This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X225-50-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X225-50-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 MALJ40X225-50-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-50-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 50 mm, giving a usable end-position window from 175 to 225 mm. This model is discontinued — the drop-in replacement is the MBLJ40X225-50-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-50-S
The AirTAC MALJ40X225-50-S is a discontinued double-acting single-rod cylinder with a 40mm bore and 225mm stroke. It features a rear screw stopper that trims up to 50mm, giving a usable extension window of 175-225mm. It delivers 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBLJ40X225-50-S, matching the bore, stroke, adjust code, and G1/4 port.
This SKU includes a magnet for CS1-M/DS1-M switches; the MBLJ upgrade shifts to CMSG/DMSG/EMSG sensors and a riveted rolling-packed body instead of the MAL threaded covers. The rear adjuster is a travel stop, not a lock, so it sets the end position without holding load. End impact is softened by a fixed rubber bumper, as there is no air cushion.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-50-S Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-50-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 MBLJ40X225-50-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-50-S Is Used
Injection Mold Ejection
Dials the exact 175-225mm ejection reach for plastic parts, using the 628N push force to clear the mold without overtravel.
PCB Router Depth Stop
Sets a precise end position on a routing axis, trimming the 50mm window to avoid cutting through the fixture base.
Aluminum Extrusion Press
Fine-tunes the 225mm clamp stroke on a 40mm bore actuator, accommodating varying profile lengths without swapping hardware.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-50-S with MBLJ40X225-50-S
To replace this MALJ40X225-50-S, order the MBLJ40X225-50-S. Confirm the 40mm bore, 225mm stroke, 50mm adjust code, G1/4 port, PT thread, and FA/LB mounting. There is no back cover or SDB option. The -S magnet means a sensor change: MAL uses CS1-M/DS1-M, while the MBLJ uses CMSG/DMSG/EMSG. The adjuster sets end position but does not hold load.
For sizing, step down to the 32mm bore for 402N push at 0.5MPa, or step up if you need more force. At 225mm, the 16mm rod handles side loads well, but keep rod-bending forces minimized.
Upgrade checklist
- ✓ Order the MBLJ40X225-50-S (same bore/stroke/adjust)
- ✓ Same 175–225 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 MBLJ40X225-50-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-50-S FAQ
Yes, the MALJ40X225-50-S is discontinued. The exact drop-in replacement is the MBLJ40X225-50-S, which matches the 40mm bore, 225mm stroke, 50mm adjust code, and G1/4 port. The MBLJ uses a riveted body and CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M switches.
The 40mm bore delivers 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum of 128kgf at 1.0MPa. The 50mm adjust code creates a usable stroke window of 175-225mm. The rear adjuster is a travel stop, not a lock, and cannot hold a load without live air.
