This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X175-40, 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 SUJ32X175-40
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X175-40 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 SAUJ32X175-40, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X175-40
The AirTAC SUJ32X175-40 is a double-acting, double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 135-175 mm stroke from the 175 mm nominal maximum. It features a 1/8" port, a 12 mm rod, and 21 mm adjustable cushions.
This SUJ model is discontinued; the direct replacement is the SAUJ32X175-40, matching the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches. As a non-magnet SKU, it cannot take a position switch. The stop screw sets 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 SAUJ32X175-40 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 SAUJ32X175-40 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 SUJ32X175-40 Is Used
Custom Ejector Stroke
Trimming the extend stroke by up to 40 mm on-site allows precise ejection of varied part sizes without machining a custom-length cylinder.
Adjustable Diverter Arm
Field-tuning the 135-175 mm stroke window lets operators reposition a diverter arm exactly where packages meet the belt.
Variable Stop Position
The external stop screw provides a hard mechanical end position for pallets or racks, adjustable within the 40 mm window as layout needs evolve.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X175-40 with the SAUJ32X175-40
To replace the discontinued SUJ32X175-40, order the direct replacement SAUJ32X175-40, which preserves the 32 mm bore, 175 mm stroke, 1/8" port, and FA/LB mounting. Choose the 40 mm adjust window if your extend stroke needs on-site tuning between 135 and 175 mm. Because this is a non-magnet SKU, it cannot accept sensors; the SAUJ upgrade supports CMSG/DMSG/EMSG switches (replacing legacy CS1-B/DS1-B). For this 175 mm stroke, verify side-load limits. The stop screw sets end position only—it is not a lock; add an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X175-40
- ✓ 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 SUJ32X175-40 FAQ
Yes, the SUJ32X175-40 is discontinued. The direct replacement is the SAUJ32X175-40, which matches the 32 mm bore, 175 mm stroke, 1/8" port, and FA/LB mounting. The SAUJ also supports current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The external stop screw trims the extend stroke by up to 40 mm on-site, giving a usable 135-175 mm stroke. The stop sets end position but is not a load lock.
