This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X25-10-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X25-10-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 MALJ40X25-10-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X25-10-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 15 to 25 mm. This model is discontinued — the drop-in replacement is the MBLJ40X25-10-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X25-10-S
The AirTAC MALJ40X25-10-S is a discontinued double-acting mini cylinder with a rear adjustable stroke stopper. It features a 40mm bore, a 25mm stroke, and a 10mm rear adjuster, giving a usable travel window of 15-25mm. It delivers 628N push and 528N pull force at 0.5MPa. The exact drop-in replacement is the MBLJ40X25-10-S.
This SKU includes a magnet for position sensing. The original MALJ uses the older CS1-M/DS1-M switches, while the MBLJ upgrade uses CMSG/DMSG/EMSG sensors. The MALJ has threaded covers, whereas the MBLJ features a riveted rolling-packed body. The adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air. End impact is softened by a fixed rubber bumper, meaning there is no adjustable air cushion.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X25-10-S Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X25-10-S |

| 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 MBLJ40X25-10-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X25-10-S Is Used
PCB Router Z-Axis Stop
Dial in the 15-25mm travel window to set exact router depth for milling traces, using the 628N force to hold the spindle carriage firmly against the rear stop.
Dispenser Nozzle Height Trim
Fine-tune the 10mm rear adjuster on this 25mm stroke cylinder to set precise adhesive bead height without machining new hard stops for varying PCB heights.
Small Part Crimper
Leverage the 528N pull force at 0.5MPa to crimp wire terminals, using the fixed rubber bumper to absorb the shock of the end stroke reliably.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X25-10-S with MBLJ40X25-10-S
To replace this MALJ40X25-10-S, order the MBLJ40X25-10-S. Confirm the 40mm bore, 25mm stroke, 10mm adjust code, G1/4 port, M12x1.25 rod thread, and PT port form. Mounting is Basic, FA, or LB only (no back cover or SDB). The magnet means switching from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors. The adjuster is a stop, not a lock. If sizing this bore, note the next size down is 32mm (402N push @0.5MPa), and 40mm is the largest available MALJ bore (628N push @0.5MPa).
Upgrade checklist
- ✓ Order the MBLJ40X25-10-S (same bore/stroke/adjust)
- ✓ Same 15–25 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 MBLJ40X25-10-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X25-10-S FAQ
Yes, the MALJ40X25-10-S is discontinued. The exact drop-in replacement is the MBLJ40X25-10-S, which matches the 40mm bore, 25mm stroke, 10mm adjust code, G1/4 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design and changes the magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The usable adjustable window is 15-25mm (25mm stroke minus the 10mm rear adjuster). The 40mm bore generates 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum of 128kgf at 1.0MPa. The adjuster is a travel stop, not a lock, so it will not hold a load without live air pressure.
