This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X200-20-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X200-20-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 MALJ40X200-20-S

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-20-S
The AirTAC MALJ40X200-20-S is a discontinued 40mm bore, double-acting adjustable-stroke mini cylinder. It provides a usable end-position window of 180-200mm by trimming up to 20mm at the rear screw. Delivering 628N push and 528N pull force at 0.5MPa, it uses a G1/4 port and M12x1.25 rod thread. The exact drop-in replacement is the MBLJ40X200-20-S.
This SKU includes a -S magnet for CS1-M/DS1-M switches (the MBLJ upgrade uses CMSG/DMSG/EMSG). It has fixed rubber bumpers and threaded covers, whereas the MBLJ features a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-20-S Is Used
Injection Mold Ejection
Dial the 180-200mm reach to strike ejector pins precisely without over-stroking, using the 628N push force to clear molded parts.
CNC Fixture Clamping
Set exact 20mm retraction depth on the 16mm rod for raw stock clamping, preventing collision with changing tool paths.
PCB Router Stopping
Use the rear stop to fine-tune the end position, ensuring the spindle clears board edges while maintaining 528N pull force.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-20-S with MBLJ40X200-20-S
To replace this MALJ40X200-20-S, order the MBLJ40X200-20-S. Confirm the 40mm bore, 200mm stroke, 20mm adjust code, G1/4 port, PT thread, and FA/LB mounting (no back cover or SDB). Note the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster remains a travel 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 maintains the 628N push. At 200mm stroke, prevent rod bending by ensuring rigid guide alignment to avoid side loads.
Upgrade checklist
- ✓ Order the MBLJ40X200-20-S (same bore/stroke/adjust)
- ✓ Same 180–200 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 MBLJ40X200-20-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-20-S FAQ
Yes, the MALJ40X200-20-S is discontinued. The exact drop-in replacement is the MBLJ40X200-20-S, which matches the 40mm bore, 200mm stroke, 20mm adjust code, and G1/4 port. The MBLJ upgrades the body to a riveted rolling-packed design and changes the -S magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 40mm bore provides 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a max of 128kgf at 1.0MPa. The 20mm adjuster is a travel stop that lets you trim the rear position, creating a 180-200mm usable window. It is not a lock; it cannot hold a load without live air.
