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

About the Airtac SUJ Adjustable Cylinder SUJ40X200-75
The AirTAC SUJ40X200-75 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 75 mm on-site, giving a usable stroke range of 125-200 mm from the 200 mm nominal maximum. The direct replacement is the SAUJ40X200-75, matching the bore, stroke, force, and SC-series FA/LB mounting.
The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. The SAUJ upgrade accepts current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches. Without a -S suffix, this specific SKU has no magnet and cannot accept a sensor.

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 SAUJ40X200-75 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 SUJ40X200-75 Is Used
Variable Depth Drilling
Trimming the extend stroke by up to 75 mm on-site allows a fixture to adapt drilling depth for multiple material thicknesses without swapping cylinders.
Adjustable Diverter Arms
Field-tuning the extend end position lets a diverter accommodate changing package sizes on a packaging line, ensuring precise routing.
Variable Height Stops
An external stop screw provides a hard mechanical end position for varying pallet heights, preventing over-travel in vertical positioning tasks.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X200-75 with the SAUJ40X200-75
To replace the discontinued SUJ40X200-75, order the SAUJ40X200-75 direct, which retains the 1/4" port, 200 mm nominal stroke, and 75 mm adjust window. The SAUJ keeps the FA and LB mounting options of the AirTAC SC series. Because this SKU lacks the -S suffix, it has no magnet; the SAUJ upgrade uses CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify your side-load limits to prevent guide wear. Remember the external stop sets end position and is not a lock.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X200-75
- ✓ 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
