multiple part lengths without swapping entire actuators.
Sorting Diverter Setup
Field-trimming the extend stroke by up to 20mm lets operators fine-tune the pusher distance to match varying package widths on the fly.
Adjustable End Stops
Perfect for shelving actuators where the final extend position must be tweaked after installation to clear obstructions or meet tolerances.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X200-20S with the SAUJ63X200-20S
To replace the discontinued SUJ63X200-20S, order the direct replacement SAUJ63X200-20S, which retains the 63mm bore, 200mm nominal stroke, 3/8 inch port, and FA/LB mounting. Select the -20mm adjust window if your mechanism needs field tuning of the extend stroke from 180 to 200mm; for fixed stops, a standard SAU cylinder suffices. Because this is an -S model, note the sensor change from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG. For strokes of 300mm or longer, verify side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X200-20S
- ✓ 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 SUJ63X200-20S FAQ
Yes, the SUJ63X200-20S is discontinued. The direct replacement is the SAUJ63X200-20S, offering the same 63mm bore, 200mm stroke, 3/8 inch port, and FA/LB mounting. You will need to upgrade your position sensors from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG series.
The external stop screw offers a 20mm adjust window, allowing you to shorten the 200mm extend stroke down to 180mm on-site. Note the stop sets end position and is not a load lock.
