This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X160-40, 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 SUJ40X160-40
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X160-40 is a double-acting profile-type standard cylinder with a Ø40mm bore and 160mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X160-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X160-40
The AirTAC SUJ40X160-40 is a double-acting double-rod profile cylinder with a 160 mm nominal stroke and a 40 mm external stop screw window, letting you trim the extend stroke on-site down to 120 mm. The extruded aluminum profile barrel is noticeably shorter than an ISO 15552 unit of the same bore. This SUJ model is discontinued; the direct replacement is the SAUJ40X160-40, matching the 1/4" port, M12x1.25 rod thread, and 21 mm cushions.
The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. Because this SKU lacks a magnet, it cannot take a magnetic switch. Upgrading to the SAUJ also brings current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used here.

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 SAUJ40X160-40 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 SUJ40X160-40 Is Used
Variable Depth Drilling
Trimming the extend stroke by up to 40 mm on-site allows precise depth control for drilling operations without swapping the entire cylinder.
Adjustable Push-off Diverter
Field-tuning the extend stroke lets operators change the push distance for varying box sizes directly on the conveyor line.
Custom Length Packaging Flap
Dialing in the stroke end position accommodates different carton depths on the fly for packaging flap folding.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X160-40 with the SAUJ40X160-40
To replace the discontinued SUJ40X160-40, order the direct replacement SAUJ40X160-40, which retains the 40 mm bore, 160 mm stroke, 1/4" port, and FA/LB mounting. Choose the 40 mm adjust window if you need to trim the extend stroke by up to 40 mm on-site; this stop sets end position and is not a lock. For stroke lengths of 300 mm or more, verify your side-load limits. Note this non-magnetic SKU cannot take sensors, whereas the SAUJ uses CMSG/DMSG/EMSG switches.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X160-40
- ✓ 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 SUJ40X160-40 FAQ
Yes, the SUJ40X160-40 is discontinued. The direct replacement is the SAUJ40X160-40, which matches the 40 mm bore, 160 mm stroke, 40 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 switches.
The external stop screw window is 40 mm, allowing you to shorten the 160 mm extend stroke down to 120 mm on-site. The stop sets end position and is not a load lock.
