This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X75-50, 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 SUJ100X75-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X75-50 is a double-acting profile-type standard cylinder with a Ø100mm bore and 75mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X75-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X75-50
The AirTAC SUJ100X75-50 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 25-75 mm extend out of the 75 mm nominal maximum. Because it is discontinued, the direct replacement is the SAUJ100X75-50, which retains the 100 mm bore, 1/2" port, M20x1.5 rod thread, and 29 mm adjustable cushions. The stop screw sets the end position but is not a load lock.
The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used here. Note this specific SKU lacks a magnet and cannot take a switch.

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 SAUJ100X75-50 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 SUJ100X75-50 Is Used
Variable Stroke Clamping
Adjusting the extend stop on-site allows a single fixture to clamp parts of varying heights without reprogramming the pneumatic controller.
Adjustable Transfer Stops
Tuning the extend stroke lets operators change the physical stopping distance for different package sizes on a packaging line.
Modular Diverter Arms
Field-trimming the extend stroke enables a diverter arm to reach multiple conveyor lanes without swapping out the entire cylinder.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X75-50 with the SAUJ100X75-50
To replace the discontinued SUJ100X75-50, order the direct replacement SAUJ100X75-50; the profile body, 1/2" port, 25 mm rod, and FA/LB mounting match exactly. Choose the 50 mm adjust window if your fixture needs field-tuning the extend stroke down to 25 mm; if fixed positioning is acceptable, a standard SAU avoids the stop screw. Since this SKU has no magnet, sensing requires the -S variant which uses CMSG/DMSG/EMSG sensors on the SAUJ. For strokes at or exceeding 300 mm, verify side-load limits to prevent guide wear. Remember the adjust stop sets end position only; use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X75-50
- ✓ 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 SUJ100X75-50 FAQ
Yes, the SUJ100X75-50 is discontinued. The direct replacement is the SAUJ100X75-50, which matches the 100 mm bore, 75 mm stroke, 50 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw provides a 50 mm adjust window, allowing you to shorten the 75 mm nominal extend stroke down to 25 mm on-site. The stop sets end position and is not a load lock.
