This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X125-10S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X125-10S in place of this model. 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 SUJ100X125-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X125-10S 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 drop-in replacement is the SAUJ100X125-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X125-10S
The AirTAC SUJ100X125-10S is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 115-125 mm extend out of the 125 mm nominal maximum. The 100 mm bore generates 3927 N push and 3681 N pull at 0.5 MPa, rising to 7068 N push at 0.9 MPa, via a 1/2" port and Ø25 mm rod. This compact extruded barrel is shorter than an ISO 15552 cylinder of the same bore.
Because the SUJ line is end-of-life, the exact drop-in replacement is the SAUJ100X125-10S, which preserves the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade adopts current CMSG/DMSG/EMSG sensors in place of the legacy CS1-B/DS1-B switches used here, and the SAU family adds an SAUF built-in-valve variant the SU line lacked. For sizing, the 3927 N push at 0.5 MPa implies a safe working load around 2356 N (60%), or a 200 kg vertical lift with a 2:1 margin. Note the stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X125-10S 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 SAUJ100X125-10S produces the same force from the same bore — a true drop-in on output. 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 SUJ100X125-10S Is Used
Press Fit Calibration
Dialing in a precise 115-125 mm extend for seating bearings, where the 10 mm stop screw window absorbs mechanical tolerance stack-up without reprogramming the PLC.
Variable Depth Sealing
Adjusting the extend end position on-site to accommodate different carton depths or flap heights in end-of-line packaging machinery.
Transfer Stop Positioning
Fine-tuning the extend stop point for product diverters or lane guides on a conveyor to handle slight product size variations.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X125-10S with the SAUJ100X125-10S
To replace the discontinued SUJ100X125-10S, specify the drop-in SAUJ100X125-10S, which matches the 100 mm bore, 125 mm stroke, 10 mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, the neighboring 80 mm bore yields 2513 N push at 0.5 MPa, while the 100 mm bore provides 3927 N push at 0.5 MPa (7068 N at 0.9 MPa). Choose the 10 mm adjust window if you need precise 115-125 mm extend tuning; for larger trims, select a bigger adjust figure. If your stroke is 300 mm or longer, verify side-load limits to prevent rod deflection. The -S suffix means a piston magnet is present; you must upgrade from legacy CS1-B/DS1-B sensors to CMSG/DMSG/EMSG switches on the SAUJ. Mounting compatibility is strictly with the AirTAC SC series.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X125-10S
- ✓ 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 SUJ100X125-10S FAQ
Yes, the SUJ100X125-10S is discontinued. The exact drop-in replacement is the SAUJ100X125-10S, which preserves the 100 mm bore, 125 mm stroke, 10 mm adjust window, 1/2" port, and FA/LB mounting. You simply upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The 100 mm bore provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N push at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The external stop screw provides a 10 mm adjust window, allowing you to shorten the 125 mm nominal extend stroke down to 115 mm on-site. The stop sets end position only and does not lock the load.
