This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X200-50, 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 MALJ40X200-50
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-50 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 150 to 200 mm. This model is discontinued — the direct replacement is the MBLJ40X200-50.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-50
The AirTAC MALJ40X200-50 is a discontinued 40mm bore, double-acting double-rod mini cylinder with a 50mm rear adjustable stroke stopper. This yields a usable travel window of 150-200mm. The direct replacement is the MBLJ40X200-50, matching the bore, stroke, force, G1/4 port, and mounting.
This SKU lacks a magnet (-S) and 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. Unlike the older threaded covers on this MALJ, the MBLJ replacement features a riveted rolling-packed body. Impact is absorbed solely by a fixed rubber bumper, as there is no adjustable air cushion.

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 MBLJ40X200-50 carries the same ratings.
Theoretical Output Force (Ø40mm)

| 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 MBLJ40X200-50 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-50 Is Used
Injection Mold Ejector Pin
Trim the stroke by up to 50mm to time the ejection of plastic parts from a mold cavity, preventing the 16mm rod from over-traveling and marking the parting line.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-50 with MBLJ40X200-50
To replace the MALJ40X200-50, order the MBLJ40X200-50. Confirm the 40mm bore, 200mm stroke, 50mm adjust code, G1/4 port, and M12x1.25 rod-end thread. Mounting is Basic, FA, or LB only (no back cover or SDB). Since this SKU has no -S magnet, it cannot accept a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if sensing is needed. The adjuster is a stop, not a lock.
With a 200mm stroke, minimize side-load on the 16mm rod to prevent bending and premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ40X200-50 (same bore/stroke/adjust)
- ✓ Same 150–200 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 MBLJ40X200-50 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-50 FAQ
Yes, the MALJ40X200-50 is discontinued. The direct replacement is the MBLJ40X200-50, which matches the 40mm bore, 200mm stroke, 50mm adjuster, G1/4 port, and 128kgf max force. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors if a magnet is added.
The 50mm adjuster code lets you trim the rear travel stop, creating a usable stroke window of 150-200mm. The adjuster is a travel stop only, not a lock, and will not hold a load without continuous air pressure.
