This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X175-100S, 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 SUJ40X175-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X175-100S is a double-acting profile-type standard cylinder with a Ø40mm bore and 175mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X175-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X175-100S
The AirTAC SUJ40X175-100S is a discontinued double-acting double-rod profile cylinder with a 175 mm maximum extend stroke and an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 75-175 mm window. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore.
The direct replacement is the SAUJ40X175-100S, sharing the same bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this SUJ used legacy CS1-B/DS1-B switches. The stop screw sets the end position but is not a load lock; an external rod lock is required to hold loads on air loss.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X175-100S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAUJ40X175-100S 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 SUJ40X175-100S Is Used
Variable Depth Drilling
Adjusting the extend stroke on-site by up to 100 mm allows a drill head to hit multiple material depths without swapping the entire cylinder.
Variable Length Sorting Diverter
Trimming the extend stroke from 175 mm down to 75 mm accommodates varying package sizes on a packaging line without repositioning the actuator.
Adjustable Height Lift Stop
The external stop screw sets the precise extend end position for tiered shelving heights, providing field flexibility for changing warehouse layouts.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X175-100S with the SAUJ40X175-100S
To replace this discontinued SUJ40X175-100S, specify the SAUJ40X175-100S, which is a direct match for the 40 mm bore, 175 mm max stroke, 100 mm adjust window, 1/4" port, and FA/LB mounting. The 100 mm adjust window is ideal when you need precise field tuning of the extend stroke from 75 to 175 mm. The -S suffix indicates a piston magnet; the SAUJ uses current CMSG/DMSG/EMSG sensors instead of the SUJ's legacy CS1-B/DS1-B. For strokes at or above 300 mm, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X175-100S
- ✓ 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 SUJ40X175-100S FAQ
Yes, the SUJ40X175-100S is discontinued. The direct replacement is the SAUJ40X175-100S, which matches the 40 mm bore, 175 mm max stroke, 100 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw provides a 100 mm adjust window, allowing you to shorten the 175 mm maximum extend stroke down to 75 mm on-site. The stop sets end position and is not a load lock.
