This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X225-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X225-30 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 MALJ40X225-30
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-30 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 195 to 225 mm. This model is discontinued — the drop-in replacement is the MBLJ40X225-30.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-30
The AirTAC MALJ40X225-30 is a discontinued 40mm bore adjustable-stroke mini cylinder. It delivers 628N push and 528N pull at 0.5MPa, with a G1/4 port. The 30mm rear adjuster trims the end position, creating a usable 195-225mm stroke window without external stops. The drop-in replacement is the MBLJ40X225-30, matching the bore, stroke, force, and mounting.
This SKU has no magnet (-S), so it cannot take a position sensor. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ upgrade uses a riveted rolling-packed body. The Ø16mm carbon-steel rod has a 20um hard chrome plating for wear resistance.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-30 Technical Specifications

| 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 MBLJ40X225-30 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-30 Is Used
PCB Router Z-Axis Depth Stop
Dials the exact 195-225mm plunge depth for a spindle, using the 628N force to rout traces accurately while the rear stop sets the precise board clearance.
Carton Flap Folder Tensioner
Adjusts the end position to perfectly fold varying corrugated cardboard thicknesses without crushing the box, relying on the 880N force at 0.7MPa.
Pneumatic Press Pin Locator
Sets a precise 195mm retracted rest position for a pin insertion jig, preventing the 16mm rod from over-traveling and bending on misaligned parts.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-30 with MBLJ40X225-30
To replace the MALJ40X225-30, order the drop-in MBLJ40X225-30. Confirm the 40mm bore, 225mm stroke, 30mm adjust code, G1/4 port, PT thread, and FA/LB mounting (no back cover or SDB allowed). This no-S SKU lacks a magnet, so it cannot hold a sensor; if you need switches, the MBLJ uses 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 0.5MPa, while stepping up to the largest 40mm bore configuration maximizes capacity at 880N push at 0.7MPa. Because the 225mm stroke is relatively long, minimize side loads to prevent rod bending and premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ40X225-30 (same bore/stroke/adjust)
- ✓ Same 195–225 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 MBLJ40X225-30 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X225-30 FAQ
Yes, the MALJ40X225-30 is discontinued. The exact drop-in replacement is the MBLJ40X225-30, matching the 40mm bore, 225mm stroke, 30mm adjuster, G1/4 port, and FA/LB mounting. The MBLJ upgrades the body to a riveted rolling-packed design, but the force and ratings remain identical.
The 40mm bore provides 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum of 128kgf at 1.0MPa. The 30mm adjuster creates a usable stroke window of 195-225mm. This SKU has no magnet, so it cannot accept a position sensor.
