This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X200-40-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X200-40-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 MALJ40X200-40-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-40-S 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-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-40-S
The AirTAC MALJ40X200-40-S is a discontinued double-acting, single-rod mini cylinder with a 40mm bore and 200mm stroke. The -40 adjust code provides a 40mm rear travel stop, giving a usable end-position window of 160-200mm. It delivers 628N push and 528N pull force at 0.5 MPa, and uses a G1/4 port with an M12x1.25 rod-end thread. The exact drop-in replacement is the MBLJ40X200-40-S, matching bore, stroke, force, and mounting.
This -S magnet model uses the older CS1-M / DS1-M switches, which upgrade to CMSG / DMSG / EMSG sensors on the MBLJ. The MALJ features threaded covers, while the MBLJ replacement uses a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock, and the fixed rubber bumper softens end impact without holding the load pneumatically. Mounting is FA or LB only, with no back-cover or SDB options.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-40-S Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-40-S |

| Bore size | Ø40 mm |
| Stroke | 200 mm |
| Adjustable window | 160 – 200 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| 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-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|

| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X200-40-S matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-40-S Is Used
Packaging flute depth stops
Dial the 160-200mm reach on a carton folder to set precise folding flap depth, using the 880N push at 0.7 MPa to crease heavy corrugated board without changing hardware.
Injection mold ejector timing
Trim the 40mm return stroke on a plastic mold ejector to sync part release with the robot picker, preventing over-travel and marking on hot parts.
Wood router depth limit
Set a repeatable 160mm retracted position on an automated wood routing gantry, letting the 628N force hold the tool clear of the table during rapid indexing.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-40-S with MBLJ40X200-40-S
To replace the MALJ40X200-40-S, order the MBLJ40X200-40-S. Confirm the 40mm bore, 200mm stroke, -40 adjust code, G1/4 port, PT thread, and FA/LB mounting. The -S magnet means your CS1-M / DS1-M switches must change to the CMSG / DMSG / EMSG family. The adjuster sets end position but does not hold load without live air; add an external lock for held loads. If sizing differently, the 32mm bore neighbour gives 402N push at 0.5 MPa, while no larger standard MALJ bore exists. At 200mm stroke, rod sag can invite side-load wear; ensure rigid front mounting to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ40X200-40-S (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-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-40-S FAQ
Yes, the MALJ40X200-40-S is discontinued. The exact drop-in replacement is the MBLJ40X200-40-S, matching the 40mm bore, 200mm stroke, -40 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 force ratings are 628N push and 528N pull at 0.5 MPa, 880N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. The -40 adjuster is a travel stop that lets you trim the rear end position by up to 40mm, creating a usable stroke window of 160-200mm. It does not lock the load without live air.
