This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X100-75N, 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 SUJ100X100-75N
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X100-75N is a double-acting profile-type standard cylinder with a Ø100mm bore and 100mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X100-75N, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X100-75N
The AirTAC SUJ100X100-75N 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 25-100 mm stroke from the 100 mm nominal maximum. 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 SAUJ100X100-75N, matching the 100 mm bore, stroke, force, and SC-series FA/LB mounting. This SKU lacks a magnet and cannot take a switch, whereas upgrading to the SAUJ enables current CMSG/DMSG/EMSG sensors (this SUJ used legacy CS1-B/DS1-B).

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X100-75N 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 SAUJ100X100-75N 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 SUJ100X100-75N Is Used
Variable Depth Forming
Pressing or stamping operations requiring field stroke tuning to accommodate different material thicknesses without swapping the entire cylinder.
Adjustable Diverter Arms
Routing packages of varying sizes on a line by trimming the extend stroke on-site to hit precise sorting positions.
Variable Height Stops
Palletizing cells where the external stop screw shortens the extend stroke to create multiple physical end-stop heights for different pallet stacks.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X100-75N with the SAUJ100X100-75N
To replace the discontinued SUJ100X100-75N, order the direct replacement SAUJ100X100-75N; the 100 mm bore, 100 mm nominal stroke, 1/2 inch port, and FA/LB mounting are unchanged. Choose the 75 mm adjust window if you need to trim the extend stroke down to a 25 mm minimum on-site. Because this N-seal SKU has no magnet, it cannot take a switch; the SAUJ upgrade supports CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X100-75N
- ✓ 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 SUJ100X100-75N FAQ
Yes, the SUJ100X100-75N is discontinued. The direct replacement is the SAUJ100X100-75N, which matches the 100 mm bore, 100 mm nominal stroke, 75 mm adjust window, 1/2 inch 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 75 mm adjust window, allowing you to trim the extend stroke from the 100 mm maximum down to a 25 mm minimum on-site.
