This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X200-75, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MALJ40X200-75
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-75 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 125 to 200 mm. This model is discontinued — the direct replacement is the MBLJ40X200-75.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-75
The AirTAC MALJ40X200-75 is a discontinued double-acting double-rod mini cylinder with a 40mm bore and a 200mm stroke. This SKU features a 75mm rear adjuster, creating a usable stroke window of 125-200mm so you can dial in the exact end position without adding external stops.
This model uses a fixed rubber bumper, meaning the adjustable stroke sets the travel endpoint but does not provide an adjustable air cushion. The rear adjuster is a travel stop, not a lock; it cannot hold a load without live air pressure. This SKU lacks a magnet (-S) and therefore cannot accept a position sensor. The original MALJ uses threaded covers and PT porting, while the MBLJ upgrade features a riveted rolling-packed body for greater structural integrity.

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 MBLJ40X200-75 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 kgf | |
MALJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod MAL push of the same bore. The MBLJ40X200-75 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-75 Is Used
PCB Conveyor Diverter
The 75mm rear adjuster fine-tunes the pusher end point on a conveyor line, using the 528N pull force to retract a deflector gate precisely without slamming the rubber bumper at full travel.
Woodworking Edge Bander
Adjusts the reach of a pressure roller arm on an edge banding machine, allowing operators to trim the 200mm stroke down to 125mm to accommodate narrower cabinet panels without swapping hardware.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-75 with MBLJ40X200-75
To replace the MALJ40X200-75, install the direct replacement MBLJ40X200-75. Confirm the 40mm bore, 200mm stroke, 75mm adjust code, G1/4 PT port, and M12x1.25 rod-end thread are retained. Mounting remains Basic, FA, or LB only (no back cover or SDB). Because this SKU lacks a magnet, there is no sensor to migrate; if you need a sensor on the new unit, you must specify an MBLJ with an -S magnet, which uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Remember the adjuster is a stop, not a lock, so external holding is needed for dead-load clamping.
Upgrade checklist
- ✓ Order the MBLJ40X200-75 (same bore/stroke/adjust)
- ✓ Same 125–200 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 MBLJ40X200-75 instead of this discontinued model.
