This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X175-75, 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 SUJ32X175-75
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X175-75 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 SAUJ32X175-75, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X175-75
The AirTAC SUJ32X175-75 is a double-acting double-rod profile cylinder with an adjustable stroke, now discontinued and directly replaced by the SAUJ32X175-75. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 100 to 175 mm stroke. The nominal 175 mm is the maximum. This stop sets the end position but is not a load lock. The SAUJ direct keeps the same body, force, and SC mounting.
The SAUJ upgrades sensing to current CMSG/DMSG/EMSG sensors (this SKU lacks a magnet and cannot take a switch, unlike the legacy CS1-B/DS1-B). A plain cylinder drifts on air loss; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X175-75 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 SAUJ32X175-75 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 SUJ32X175-75 Is Used
Variable Depth Forming
Adjust the extend stroke on-site to press parts to different depths without swapping the entire cylinder.
Variable Length Sorting
Trim the extend stroke by up to 75 mm to push varying package sizes onto diverter lanes accurately.
Adjustable Stop Positioning
Fine-tune the end position to act as an adjustable physical stop for incoming materials on a line.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X175-75 with the SAUJ32X175-75
To replace the discontinued SUJ32X175-75, order the direct replacement SAUJ32X175-75, which preserves the 32 mm bore, 175 mm max stroke, 75 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 75 mm adjust window if you need to trim the extend stroke on-site between 100 and 175 mm. Since this non-magnetic SKU cannot take a switch, the SAUJ upgrade lets you use current CMSG/DMSG/EMSG sensors. For this 175 mm stroke, ensure your mechanical setup handles side-load forces. Remember the stop screw sets end position, not a lock; add an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X175-75
- ✓ 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 SUJ32X175-75 FAQ
Yes, the SUJ32X175-75 is discontinued. The direct replacement is the SAUJ32X175-75, which matches the 32 mm bore, 175 mm stroke, 75 mm adjust window, 1/8" port, and FA/LB mounting.
The external stop screw provides a 75 mm adjust window, allowing you to trim the extend stroke from the 175 mm maximum down to 100 mm on-site.
