This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X160-20S, 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 SUJ32X160-20S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X160-20S is a double-acting profile-type standard cylinder with a Ø32mm bore and 160mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X160-20S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X160-20S
The AirTAC SUJ32X160-20S 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 140-160 mm extend window from the 160 mm nominal maximum. The 1/8" port and extruded aluminum profile barrel make it notably shorter than an ISO 15552 cylinder of the same bore.
This SUJ32X160-20S unit is DISCONTINUED; the direct replacement is the SAUJ32X160-20S, matching the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy model used CS1-B/DS1-B switches. Note that the stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X160-20S 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 SAUJ32X160-20S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -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 SUJ32X160-20S Is Used
Variable Pitch Indexing
Dialing in the exact extend stop on a 32 mm bore cylinder for short-run parts where the 140-160 mm extend window must be tuned per batch without swapping the entire actuator.
Adjustable Diverter Gate
Setting a precise push distance for routing varying package sizes on a line, using the 20 mm on-site stroke trim to accommodate different carton depths on the fly.
Custom Format Stops
Fine-tuning the end position of a sorting pusher by trimming the extend stroke up to 20 mm, allowing rapid adaptation to new product dimensions without reprogramming the motion controller.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X160-20S with the SAUJ32X160-20S
To replace the discontinued SUJ32X160-20S, specify the direct replacement SAUJ32X160-20S, which retains the 32 mm bore, 160 mm nominal stroke, 20 mm adjust window, and 1/8" port. Choose the 20 mm adjust window if your application requires field tuning the extend stroke down to 140 mm. Mounting remains compatible with AirTAC SC series FA and LB brackets. Because this configuration includes the -S magnet, you must migrate from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors. For strokes of 300 mm or longer, verify the side-load limits to prevent excessive rod bearing wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X160-20S
- ✓ 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 SUJ32X160-20S FAQ
Yes, the AirTAC SUJ32X160-20S is discontinued. The direct replacement is the SAUJ32X160-20S, which matches the 32 mm bore, 160 mm stroke, 20 mm adjust window, 1/8" port, and FA/LB mounting. You will need to upgrade the position sensing from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensors.
The external stop screw provides a 20 mm adjust window, allowing you to shorten the 160 mm nominal extend stroke down to 140 mm on-site. The stop sets the end position but is not a load lock.
