This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X100-40S, 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 SUJ40X100-40S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X100-40S 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 SAUJ40X100-40S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X100-40S
The AirTAC SUJ40X100-40S is a discontinued double-acting double-rod profile cylinder with a 40 mm bore and 100 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, giving a usable 60-100 mm window. The direct replacement is the SAUJ40X100-40S, sharing the exact bore, stroke, force, and mounting.
The SAUJ upgrade switches legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. Remember the stop screw sets end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X100-40S 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 SAUJ40X100-40S 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 SUJ40X100-40S Is Used
Variable Depth Drilling
Adjust the extend stroke by up to 40 mm on-site to change drill depth without swapping cylinders.
Variable Length Diverter
Tune the extend stroke from 60 to 100 mm to deflect different package sizes accurately.
Adjustable Forming Press
Trim the extend end position by up to 40 mm to accommodate varying carton forming heights.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X100-40S with the SAUJ40X100-40S
To replace this discontinued unit, order the SAUJ40X100-40S, which matches the 40 mm bore, 100 mm nominal stroke, 40 mm adjust window, 1/4" port, and FA/LB mounting. Choose the 40 mm adjust window if you need on-site extend tuning between 60 and 100 mm. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B. For this 100 mm stroke, side-load is minimal, but always guide the rod for longer strokes. The stop screw sets end position and does not hold loads without live air.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X100-40S
- ✓ 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
