This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X175-30, 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 SUJ32X175-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X175-30 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 SAUJ32X175-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X175-30
The AirTAC SUJ32X175-30 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 145-175 mm range from the 175 mm nominal maximum. This discontinued unit used legacy CS1-B/DS1-B sensors and lacks a magnet, so it cannot accept a magnetic switch.
The direct replacement is the SAUJ32X175-30, which preserves the exact bore, stroke, force, port, and FA/LB mounting. Upgrading to the SAUJ moves you to current CMSG/DMSG/EMSG sensors. Note the stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X175-30 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 SAUJ32X175-30 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 SUJ32X175-30 Is Used
Variable Pitch Indexing
Trimming the extend stroke by up to 30 mm on-site allows a 32 mm bore actuator to alter the push distance for parts of varying widths without swapping the cylinder.
Adjustable Transfer Pusher
A 145-175 mm extend window lets operators fine-tune where a product stops on the belt, adapting to package size variations on the fly.
Prototype End-Stop Tuning
During fixture development, the external stop screw provides exact end-position adjustment for the 175 mm stroke, avoiding machined spacer modifications.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X175-30 with the SAUJ32X175-30
To replace the discontinued SUJ32X175-30, order the direct replacement SAUJ32X175-30, which retains the 1/8" port, 175 mm max stroke, 30 mm adjust window, and FA/LB mounting. Choose the 30 mm adjust window when you need precise 145-175 mm field tuning. Because this non-magnet SKU cannot take a switch, migrating to the SAUJ lets you fit CMSG/DMSG/EMSG sensors. For this 175 mm stroke, keep side-load within standard SC-series tolerances. The stop screw sets end position but is not a lock; add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X175-30
- ✓ 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 SUJ32X175-30 FAQ
Yes, the SUJ32X175-30 is discontinued. The direct replacement is the SAUJ32X175-30, which matches the 32 mm bore, 175 mm stroke, 30 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ upgrades you to current CMSG/DMSG/EMSG sensors.
It is a double-acting double-rod cylinder with a 30 mm adjust window (usable extend 145-175 mm). The stop screw sets end position only and does not lock the load.
