This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X125-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X125-100S 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 SUJ100X125-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X125-100S 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 SAUJ100X125-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X125-100S
The AirTAC SUJ100X125-100S is a discontinued double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 25-125 mm extend out of the 125 mm nominal maximum. The 100 mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, peaking at 7068 N push at 0.9 MPa. It features a 25 mm rod, M20x1.5 rod thread, 29 mm adjustable cushions, and a 1/2" port.
This unit is replaced drop-in by the SAUJ100X125-100S, sharing the exact bore, stroke, force, port, and FA/LB mounting. The upgrade path moves legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches. For sizing, a safe working load is roughly 2356 N (60% of the 0.5 MPa push), translating to a 200 kg vertical lift with a 2:1 margin. 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 SAUJ100X125-100S 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 SAUJ100X125-100S 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 SUJ100X125-100S Is Used
Variable Depth Forming
Adjusts the extend stroke on-site for pressing or forming operations requiring precise, changeable depth limits without swapping cylinders.
Adjustable Length Sealing
Tunes the extend end-position to accommodate varying package sizes on a single line, trimming the stroke by up to 100 mm as needed.
Variable Position Diverter
Sets specific extend distances for sorting diverter arms where the required reach changes based on product dimensions.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X125-100S with the SAUJ100X125-100S
To replace this discontinued SUJ100X125-100S, order the drop-in SAUJ100X125-100S, retaining the 100 mm bore, 125 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. When sizing both ways, the neighbouring 80 mm bore provides 2513 N push at 0.5 MPa, while the 100 mm bore offers 3927 N at 0.5 MPa. Choose the 100 mm adjust window when you need wide on-site extend trimming from 125 mm down to 25 mm. Because this is an -S model, you must upgrade sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X125-100S
- ✓ 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 SUJ100X125-100S FAQ
Yes, the SUJ100X125-100S is discontinued. The exact drop-in replacement is the SAUJ100X125-100S, which shares the same profile body, 100 mm bore, 125 mm stroke, 100 mm adjust window, 1/2" port, and FA/LB mounting. You will need to upgrade the sensing from legacy CS1-B/DS1-B 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 allows you to trim the extend stroke by up to 100 mm on-site, giving a usable extend range of 25-125 mm. The stop sets end position only and is not a load lock.
