This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ63X200-30S, 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 SUJ63X200-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X200-30S 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 SAUJ63X200-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X200-30S
The AirTAC SUJ63X200-30S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 170-200 mm extend out of the 200 mm nominal maximum. It features a 20 mm rod, M16x1.5 rod thread, and a 3/8" port.
This SUJ model is discontinued; the direct replacement is the SAUJ63X200-30S, matching the bore, stroke, force, port, and FA/LB mounting. The upgrade path moves 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 SAUJ63X200-30S 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 SAUJ63X200-30S 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 SUJ63X200-30S Is Used
Variable Pitch Indexing
Adjusts the extend stroke on-site to tune part ejection distance without swapping the entire cylinder.
Dynamic Diverter Gates
Trims the extend position to handle varying package sizes on a single conveyor line.
Carton Forming Stops
Sets precise end positions for different carton depths, allowing quick changeovers.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X200-30S with the SAUJ63X200-30S
To replace the discontinued SUJ63X200-30S, order the direct replacement SAUJ63X200-30S, keeping the 200 mm nominal stroke and 30 mm adjust window. Choose the 30 mm adjust window when you need precise 170-200 mm extend tuning. Retain FA or LB mounting from the SC series. Because this is an -S model, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X200-30S
- ✓ 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
