This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X75-10, 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 SUJ100X75-10
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X75-10 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 SAUJ100X75-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X75-10
The AirTAC SUJ100X75-10 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, giving a usable extend range of 65 to 75 mm. The stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so fit an external rod lock for held loads.
The direct replacement is the SAUJ100X75-10, matching the 100 mm bore, 75 mm stroke, force, and SC-series FA/LB mounting. Two key upgrades exist: the SAUJ uses current CMSG/DMSG/EMSG sensors whereas this SUJ used legacy CS1-B/DS1-B, and this specific non-magnet SKU cannot take a switch at all.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X75-10 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 SAUJ100X75-10 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 SUJ100X75-10 Is Used
Press Fit Tuning
Final insertion depth of a bearing or pin often varies by material tolerance; the 10 mm on-site trim window lets operators dial in the exact 65 to 75 mm extend position without changing the cylinder.
Variable Depth Flap Folding
Carton sealing machines handling mixed box heights use the external stop screw to quickly set the flap crease depth on-site for each batch, avoiding the need for fixed-stroke hardware swaps.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X75-10 with the SAUJ100X75-10
To replace the discontinued SUJ100X75-10, order the direct replacement SAUJ100X75-10, which preserves the 100 mm bore, 75 mm nominal stroke, 10 mm adjust window, 1/2" port, and FA/LB mounting. Choose the 10 mm adjust window if you need precise 65 to 75 mm extend tuning on-site, which often beats fitting a fixed-stroke SAU plus an external stop. Because this non-magnet SKU lacks a switch, if you need position sensing on the SAUJ you must add the -S suffix and use CMSG/DMSG/EMSG sensors instead of the SUJ's legacy CS1-B/DS1-B. For any stroke of 300 mm or longer, verify your side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X75-10
- ✓ 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 SUJ100X75-10 FAQ
Yes, the SUJ100X75-10 is discontinued. The direct replacement is the SAUJ100X75-10, which matches the 100 mm bore, 75 mm stroke, 10 mm adjust window, 1/2" port, and FA/LB mounting. The SAUJ also supports current CMSG/DMSG/EMSG sensors and offers an SAUF built-in-valve variant the SU line lacked.
The external stop screw provides a 10 mm adjust window, meaning the usable extend stroke is 65 to 75 mm. The stop sets end position but is not a load lock; use an external rod lock for held loads.
