This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X175-50S, 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 SUJ100X175-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X175-50S 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 SAUJ100X175-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X175-50S
The AirTAC SUJ100X175-50S is a discontinued double-acting double-rod profile cylinder with a 100mm bore and 175mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 50mm on-site, yielding a usable 125-175mm window. It features a 1/2 inch port, M20x1.5 rod thread, and 29mm adjustable cushions. This unit is discontinued; the direct replacement is the SAUJ100X175-50S, matching the bore, stroke, 1/2 inch port, and SC-series FA/LB mounting.
The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors, replacing the legacy CS1-B/DS1-B switches used here, and the SAU family adds an SAUF built-in-valve variant the SU line lacked. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X175-50S 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 SAUJ100X175-50S 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 SUJ100X175-50S Is Used
Variable Pitch Indexing
Adjusting the extend stroke on-site by up to 50mm allows a single 100mm bore cylinder to drive multiple product pitches without swapping the whole actuator.
Transfer Pusher Tuning
Trimming the extend stroke lets operators dial in the exact push distance for varying package sizes on a transfer line, using the 125-175mm window.
Pallet Stop Positioning
The external stop screw provides a hard mechanical end position for pallet stops, offering field flexibility without re-mounting the cylinder.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X175-50S with the SAUJ100X175-50S
To replace this discontinued model, order the SAUJ100X175-50S; it is a direct swap retaining the 100mm bore, 175mm nominal stroke, 1/2 inch port, and FA/LB mounting. Choose the 50mm adjust window if your fixture needs field tuning between 125mm and 175mm extend lengths. Because this is an -S model, you must migrate from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors on the SAUJ. For strokes of 300mm or longer, verify side-load limits to prevent guide wear. The external stop sets end position only; it is not a lock, so add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X175-50S
- ✓ 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
