This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X75-50S, 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 SUJ32X75-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X75-50S is a double-acting profile-type standard cylinder with a Ø32mm bore and 75mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X75-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X75-50S
The AirTAC SUJ32X75-50S is a double-acting, double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 50 mm on-site. With a nominal 75 mm stroke, the usable extend range is 25-75 mm. The stop screw sets the end position but is not a load lock; an external rod lock is required to hold loads on air loss.
This discontinued model is fully replaced by the SAUJ32X75-50S, which preserves the 1/8" port, M10x1.25 rod thread, and 21 mm cushions. The direct SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches on this -S magnet model. The compact extruded aluminum barrel is shorter than standard cylinders of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X75-50S 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 SAUJ32X75-50S 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 SUJ32X75-50S Is Used
Variable Depth Boring
Trimming the 75 mm extend stroke down to 25 mm on-site to set precise boring depths in soft materials without swapping the cylinder.
Adjustable Pusher Stops
Tuning the extend end position to handle varying package sizes on a 1/8" port pneumatic conveyor line without mechanical spacers.
Dynamic Sorting Diverts
Field-adjusting the divert stroke by up to 50 mm to accommodate changing product profiles in compact sorting stations.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X75-50S with the SAUJ32X75-50S
To replace the discontinued SUJ32X75-50S, order the direct replacement SAUJ32X75-50S, which matches the 32 mm bore, 75 mm nominal stroke, 50 mm adjust window, 1/8" port, and FA/LB mounting. Choose the 50 mm adjust window if you need to trim the extend stroke on-site from 75 mm down to 25 mm. Note that the SAUJ uses CMSG/DMSG/EMSG sensors to replace the legacy CS1-B/DS1-B switches. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X75-50S
- ✓ 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 SUJ32X75-50S FAQ
Yes, the SUJ32X75-50S is discontinued. The direct replacement is the SAUJ32X75-50S, which matches the 32 mm bore, 75 mm stroke, 50 mm adjust window, and 1/8" port. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw provides a 50 mm adjust window, allowing the 75 mm extend stroke to be shortened to 25 mm on-site. The stop sets end position but is not a load lock.
