This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X175-30S, 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 SUJ100X175-30S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X175-30S 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 SAUJ100X175-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X175-30S
The AirTAC SUJ100X175-30S is a double-acting, double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 145-175 mm extend out of the 175 mm nominal maximum. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable cushions.
This discontinued unit is fully replaced by the direct replacement SAUJ100X175-30S, which matches the bore, stroke, force, port, and FA/LB mounting. The upgrade path moves legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. Note the stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X175-30S 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 SAUJ100X175-30S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
Model Code: Airtac SUJ Adjustable Cylinder SUJ100X175-30S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×175 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ100X175-30S Is Used
Press Fit Tuning
Trimming the extend stroke by up to 30 mm on-site allows precise positioning for press fit operations without machining custom spacers.
Variable Length Diverter
Adjusting the extend end position lets a diverter gate accommodate different package sizes on a single conveyor line.
Adjustable End Stop
Setting a specific 145-175 mm extend endpoint provides a repeatable mechanical stop for pallet positioning before final clamping.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X175-30S with the SAUJ100X175-30S
To replace the discontinued SUJ100X175-30S, order the direct replacement SAUJ100X175-30S, which preserves the 100 mm bore, 175 mm stroke, 30 mm adjust window, 1/2 inch port, and FA/LB mounting. Choose the 30 mm adjust window when you need precise 145-175 mm extend tuning on-site; a fixed SAU plus external stop adds parts and length. Because this is an -S model, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches. For strokes at or above 300 mm, verify side-load limits to prevent guide wear. Mounting compatibility is strictly with the AirTAC SC series.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X175-30S
- ✓ 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 SUJ100X175-30S FAQ
Yes, the SUJ100X175-30S is discontinued. The direct replacement is the SAUJ100X175-30S, matching the 100 mm bore, 175 mm stroke, 30 mm adjust window, and 1/2 inch port. You must upgrade the piston magnet sensors from legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG series.
The external stop screw window is 30 mm, allowing you to shorten the 175 mm nominal extend stroke down to 145 mm on-site. The stop sets end position only and is not a load lock.
