This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X500-40, 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 SUJ100X500-40
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X500-40 is a double-acting profile-type standard cylinder with a Ø100mm bore and 500mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X500-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X500-40
The AirTAC SUJ100X500-40 is a double-acting double-rod profile cylinder with a 500 mm maximum extend stroke that an external stop screw can trim on-site by up to 40 mm, yielding a usable 460-500 mm stroke. Because the stop screw merely sets the end position, it is not a load lock; fit an external rod lock or pilot-operated check valve for held loads.
This SUJ unit is discontinued; the direct replacement is the SAUJ100X500-40, retaining the same 100 mm bore, 500 mm stroke, 40 mm adjust window, force, port, and FA/LB mounting. The SAUJ upgrade shifts sensing to current CMSG/DMSG/EMSG switches (this legacy SKU lacks a magnet and cannot take a switch) and offers the SAUF built-in-valve variant.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X500-40 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUJ100X500-40 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 SUJ100X500-40 Is Used
Press Fit Tuning
Adjusting the extend end position on-site by up to 40 mm allows operators to dial in the exact insertion depth for press-fit operations without swapping cylinders.
Variable Length Diverter
Trimming the 500 mm stroke lets a diverter gate accommodate changing package sizes on a conveyor line, ensuring packages push cleanly to the correct lane.
Adjustable End Stop
Setting a custom extend position between 460 and 500 mm provides a repeatable mechanical end stop for stacking or positioning pallets of varying heights.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X500-40 with the SAUJ100X500-40
To replace the discontinued SUJ100X500-40, order the SAUJ100X500-40; it is a direct for the 100 mm bore, 500 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounts. Choose the 40 mm adjust window when you need precise field tuning of the extend end position; note the stop screw sets position but does not lock the load. Because this SKU has no magnet, you cannot mount a switch; the SAUJ requires CMSG/DMSG/EMSG sensors. Finally, at 500 mm stroke, support the rod against side-load and bending with external guides.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X500-40
- ✓ 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 SUJ100X500-40 FAQ
Yes, the SUJ100X500-40 is discontinued. The direct replacement is the SAUJ100X500-40, which matches the 100 mm bore, 500 mm stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors, whereas this legacy SUJ lacks a magnet and cannot take a switch.
The external stop screw provides a 40 mm adjust window, shortening the 500 mm extend stroke to a minimum of 460 mm on-site. The screw sets end position and is not a load lock.
