This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X175-100S, 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 SUJ50X175-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ50X175-100S is a double-acting profile-type standard cylinder with a Ø50mm bore and 175mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ50X175-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X175-100S
The AirTAC SUJ50X175-100S is a double-acting double-rod profile cylinder with a 175 mm nominal stroke and a 1/4" port. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 75-175 mm window. The stop sets the end position but is not a load lock; use an external rod lock for held loads.
This SUJ50X175-100S unit is discontinued; the direct replacement is the SAUJ50X175-100S, retaining the bore, stroke, force, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy model uses CS1-B/DS1-B switches. The compact extruded barrel is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X175-100S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAUJ50X175-100S 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 SUJ50X175-100S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | 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 SUJ50X175-100S Is Used
Variable Depth Diving Heads
Adjusts the extend stroke on-site for material thickness changes without swapping the entire cylinder.
Variable Length Sorting Diverters
Trims the extend position to handle changing package sizes on the fly, ensuring precise routing.
Adjustable Height Lift Stops
Sets exact lift end positions for varying pallet heights, using the stop screw to tune the extend limit.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X175-100S with the SAUJ50X175-100S
To replace the discontinued SUJ50X175-100S, order the direct replacement SAUJ50X175-100S; it preserves the 50 mm bore, 175 mm nominal stroke, 100 mm adjust window, 1/4" port, and FA/LB mounting. Select the adjust window based on your maximum needed trim (here, shortening extend by up to 100 mm on-site for a 75-175 mm usable range). 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 rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X175-100S
- ✓ 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 SUJ50X175-100S FAQ
Yes, the SUJ50X175-100S is discontinued. The direct replacement is the SAUJ50X175-100S, which matches the 50 mm bore, 175 mm 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 switches.
The external stop screw provides a 100 mm adjust window, allowing you to trim the 175 mm nominal extend stroke down to 75 mm on-site. The stop sets end position and is not a load lock.
