This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X500-75-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X500-75-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 MALJ40X500-75-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-75-S 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 425 to 500 mm. This model is discontinued — the drop-in replacement is the MBLJ40X500-75-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-75-S
The AirTAC MALJ40X500-75-S is a discontinued double-acting single-rod cylinder with a rear travel stopper. It gives a usable extension window of 425-500 mm by trimming up to 75 mm at the rear screw. At 0.5 MPa this 40 mm bore delivers 628 N push and 528 N pull force. The direct drop-in replacement is the MBLJ40X500-75-S, matching the bore, stroke, G1/4 port and 128 kgf maximum force.
Two key upgrade details apply when moving to the MBLJ. First, the MALJ uses threaded covers, whereas the MBLJ features a riveted rolling-packed body for better structural integrity. Second, the -S magnet on this MALJ works with CS1-M / DS1-M switches; the MBLJ replacement uses the newer CMSG / DMSG / EMSG sensor family. Note that the rear adjuster is a travel stop, not a lock, and end impact is softened only by a fixed rubber bumper.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-75-S Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-75-S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X500-75-S |
| Bore size | Ø40 mm |
| Stroke | 500 mm |
| Adjustable window | 425 – 500 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 MBLJ40X500-75-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 MBLJ40X500-75-S matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-75-S Is Used
Automated Door Panels
Dials the exact 425-500 mm reach to press automotive door panels without repositioning heavy fixtures, using 628 N of push force.
Pallet Wrap Stations
Trims the rear stopper to set precise film cut depths on packaging lines, preventing the 16 mm rod from overextending.
CNC Tool Changers
Fine-tunes the end position for robotic arm tool handoff, relying on the fixed rubber bumper to soften the 880 N impact at 0.7 MPa.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-75-S with MBLJ40X500-75-S
To replace this MALJ40X500-75-S, order the exact MBLJ40X500-75-S drop-in. Confirm the 40 mm bore, 500 mm stroke, 75 mm adjust code, G1/4 port, PT thread and FA/LB mounting. The -S magnet transfers over, but you must switch from CS1-M / DS1-M to CMSG / DMSG / EMSG sensors. No back cover or SDB is used. If sizing either way: step down to the 32 mm bore for 402 N push at 0.5 MPa, or step up is not applicable as 40 mm is the maximum MALJ bore. At 500 mm stroke, minimize side-load to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ40X500-75-S (same bore/stroke/adjust)
- ✓ Same 425–500 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 MBLJ40X500-75-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-75-S FAQ
Yes, the MALJ40X500-75-S is discontinued. The exact drop-in replacement is the MBLJ40X500-75-S, which matches the 40 mm bore, 500 mm stroke, 75 mm adjust code and G1/4 port. You will need to upgrade your switches from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The force output is 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. The 75 mm adjuster is a travel stop that lets you shorten the end position, creating a usable stroke window of 425-500 mm. It does not hold the load without live air.
