This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X125-100-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X125-100-S in place of this model. The MBLJ replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-100-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-100-S 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 25 to 125 mm. This model is discontinued — the drop-in replacement is the MBLJ40X125-100-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-100-S
The AirTAC MALJ40X125-100-S is a discontinued 40mm bore, double-acting adjustable-stroke mini cylinder. It features a 125mm stroke with a 100mm rear adjuster, yielding a usable end-position window of 25-125mm. The bore delivers 628N push and 528N pull at 0.5 MPa. The exact drop-in replacement is the MBLJ40X125-100-S, matching bore, stroke, port and force.
Two key upgrade facts apply to the MBLJ replacement: the MALJ uses threaded covers, while the MBLJ uses a riveted rolling-packed body; and the MALJ -S magnet uses CS1-M / DS1-M switches, whereas the MBLJ uses CMSG / DMSG / EMSG sensors. The rear adjuster is a travel stop, not a lock; it sets the end position but does not hold load without live air. End impact is softened by a fixed rubber bumper, not an adjustable air cushion.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-100-S Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-100-S |

| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 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 MBLJ40X125-100-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X125-100-S matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-100-S Is Used
PCB Router Z-Axis Depth
Dial the 25-125mm window on a PCB depaneling router to set Z-axis cutting depth, using the 628N force to plunge reliably without bottoming out.
Sheet Metal Press Brake
Fine-tune the back-gauge reach on a small press brake, trimming up to 100mm at the rear to position sheet metal accurately before bending.
Carton Folding Plow
Adjust the end position of a carton folder plow blade on a packaging line, shifting the 125mm stroke to match varying box widths without adding external stops.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-100-S with MBLJ40X125-100-S
To replace the MALJ40X125-100-S, order the exact drop-in MBLJ40X125-100-S. Confirm the 40mm bore, 125mm stroke, 100mm adjust code, G1/4 port, PT thread, and LB/FA mounting (no back cover or SDB). The -S magnet requires upgrading your CS1-M / DS1-M switches to CMSG / DMSG / EMSG sensors. Remember the adjuster is a stop, not a lock.
For sizing, stepping down to the 32mm bore yields 402N push at 0.5 MPa, while stepping up is not available as 40mm is the largest MALJ bore. At 125mm stroke, keep side-load minimized to avoid rod bending.
Upgrade checklist
- ✓ Order the MBLJ40X125-100-S (same bore/stroke/adjust)
- ✓ Same 25–125 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 MBLJ40X125-100-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-100-S FAQ
Yes, the MALJ40X125-100-S is discontinued. The exact drop-in replacement is the MBLJ40X125-100-S, matching the 40mm bore, 125mm stroke, 100mm adjust code, G1/4 port and LB/FA mounting. You must upgrade your switches from CS1-M / DS1-M to CMSG / DMSG / EMSG sensors.
The 40mm bore provides 628N push and 528N pull at 0.5 MPa, 880N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. The 100mm adjuster is a travel stop that lets you trim the 125mm stroke down to a 25mm minimum, creating a 25-125mm usable window. It does not hold load without live air.
