This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X120-100, with the same bore, stroke, output force, port and mounting, so it fits the same application. The MBLJ replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X120-100
The AirTAC MALJ25 Adjustable Mini Air Cylinder MALJ25X120-100 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 100 mm, giving a usable end-position window from 20 to 120 mm. This model is discontinued — the direct replacement is the MBLJ25X120-100.

About the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X120-100
The AirTAC MALJ25X120-100 is a discontinued double-acting mini cylinder with a rear travel stopper, replaced directly by the MBLJ25X120-100.
This SKU lacks a magnet, so it cannot accept a position sensor. The rear adjuster sets reach but does not hold load without live air. The original threaded covers and CS1-M/DS1-M switches are upgraded to a riveted body and CMSG/DMSG/EMSG sensors on the MBLJ.

| Replacement | MBLJ25X120-100 |
| Bore size | Ø25 mm |
| Stroke | 120 mm |
| Adjustable window | 20 – 120 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|

| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 300 mm |
The rear adjuster is a travel stop, not a lock — it sets the end position but does not hold the load without live air. No back-cover code and no SDB on adjustable-stroke. The MBLJ25X120-100 carries the same ratings.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 206 N | 206 N |
| 0.7 MPa | 289 N | — |
| Max (@1.0 MPa) | 42 kgf | |
MALJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod MAL push of the same bore. The MBLJ25X120-100 matches these values.

Where the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X120-100 Is Used
Carton Flap Tucking
Trim the rear stopper to perfectly time the tucking arm on a case erector, ensuring the 206N pull force reliably folds corrugated flaps at varying box heights without adding external stops.
Textile Fabric Press
Adjust the end position on a fabric heat-press to accommodate different material thicknesses, letting the cylinder bottom out on the rubber bumper consistently across batches.
Replacing the Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X120-100 with MBLJ25X120-100
Replace this MALJ with the direct replacement MBLJ25X120-100, confirming the 25mm bore, 120mm stroke, 100mm adjust code, G1/8 port, and PT thread. Mounting is Basic, FA, or LB only (no back cover or SDB). Since there is no -S magnet, this SKU cannot take a sensor. The adjuster is a travel stop, not a lock.
With a 120mm stroke, minimize side-load to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ25X120-100 (same bore/stroke/adjust)
- ✓ Same 20–120 mm adjustable window
- ✓ Adjuster is a stop, not a lock
- ✓ No back cover / SDB — plan an FA/LB mount
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check The rear adjuster sets the end position — it is not a load lock.
- check No back-cover / SDB on adjustable-stroke — use FA / LB.
- check Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the MBLJ25X120-100 instead of this discontinued model.
Airtac MALJ25 Adjustable Mini Air Cylinder MALJ25X120-100 FAQ
Yes, the MALJ25X120-100 is discontinued. The direct replacement is the MBLJ25X120-100, matching the 25mm bore, 120mm stroke, 100mm adjuster, and G1/8 port. The MBLJ upgrades the threaded covers to a riveted rolling-packed body.
The 100mm rear adjuster creates a usable stroke window of 20-120mm. Note that the adjuster is a travel stop, not a lock, and cannot hold a load without air pressure.
