This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X500-75S, 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 SUJ100X500-75S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X500-75S 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 SAUJ100X500-75S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X500-75S
The AirTAC SUJ100X500-75S is a double-acting double-rod profile cylinder with an adjustable stroke, featuring a 100mm bore and a 500mm maximum extend stroke. An external stop screw allows you to trim the extend stroke by up to 75mm on-site, yielding a usable extension range of 425-500mm. The 1/2" port and M20x1.5 rod thread handle high flow, while the 29mm adjustable cushions manage end-of-stroke deceleration. This unit is discontinued; the direct replacement is the SAUJ100X500-75S.
The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. The SAUJ upgrade retains the compact profile body and FA/LB mounts but switches sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. Because this unit has a 500mm stroke, external guides are recommended to prevent rod bending under side loads.

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 SAUJ100X500-75S 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 SUJ100X500-75S Is Used
Variable Depth Pressing
Allows operators to dial in the exact extension depth from 425 to 500mm on-site without swapping cylinders, perfect for pressing parts of varying heights.
Adjustable Transfer Stops
Provides a field-tunable end-stop for diverter arms on packaging lines, letting technicians shorten the extend stroke by up to 75mm to accommodate different package sizes.
Custom Height Lifting
Offers precise control over lift platform travel limits in material handling setups, enabling quick on-site adjustments to the maximum 500mm extension.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X500-75S with the SAUJ100X500-75S
To replace this discontinued SUJ100X500-75S, use the SAUJ100X500-75S, which matches the 100mm bore, 500mm nominal stroke, 75mm adjust window, 1/2" port, and FA/LB mounting. Choose the 75mm adjust window if you need to trim the extend stroke on-site from 425 to 500mm. Because this model includes the -S magnet, you must upgrade your position sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. For this 500mm stroke, ensure external guides are used to support the rod and mitigate side-load bending.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X500-75S
- ✓ 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 SUJ100X500-75S FAQ
Yes, the SUJ100X500-75S is discontinued. The direct replacement is the SAUJ100X500-75S, which shares the same 100mm bore, 500mm stroke, 75mm adjust window, 1/2" port, and FA/LB mounting. You will need to upgrade your sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The external stop screw allows you to trim the extend stroke by up to 75mm on-site, giving a usable range of 425-500mm. The stop sets end position and is not a load lock.
