This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X125-50, 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 SUJ32X125-50
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X125-50 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 SAUJ32X125-50, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X125-50
The AirTAC SUJ32X125-50 is a double-acting double-rod profile cylinder with a 32 mm bore and 125 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, yielding a usable 75 to 125 mm end position. This compact aluminum barrel is shorter than an ISO 15552 unit of the same bore. Operating pressure is 0.15 to 1.0 MPa, speed is 30-800 mm/s, and it features a 1/8" port with an M10x1.25 rod thread.
This SUJ model is discontinued and the direct replacement is the SAUJ32X125-50, which matches the bore, stroke, 50 mm adjust window, force, port, and FA/LB mounting. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. Because this SKU lacks a magnet (-S), it cannot take a switch, whereas the SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X125-50 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 SAUJ32X125-50 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 SUJ32X125-50 Is Used
Variable Pitch Indexing
Dialing the extend stroke on-site by up to 50 mm allows a single 32 mm bore cylinder to drive multiple varying pitch lengths without swapping the whole actuator.
Adjustable Transfer Pusher
Trimming the extend stroke lets operators reposition a transfer pusher endpoint precisely for mixed product sizes running on the same line.
Carton Flap Folding
Field-tuning the 125 mm maximum stroke down to 75 mm provides exact flap folding contact points for changing carton depths without mechanical rework.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X125-50 with the SAUJ32X125-50
To replace the discontinued SUJ32X125-50, order the direct replacement SAUJ32X125-50, which preserves the 32 mm bore, 125 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 between 75 and 125 mm; this often beats installing a fixed-stroke SAU plus an external stop. For mounting, use SC-series compatible FA or LB brackets. Since this specific SKU has no magnet, it cannot support sensing; the SAUJ upgrade requires CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. If your stroke is 300 mm or longer, verify side-load limits to prevent rod bearing wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X125-50
- ✓ 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 SUJ32X125-50 FAQ
Yes, the SUJ32X125-50 is discontinued. The direct replacement is the SAUJ32X125-50, matching the 32 mm bore, 125 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.
The external stop screw window is 50 mm, allowing you to shorten the 125 mm maximum extend stroke down to 75 mm on-site. The stop sets end position only; it is not a load lock.
