This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X150-75, 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 SUJ100X150-75
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X150-75 is a double-acting profile-type standard cylinder with a Ø100mm bore and 150mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X150-75, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X150-75
The AirTAC SUJ100X150-75 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 75-150 mm stroke. The nominal 150 mm stroke is the maximum. It features a 100 mm bore, a 25 mm rod, M20x1.5 rod threads, adjustable 29 mm cushions, and a 1/2" port.
The direct replacement is the SAUJ100X150-75, matching the bore, stroke, force, and SC-series FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this SUJ used legacy CS1-B/DS1-B switches. As a plain non-magnetic SKU, it cannot take a sensor. The stop screw sets the 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 SAUJ100X150-75 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 SAUJ100X150-75 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 SUJ100X150-75 Is Used
Variable Stroke Pressing
Field-tune the extend stroke from 150 mm down to 75 mm to accommodate varying material thicknesses in a pressing station without swapping the cylinder.
Adjustable Diverter Arm
Set the exact reach of a diverter on a conveyor line by trimming the extend stroke on-site to match different package widths.
Custom End-Position Stops
Use the external stop screw to dial in a specific 75 mm to 150 mm extend position for indexing pallets in a compact profile-body assembly.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X150-75 with the SAUJ100X150-75
Choose the 75 mm adjust window if you need to trim the extend stroke on-site from the 150 mm maximum. Because this is a non-magnetic SKU, it cannot accept a sensor; the SAUJ requires CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify your side-load limits to prevent guide wear. Remember that the stop screw sets end position and does not hold loads on air loss.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X150-75
- ✓ 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 SUJ100X150-75 FAQ
Yes, the SUJ100X150-75 is discontinued. The direct replacement is the SAUJ100X150-75, which matches the 100 mm bore, 150 mm stroke, 1/2" 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 window is 75 mm, allowing you to trim the extend stroke on-site from the 150 mm maximum down to a 75 mm usable stroke. The stop sets end position and is not a load lock.
