This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ100X125-100, 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 SUJ100X125-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X125-100 is a double-acting profile-type standard cylinder with a Ø100mm bore and 125mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ100X125-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X125-100
The AirTAC SUJ100X125-100 is a double-acting double-rod profile cylinder with a 125 mm nominal stroke and a 100 mm external stop screw window, allowing you to trim the extend stroke on-site down to a 25 mm minimum. The SUJ series is discontinued; the direct replacement is the SAUJ100X125-100, retaining the same bore, stroke, force, port, and FA/LB mounting.
Because the stop screw only sets the end position and is not a lock, loads drift on air loss—use an external rod lock for holding. This non-magnet SKU cannot take a switch. Upgrading to the SAUJ moves you from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors while keeping the compact profile shorter than an ISO 15552 cylinder.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X125-100 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUJ100X125-100 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 SUJ100X125-100 Is Used
Variable-Length Pressing
Apply up to 7068 N of clamping force on parts of varying heights, dialing the extend stroke down by 100 mm without swapping cylinders.
Adjustable Transfer Diverter
Tune the actuation reach on a packaging line by shortening the extend stroke on-site to match different carton widths.
Multi-Position End Stops
Set precise mechanical end positions for pallet routing, using the external stop screw to trim the 125 mm stroke to the exact required footprint.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X125-100 with the SAUJ100X125-100
Choose the 100 mm adjust window when you need to trim the extend stroke by up to 100 mm on-site. For sensing, note this non-magnet SKU lacks a switch; the SAUJ upgrade uses CMSG/DMSG/EMSG sensors instead of 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 → SAUJ100X125-100
- ✓ 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 SUJ100X125-100 FAQ
Yes, the SUJ100X125-100 is discontinued. The direct replacement is the SAUJ100X125-100, matching the 100 mm bore, 125 mm stroke, 1/2" port, and FA/LB mounting. The SAUJ also offers the SAUF built-in-valve variant and uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The 100 mm adjust window lets you trim the 125 mm extend stroke down to 25 mm on-site. The stop sets end position but is not a load lock; use an external rod lock for held loads.
