This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X200-30-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X200-30-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 MALJ40X200-30-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-30-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 170 to 200 mm. This model is discontinued — the drop-in replacement is the MBLJ40X200-30-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-30-S
The AirTAC MALJ40X200-30-S is a discontinued double-acting single-rod cylinder with a 40mm bore and 200mm stroke. The -30 adjust code provides a 170-200mm usable window, letting you dial in the rear position without external stops. It delivers 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBLJ40X200-30-S, matching the G1/4 port, force, and travel.
This SKU includes a magnet (-S) for CS1-M/DS1-M switches, whereas the MBLJ upgrade uses CMSG/DMSG/EMSG sensors. The MALJ features threaded covers and a fixed rubber bumper; the adjuster is a travel stop, not a lock. The newer MBLJ uses a riveted rolling-packed body for the same ratings.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-30-S Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-30-S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X200-30-S |
| Bore size | Ø40 mm |
| Stroke | 200 mm |
| Adjustable window | 170 – 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 MBLJ40X200-30-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 MBLJ40X200-30-S matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-30-S Is Used
PCB Router Depth Stop
Dial the 170-200mm window to set the exact Z-axis plunge on a PCB depaneling router, using the 628N push force to hold the spindle carriage firmly at the cut depth.
Aluminum Extrusion Press
Fine-tune the 200mm end position on a profile squaring press, allowing operators to trim the 30mm adjuster to compensate for varying extrusion lengths without adding external stop blocks.
Pallet Wrapper Film Clamp
Control the reach of a stretch film clamp arm on a pallet wrapper, using the 528N pull force to maintain tension while the rear stopper sets the precise release point.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-30-S with MBLJ40X200-30-S
To replace this MALJ40X200-30-S with the MBLJ40X200-30-S, confirm the 40mm bore, 200mm stroke, -30 adjust code, G1/4 port, PT thread, and FA/LB mounting (no back cover or SDB). Plan a sensor swap: the -S magnet moves from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster sets the end position but does not hold load without live air; use an external lock for suspended loads.
For sizing, step down to a 32mm bore for 402N push at 0.5MPa, or step up if 628N is insufficient. With a 200mm stroke, minimize side loads to prevent rod bending. The fixed rubber bumper absorbs end impact; adjustable stroke is not adjustable cushioning.
Upgrade checklist
- ✓ Order the MBLJ40X200-30-S (same bore/stroke/adjust)
- ✓ Same 170–200 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 MBLJ40X200-30-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X200-30-S FAQ
Yes, the MALJ40X200-30-S is discontinued. The exact drop-in replacement is the MBLJ40X200-30-S, matching the 40mm bore, 200mm stroke, 30mm adjuster, and G1/4 port. You will need to swap sensors, as the MALJ uses CS1-M/DS1-M switches while the MBLJ uses CMSG/DMSG/EMSG.
The 40mm bore provides 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum of 128kgf at 1.0MPa. The -30 code means the rear screw trims up to 30mm of travel, creating a 170-200mm usable window. This adjuster is a travel stop, not a lock, and does not hold the load without live air.
