This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X120-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X120-100 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 SUJ100X120-100
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X120-100 is a double-acting profile-type standard cylinder with a Ø100mm bore and 120mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X120-100, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X120-100
The AirTAC SUJ100X120-100 is a double-acting single-rod profile cylinder with an adjustable stroke, allowing you to trim the extend stroke by up to 100 mm on-site. With a nominal 120 mm stroke, the usable extend range is 20-120 mm. This discontinued 100 mm bore model delivers a push force of 3927 N and pull of 3681 N at 0.5 MPa, utilizing a 1/2 inch port and M20x1.5 rod thread. The drop-in replacement is the SAUJ100X120-100, matching the bore, stroke, force, and SC-series mounting.
The external stop screw sets the end position but is not a load lock; an external rod lock is required for held loads. At 0.5 MPa, the safe working load is approximately 2356 N (60% of push), yielding a vertical lift capacity of about 200 kg with a 2:1 margin. The SAUJ upgrade transitions sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors. This SKU lacks a magnet and cannot accept switches.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X120-100 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 SAUJ100X120-100 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.
Model Code: Airtac SUJ Adjustable Cylinder SUJ100X120-100
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×120 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUJ100X120-100 Is Used
Variable Depth Pressing
Allows operators to fine-tune the extend end position on-site for pressing assemblies to varying depths without changing the cylinder.
Adjustable Diverter Stroke
Accommodates changing package sizes on a line by trimming the extend stroke by up to 100 mm to hit different divert points.
Custom Format Stops
Provides adaptable end-stop positioning for pallets or materials of fluctuating lengths in compact profile machinery.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X120-100 with the SAUJ100X120-100
To replace the discontinued SUJ100X120-100, use the SAUJ100X120-100 drop-in, retaining the 1/2 inch port, 7068 N push force at 0.9 MPa, and FA/LB mounting. For sizing both ways, the neighboring 80 mm bore provides 2513 N push at 0.5 MPa, while the 100 mm bore offers 3927 N. Choose the 100 mm adjust window when you need maximum field flexibility to shorten the extend stroke from 120 mm down to 20 mm. Because this specific SKU has no magnet, it cannot accept sensors, unlike the -S variant which uses CMSG/DMSG/EMSG on the SAUJ. For strokes of 300 mm or more, verify side-load limits to prevent rod bearing wear.
Replacement checklist

- ✓ 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
