This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X100-50, 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 SUJ32X100-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X100-50 is a double-acting profile-type standard cylinder with a Ø32mm bore and 100mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X100-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X100-50
The AirTAC SUJ32X100-50 is a double-acting double-rod profile cylinder with an adjustable extend stroke. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable window of 50-100 mm from the 100 mm nominal maximum. This compact extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore.
This SUJ model is discontinued and the direct replacement is the SAUJ32X100-50, matching the bore, stroke, force, 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, this cylinder cannot take a magnetic switch.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X100-50 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 SAUJ32X100-50 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 SUJ32X100-50 Is Used
Variable Depth Drilling
Adjusting the extend stroke on-site allows a drill head to hit precise material depths between 50 and 100 mm without machining custom spacers.
Variable Length Sorting Diverter
Tuning the extend stop lets a diverter arm accommodate changing package sizes on the fly, ensuring packages push cleanly to the correct lane.
Adjustable Mechanical Stop
Setting an external stop screw provides a hard, repeatable end position for pallets or workpieces when pneumatic cushions alone are insufficient.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X100-50 with the SAUJ32X100-50
To replace the discontinued SUJ32X100-50, order the direct replacement SAUJ32X100-50, which preserves the 32 mm bore, 100 mm nominal stroke, 50 mm adjust window, and 1/8" port. Choose the 50 mm adjust window if your fixture needs on-site extend tuning between 50 and 100 mm; for fixed positions, a standard SAU cylinder is simpler. Mounting uses basic, FA, or LB brackets (SC-series compatible). Because this SKU lacks a magnet, you cannot use sensors; the SAUJ supports CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X100-50
- ✓ 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 SUJ32X100-50 FAQ
Yes, the SUJ32X100-50 is discontinued. The direct replacement is the SAUJ32X100-50, which matches the 32 mm bore, 100 mm stroke, 50 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw window is 50 mm, meaning you can shorten the 100 mm nominal extend stroke down to 50 mm on-site. The stop sets the end position but is not a load lock.
