This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X175-40, 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 SUJ100X175-40
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X175-40 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 SAUJ100X175-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X175-40
The AirTAC SUJ100X175-40 is a discontinued double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40 mm on-site, giving a usable 135-175 mm extension out of the 175 mm nominal maximum. It features a 1/2" port, a Ø25 mm piston rod with an M20x1.5 thread, and 29 mm adjustable air cushions at each end.
Because this model is end-of-life, the direct replacement is the SAUJ100X175-40, which retains the same compact profile body, bore, stroke, force, adjust window, and FA/LB mounting. The SAUJ upgrade shifts sensing to current CMSG/DMSG/EMSG sensors, as this legacy unit used CS1-B/DS1-B switches. Note this SKU has no magnet and cannot take a sensor; the stop screw sets end position but is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X175-40 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 SAUJ100X175-40 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 SUJ100X175-40 Is Used
Press Fit Tuning
Allows operators to dial in the exact 135-175 mm extend position on-site for pressing bearings without machining hard stops.
Variable Length Diverter
Adjusts the extend stroke on a sorting line to accommodate different package sizes on the fly.
Adjustable Stop Gate
Provides a field-tunable end position for pallet stops, letting maintenance shorten the stroke by up to 40 mm as layout changes.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X175-40 with the SAUJ100X175-40
To replace the discontinued SUJ100X175-40, order the direct replacement SAUJ100X175-40, which matches the 100 mm bore, 175 mm nominal stroke, 40 mm adjust window, 1/2" port, and FA/LB mounting. The -40 adjust window is ideal if your end position needs field tuning between 135 and 175 mm, which often beats installing a fixed-stroke SAU plus an external stop. This non-magnetic SKU cannot accept sensors, but if you upgrade to an -S SAUJ, you must use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding. The stop screw sets end position only; it is not a lock, so add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X175-40
- ✓ 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 SUJ100X175-40 FAQ
Yes, the AirTAC SUJ100X175-40 is discontinued. The direct replacement is the SAUJ100X175-40, which shares the same 100 mm bore, 175 mm stroke, 40 mm adjust window, 1/2" 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 allows you to trim the extend stroke by up to 40 mm on-site, yielding a usable 135-175 mm extension. The stop sets end position but is not a load lock.
