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

About the Airtac SUJ Adjustable Cylinder SUJ63X200-20
The AirTAC SUJ63X200-20 is a discontinued double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 180-200 mm stroke. The nominal 200 mm represents the maximum extension. It features a 63 mm bore, a 20 mm piston rod, M16x1.5 rod-end thread, adjustable 21 mm air cushions at each end, and a 3/8" port. Because this SKU lacks a magnet, it cannot accept a magnetic switch for position sensing.
The direct replacement is the SAUJ63X200-20, matching the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors over the legacy CS1-B/DS1-B switches used here, and the stop screw sets end position but is not a load lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X200-20 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 SAUJ63X200-20 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 SUJ63X200-20 Is Used
Custom Clamping Stops
Adjusting the extend stroke on-site by up to 20 mm allows operators to tune clamping positions for varying part widths without swapping cylinders.
Variable Length Diverters
Trimming the extend stroke from the 200 mm maximum lets a diverter arm accommodate different package sizes on a single conveyor line.
Adjustable Pusher Travel
Fine-tuning the extend end position in the field ensures precise product pushing distances when handling mixed carton lengths.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X200-20 with the SAUJ63X200-20
To replace the discontinued SUJ63X200-20, specify the direct replacement SAUJ63X200-20, which preserves the 63 mm bore, 200 mm stroke, 3/8" port, and FA/LB mounting. The 20 mm adjust window is ideal if your extend stroke needs field tuning between 180 mm and 200 mm, often beating a fixed SAU plus an external stop. If you previously relied on legacy CS1-B/DS1-B sensors, note that the SAUJ uses current CMSG/DMSG/EMSG switches, though this specific non-magnet SKU cannot accept them anyway. For strokes of 300 mm or longer, verify your side-load limits to prevent excessive guide wear. Remember that the stop screw only sets the end position; it is not a lock, so use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X200-20
- ✓ 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 SUJ63X200-20 FAQ
Yes, the SUJ63X200-20 is discontinued. The SAUJ also supports current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw provides a 20 mm adjust window, allowing you to shorten the 200 mm maximum extend stroke down to 180 mm on-site. The stop sets end position but is not a load lock.
