This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X125-50S, 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 SUJ32X125-50S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X125-50S is a double-acting profile-type standard cylinder with a Ø32mm bore and 125mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ32X125-50S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X125-50S
The AirTAC SUJ32X125-50S is a double-acting, double-rod profile cylinder with a 125 mm nominal stroke and a 50 mm external stop screw window, letting you trim the extend stroke down to 75 mm on-site. The stop sets the end position but is not a load lock; use an external rod lock for held loads. This 32 mm bore uses a 1/8" port, M10x1.25 rod thread, and 21 mm adjustable cushions.
This SUJ32X125-50S (with -S magnet for legacy CS1-B/DS1-B switches) is discontinued. The direct replacement is the SAUJ32X125-50S, matching the bore, stroke, 50 mm adjust window, force, and FA/LB mounting. The SAUJ upgrades to current CMSG/DMSG/EMSG sensors and offers the SAUF built-in-valve variant. The compact profile barrel is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X125-50S 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 SAUJ32X125-50S 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 SUJ32X125-50S Is Used
Variable Pitch Feed
Adjusting the extend stroke on-site by up to 50 mm allows a single 125 mm cylinder to drive multiple varying material pitches without swapping the entire actuator.
Sorting Diverter Setup
Trimming the extend end position lets a diverter gate accommodate different package sizes on the fly, ensuring precise routing without mechanical spacers.
Adjustable Forming Depth
The 50 mm stop screw window provides quick depth tuning for packaging presses, accommodating various container heights directly at the machine.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X125-50S with the SAUJ32X125-50S
To replace the discontinued SUJ32X125-50S, order the direct replacement SAUJ32X125-50S, which retains the 32 mm bore, 125 mm stroke, 1/8" port, and 50 mm adjust window. Choose the 50 mm adjust window if your extend stroke needs on-site tuning between 75 mm and 125 mm; a fixed SAU cylinder plus external stop is bulkier. The SAUJ accepts FA and LB mounts (SC-series compatible) and uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X125-50S
- ✓ 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 SUJ32X125-50S FAQ
Yes, the SUJ32X125-50S is discontinued. The direct replacement is the SAUJ32X125-50S, which matches the 32 mm bore, 125 mm stroke, 1/8" port, and 50 mm adjust window. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 50 mm external stop screw window allows you to shorten the 125 mm extend stroke down to 75 mm on-site. The stop sets end position and is not a load lock.
