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

About the Airtac SUJ Adjustable Cylinder SUJ63X200-50STC
The AirTAC SUJ63X200-50STC is a double-acting, double-rod profile cylinder with an adjustable extend stroke. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 150-200 mm stroke from the 200 mm nominal maximum. It features a 3/8" port, an M16x1.5 rod thread, and 21 mm adjustable air cushions.
This SUJ series is discontinued. The direct replacement is the SAUJ63X200-50STC, retaining the same bore, stroke, force, 3/8" port, and TC mounting interface. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S magnet model. Note that the stop screw sets the end position but is not a load lock; an external rod lock is required to hold loads on air loss.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X200-50STC 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 SAUJ63X200-50STC 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 SUJ63X200-50STC Is Used
Reject Diverter Calibration
Trimming the extend stroke by up to 50 mm on-site allows precise tuning of a reject arm on a conveyor without machining custom spacers.
Variable Carton Sealing
Adjusting the extend endpoint on the fly accommodates fluctuating carton sizes, ensuring exact contact pressure for sealing heads.
End-of-Arm Tooling Setup
Dialing in the 150-200 mm usable stroke window at the machine simplifies final positioning of clamps and grippers during changeovers.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X200-50STC with the SAUJ63X200-50STC
To replace the discontinued SUJ63X200-50STC, order the direct replacement SAUJ63X200-50STC, which matches the 63 mm bore, 200 mm stroke, 50 mm adjust window, 3/8" port, and TC mount. Choose the 50 mm adjust window when you need on-site stroke tuning between 150 mm and 200 mm. The SAUJ accepts current CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches. For strokes of 300 mm or longer, verify side-load limits. Because the stop screw only sets end position, specify an external rod lock for suspended loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X200-50STC
- ✓ 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 SUJ63X200-50STC FAQ
Yes, the SUJ63X200-50STC is discontinued. The direct replacement is the SAUJ63X200-50STC, offering the same 63 mm bore, 200 mm stroke, 50 mm adjust window, 3/8" port, and TC mounting. You will need to upgrade the position sensors from the legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG switches.
The external stop screw allows you to trim the extend stroke by up to 50 mm on-site, giving a usable stroke of 150-200 mm. The screw sets the end position and is not a load lock.
