This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ32X125-100, 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 SUJ32X125-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ32X125-100 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 SAUJ32X125-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ32X125-100
The AirTAC SUJ32X125-100 is a double-acting double-rod adjustable-stroke profile cylinder, now discontinued. The external stop screw lets you trim the extend stroke by up to 100 mm on-site, giving a usable 25-125 mm range from the 125 mm nominal maximum. The direct replacement is the SAUJ32X125-100, matching the bore, stroke, force, port, and SC-series 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 non-magnet SKU lacks a switch, and used legacy CS1-B/DS1-B sensors, upgrading to the SAUJ enables current CMSG/DMSG/EMSG sensors. Its compact profile barrel is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ32X125-100 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 SAUJ32X125-100 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 SUJ32X125-100 Is Used
Variable Pitch Pushing
Feeding different length blanks on a single line by dialing the extend stroke from 25 to 125 mm without swapping the cylinder.
Adjustable Diverter Gate
Tuning a sorting gate reach on-site to handle varying package widths precisely without disassembling the pneumatic assembly.
Crush-Sensitive Forming
Setting a precise mechanical end position for a sealing head to protect delicate contents, using the screw as a hard physical stop.
Replacing the Airtac SUJ Adjustable Cylinder SUJ32X125-100 with the SAUJ32X125-100
To replace the discontinued SUJ32X125-100, order the exact direct replacement SAUJ32X125-100. Choose the adjust window based on your maximum needed extend: this 100 mm window yields a 25-125 mm usable stroke. Mounting uses the basic foot FA or LB style compatible with AirTAC SC series parts. This non-magnet model cannot take a switch; the SAUJ upgrade supports CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B. For stroke lengths of 300 mm or longer, verify your side-load limits to prevent guide wear. The stop screw sets end position only; it is not a lock, so add an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ32X125-100
- ✓ 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 SUJ32X125-100 FAQ
Yes, the SUJ32X125-100 is discontinued. The direct replacement is the SAUJ32X125-100, which matches the 32 mm bore, 125 mm stroke, 100 mm adjust window, 1/8" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The double-acting double-rod cylinder pushes 402 N and pulls 345 N at 0.5 MPa, pushing 563 N at 0.7 MPa and 724 N at 0.9 MPa, with an 82 kgf theoretical max at 1.0 MPa. The external stop screw window is 100 mm, meaning you can trim the extend stroke by up to 100 mm on-site, yielding a usable 25-125 mm range from the 125 mm nominal maximum. The stop sets end position but is not a load lock.
