This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X80-10, 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 SUJ100X80-10
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X80-10 is a double-acting profile-type standard cylinder with a Ø100mm bore and 80mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X80-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X80-10
The AirTAC SUJ100X80-10 is a double-acting double-rod adjustable-stroke profile cylinder, now officially discontinued. An external stop screw allows you to trim the extend stroke by up to 10 mm on-site, giving a usable extend window of 70-80 mm from the 80 mm nominal maximum. This 100 mm bore profile body is notably shorter than an ISO 15552 unit of the same size and operates via a 1/2 inch port with a 25 mm rod.
The direct replacement is the SAUJ100X80-10, which matches the original bore, stroke, 10 mm adjust window, force, and SC-series FA/LB mounting. During the swap, note that this non-magnetic SUJ SKU cannot take a switch, while the SAUJ family upgrades sensing to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B. Remember the stop screw sets end position but is not a load lock; use an external rod lock for held 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 SAUJ100X80-10 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 SUJ100X80-10 Is Used
Press Fit Tuning
Allows operators to dial in the exact 70-80 mm extend position for seating bearings without machining hard stops.
Variable Length Diverter
Adjusts the extend stroke on-site to deflect different package sizes on a packaging line.
Gauge Positioning Stop
Provides a micro-adjustable physical end stop for material feeding, trimming the extend by up to 10 mm.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X80-10 with the SAUJ100X80-10
To replace the discontinued SUJ100X80-10, order the exact direct replacement SAUJ100X80-10, which preserves the 100 mm bore, 80 mm nominal stroke, 10 mm adjust window, 1/2 inch port, and FA/LB mounting. Choose the 10 mm adjust window when you need precise field tuning of the extend endpoint within a 70-80 mm range. Because this specific SKU lacks a magnet (-S), it cannot support sensing; the SAUJ upgrade path utilizes CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For stroke lengths at or above 300 mm, carefully verify side-load constraints to prevent guide wear. Finally, the external stop screw merely sets the end position and does not function as a load lock—maintain live air or install an external rod lock for holding loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X80-10
- ✓ 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 SUJ100X80-10 FAQ
Yes, the SUJ100X80-10 is discontinued. The direct replacement is the SAUJ100X80-10, matching the 100 mm bore, 80 mm stroke, 10 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 100 mm bore double-acting double-rod cylinder pushes 3927 N and pulls 3681 N at 0.5 MPa, pushing 5497 N at 0.7 MPa and 7068 N at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The external stop screw allows you to trim the extend stroke by up to 10 mm on-site, yielding a usable extend window of 70-80 mm. This stop sets end position and is not a load lock.
