This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X200-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X200-40 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 MALJ40X200-40
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-40 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 40 mm, giving a usable end-position window from 160 to 200 mm. This model is discontinued — the drop-in replacement is the MBLJ40X200-40.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-40
The AirTAC MALJ40X200-40 is a discontinued double-acting mini cylinder with a 40 mm bore and 200 mm stroke. It provides a usable stroke window of 160-200 mm by trimming up to 40 mm at the rear screw. It delivers 628 N push and 528 N pull force at 0.5 MPa. The direct drop-in replacement is the MBLJ40X200-40, matching the bore, stroke, adjust code, and G1/4 port.
This SKU lacks the -S magnet, so it cannot take a position sensor. The original MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body. Remember the rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air.

| 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 MBLJ40X200-40 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 MBLJ40X200-40 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-40 Is Used
PCB Router Z-Axis
Dials the exact 160-200 mm cutting depth on a printed circuit board routing spindle, using the 628 N push force to plunge the tool consistently without bottoming out.
Aluminum Extrusion Press
Fine-tunes the end position of a 40 mm clamping face in an extrusion cut-off saw, absorbing impact via the fixed rubber bumper while trimming the 40 mm window.
Wooden Door Assembly Jig
Adjusts the reach of a hold-down clamp during cabinet door gluing, relying on the 528 N pull force to pull the frame square without adding external stops.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-40 with MBLJ40X200-40
To replace this MALJ40X200-40 with the MBLJ40X200-40, confirm the 40 mm bore, 200 mm stroke, 40 mm adjust code, G1/4 port, and PT thread. Mounting is Basic, FA, or LB only (no back-cover or SDB). Because this SKU has no -S magnet, it cannot accept a sensor; if you need sensing, the MBLJ upgrade requires CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. The adjuster is a stop, not a lock.
For sizing, stepping down to a 32 mm bore drops thrust to 402 N push at 0.5 MPa. Stepping up is not possible as 40 mm is the largest MALJ bore. At 200 mm stroke, minimize side-load on the 16 mm rod to prevent rod-bending and premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ40X200-40 (same bore/stroke/adjust)
- ✓ Same 160–200 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 MBLJ40X200-40 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-40 FAQ
Yes, the MALJ40X200-40 is discontinued. The exact drop-in replacement is the MBLJ40X200-40, which matches the 40 mm bore, 200 mm stroke, 40 mm adjust code, and G1/4 port. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The force ratings are 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. The -40 adjust code means you can trim the rear travel by up to 40 mm, creating a usable stroke window of 160-200 mm. The adjuster is a travel stop, not a lock, and cannot hold a load without air pressure.
