This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X175-50S, 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 SUJ32X175-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X175-50S is a double-acting profile-type standard cylinder with a Ø32mm bore and 175mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X175-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X175-50S
The AirTAC SUJ32X175-50S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 125 to 175 mm extend window from the 175 mm nominal maximum. This discontinued unit is fully replaced by the SAUJ32X175-50S.
The direct replacement SAUJ32X175-50S retains the exact bore, stroke, force, port, and FA/LB mounting. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S magnet model.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X175-50S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAUJ32X175-50S 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 SUJ32X175-50S Is Used
Custom Clamp Positioning
Allows operators to dial in the exact 125 to 175 mm extend reach on-site to accommodate varying workpiece heights without swapping cylinders.
Variable Length Diverter
Provides adjustable stroke for routing differently sized packages on a line, fine-tuning the pusher extension up to 50 mm to prevent over-travel.
Adjustable Stop Gate
Sets a precise physical stop for incoming pallets, enabling quick field adjustments to the gate position as pallet dimensions change.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X175-50S with the SAUJ32X175-50S
To replace the discontinued SUJ32X175-50S, specify the direct replacement SAUJ32X175-50S, which matches the 32 mm bore, 175 mm stroke, 50 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 50 mm adjust window if your application requires field tuning the extend stroke down to 125 mm. Because this model has the -S magnet, you must upgrade from legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. For stroke lengths of 300 mm or greater, verify side-load limits to prevent excessive guide wear. Remember 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 → SAUJ32X175-50S
- ✓ 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
Airtac SUJ Adjustable Cylinder SUJ32X175-50S FAQ
Yes, the SUJ32X175-50S is discontinued. The direct replacement is the AirTAC SAUJ32X175-50S, which matches the 32 mm bore, 175 mm stroke, 50 mm adjust window, 1/8" port, and FA/LB mounting. You will need to upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The external stop screw provides a 50 mm adjustment window, allowing you to shorten the extend stroke from the 175 mm nominal maximum down to 125 mm on-site.
