This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X175-10S, 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 SUJ100X175-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X175-10S is a double-acting profile-type standard cylinder with a Ø100mm bore and 175mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X175-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X175-10S
The AirTAC SUJ100X175-10S is a double-acting double-rod profile cylinder with a 175 mm nominal stroke and an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 165-175 mm window. The stop sets the end position; it is not a load lock. It features a 1/2" port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
This SUJ unit is discontinued; the direct replacement is the SAUJ100X175-10S, matching the bore, stroke, force, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors (this model used legacy CS1-B/DS1-B switches) and offers the SAUF built-in-valve variant. Note that a plain cylinder drifts on air loss; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X175-10S 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 SAUJ100X175-10S 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 SUJ100X175-10S Is Used
Press Fit Calibration
Dialing in a 165-175 mm extend stroke on-site to seat bearings precisely without over-traveling, using the external stop screw to set the exact end position.
Variable Length Sealing
Adjusting the extend stroke by up to 10 mm to accommodate carton height variations on a packaging line, ensuring consistent flap folding without repositioning the cylinder.
End-of-Stroke Dampening Setup
Trimming the extend stroke to match a changing workpiece profile, relying on the 29 mm adjustable air cushion to decelerate the load near the newly set end position.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X175-10S with the SAUJ100X175-10S
To replace the discontinued SUJ100X175-10S, order the direct replacement SAUJ100X175-10S, which retains the 100 mm bore, 175 mm stroke, 1/2" port, and FA/LB mounting. Choose the 10 mm adjust window when you need precise 165-175 mm extend tuning without adding external stops. Because this is an -S model, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches on the SAUJ. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X175-10S
- ✓ 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 SUJ100X175-10S FAQ
Yes, the SUJ100X175-10S is discontinued. The direct replacement is the SAUJ100X175-10S, which matches the 100 mm bore, 175 mm stroke, 1/2" port, and FA/LB mounting. You must upgrade the position sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.
The external stop screw window is 10 mm, allowing you to trim the 175 mm nominal extend stroke down to 165 mm on-site. The stop sets end position but is not a load lock.
