This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X175-20S, 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 SUJ32X175-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X175-20S 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 SAUJ32X175-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X175-20S
The AirTAC SUJ32X175-20S is a double-acting, double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 155-175 mm extension out of the 175 mm nominal maximum. This compact extruded-aluminum body is notably shorter than an ISO 15552 unit of the same bore. This specific SUJ variant is discontinued; the direct replacement is the SAUJ32X175-20S, which matches the bore, stroke, force, and mounting.
The stop screw strictly sets the end position and is not a load lock. Because this is an -S model, it includes a piston magnet for legacy CS1-B/DS1-B switches; upgrading to the SAUJ requires switching to current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X175-20S 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 SAUJ32X175-20S 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 SUJ32X175-20S Is Used
Diverter Gate Positioning
Allows maintenance teams to fine-tune the 155-175 mm extend reach on-site to hit a moving conveyor diverter gate perfectly without machining custom spacers.
Variable Depth Carton Sealing
Provides a 20 mm field adjustment to accommodate slight fluctuations in packaging flap height, ensuring consistent pressing force during the sealing cycle.
Prototype Part Ejection
Ideal for test fixtures where the exact ejection distance of a 32 mm bore cylinder must be dialed in by hand during short prototype runs.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X175-20S with the SAUJ32X175-20S
To replace the discontinued SUJ32X175-20S, order the direct replacement SAUJ32X175-20S, which retains the 32 mm bore, 175 mm max stroke, 20 mm adjust window, 1/8" port, and SC-series FA/LB mounting compatibility. Choose the 20 mm adjust window if you need precise on-site extend tuning between 155 and 175 mm. For the -S magnet version, note that the SAUJ upgrade necessitates a sensor change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. Since the 175 mm stroke is under 300 mm, side-load limits are less critical, but always ensure external rod locks or pilot-operated check valves are used for load holding, as the stop screw and air cushions only decelerate and do not lock the piston.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X175-20S
- ✓ 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 SUJ32X175-20S FAQ
Yes, the AirTAC SUJ32X175-20S is discontinued. The direct replacement is the SAUJ32X175-20S. It matches the 32 mm bore, 175 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. The main upgrade requirement is swapping legacy CS1-B/DS1-B sensors for current CMSG/DMSG/EMSG switches.
The external stop screw provides a 20 mm adjustment window, allowing the extend stroke to be shortened from the 175 mm maximum down to 155 mm on-site.
