This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X200-100STC, 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 SUJ40X200-100STC
The AirTAC SUJ Adjustable Cylinder SUJ40X200-100STC is a double-acting profile-type standard cylinder with a Ø40mm bore and 200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X200-100STC, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X200-100STC
The AirTAC SUJ40X200-100STC is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 100-200 mm extension from the 200 mm nominal maximum. It features a 16 mm rod, M12x1.25 rod thread, 21 mm adjustable cushions, and a 1/4" port. This unit is DISCONTINUED; the direct replacement is the SAUJ40X200-100STC, retaining the same force, bore, stroke, and SC-series mounting interface.
The stop screw sets the end position but is not a load lock; drift occurs on air loss, requiring an external rod lock for held loads. Beyond the direct SAUJ upgrade, the SAUJ uses current CMSG/DMSG/EMSG sensors instead of this model's legacy CS1-B/DS1-B switches, and the compact profile barrel is shorter than standard ISO 15552 cylinders.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X200-100STC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAUJ40X200-100STC 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 SUJ40X200-100STC Is Used
Variable Pitch Indexing
Adjusts the extend stroke on-site to tune part ejection distance on the fly without swapping out the entire cylinder assembly.
Dynamic Reject Pusher
Trims the extend stroke to accommodate varying product widths on a packaging line, ensuring accurate rejection without repositioning sensors.
Adjustable Divert Gate
Sets precise gate travel for sorting mixed-size cartons, allowing operators to shorten the stroke up to 100 mm as bin configurations change.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X200-100STC with the SAUJ40X200-100STC
To replace the discontinued SUJ40X200-100STC, order the direct replacement SAUJ40X200-100STC, which matches the 40 mm bore, 200 mm nominal stroke, 100 mm adjust window, 1/4" port, and TC mounting interface. Choose the 100 mm adjust window when you need on-site extend trimming between 100 mm and 200 mm without adding an external stop. The TC mount utilises SC-series accessories. Because this configuration includes a magnet (-S), you must upgrade from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X200-100STC
- ✓ 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 SUJ40X200-100STC FAQ
Yes, the SUJ40X200-100STC is discontinued. The direct replacement is the SAUJ40X200-100STC, which matches the 40 mm bore, 200 mm nominal stroke, 100 mm adjust window, 1/4" port, and TC mounting interface. You will need to upgrade your position sensors from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG series.
The external stop screw provides a 100 mm adjust window, allowing you to shorten the 200 mm nominal extend stroke down to 100 mm on-site. The stop sets end position but is not a load lock.
