This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X200-75S, 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 SUJ40X200-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X200-75S 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 SAUJ40X200-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X200-75S
The AirTAC SUJ40X200-75S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 125-200 mm extension from the 200 mm nominal maximum. This discontinued unit is fully replaced by the direct replacement SAUJ40X200-75S.
The SAUJ successor keeps the SC-series FA/LB mounting but upgrades sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. Remember the stop screw sets end position; it is not a load lock, so add an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X200-75S 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 SAUJ40X200-75S 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 SUJ40X200-75S Is Used
Variable Depth Drilling
Trimming the 200 mm extend stroke by up to 75 mm on-site allows precise depth control for drilling operations without swapping cylinders.
Adjustable Carton Sealing
Field-tuning the extend stroke accommodates varying box heights on a packaging line, ensuring consistent flap closure.
Dynamic Reject Pushing
The 75 mm adjust window lets operators reposition the reject arm in seconds to handle different product lengths on the conveyor.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X200-75S with the SAUJ40X200-75S
To replace this discontinued SUJ40X200-75S, specify the exact direct replacement SAUJ40X200-75S, which matches the 40 mm bore, 200 mm stroke, 75 mm adjust window, 1/4" port, and FA/LB mounting. The 75 mm adjust window is ideal for field tuning without machining. Because this is an -S model, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAUJ. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X200-75S
- ✓ 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 SUJ40X200-75S FAQ
Yes, the SUJ40X200-75S is discontinued. The direct replacement is the SAUJ40X200-75S, which matches the 40 mm bore, 200 mm stroke, 75 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw provides a 75 mm adjust window, allowing the extend stroke to be shortened from 200 mm down to 125 mm on-site.
