This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X100-40, 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 SUJ40X100-40
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X100-40 is a double-acting profile-type standard cylinder with a Ø40mm bore and 100mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X100-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X100-40
The AirTAC SUJ40X100-40 is a discontinued double-acting double-rod adjustable-stroke profile cylinder. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 60 to 100 mm extend window from the 100 mm nominal maximum. The direct replacement is the SAUJ40X100-40, matching the bore, stroke, force, port, and FA/LB mounting.
This SKU lacks a magnet and cannot take a magnetic switch. The SAUJ upgrade switches to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

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 SUJ40X100-40 Is Used
Variable Depth Drilling
Trimming the extend stroke by up to 40 mm on-site allows a fixture to adapt drilling depth for different material thicknesses without swapping cylinders.
Adjustable Pusher Stroke
Tuning the extend window down from 100 mm to 60 mm lets a transfer line push varying package sizes accurately to a stop.
Variable Height Diverter
Field-adjusting the extend end position enables a diverter gate to redirect items of differing heights on the fly.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X100-40 with the SAUJ40X100-40
To replace the discontinued SUJ40X100-40, order the SAUJ40X100-40 direct. Choose the 40 mm adjust window if you need to trim the extend stroke by up to 40 mm on-site. Mounting is Basic, FA, or LB. Because this SKU has no magnet, it cannot accept sensors; the SAUJ uses CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits. The stop screw sets end position only; add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X100-40
- ✓ 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 SUJ40X100-40 FAQ
Yes, the SUJ40X100-40 is discontinued. The direct replacement is the SAUJ40X100-40, which matches the 40 mm bore, 100 mm stroke, 40 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw provides a 40 mm adjust window, shortening the 100 mm nominal extend stroke down to 60 mm. The stop sets end position and is not a load lock.
