This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X500-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X500-10 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 MALJ40X500-10
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-10 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 490 to 500 mm. This model is discontinued — the drop-in replacement is the MBLJ40X500-10.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-10
The AirTAC MALJ40X500-10 is a discontinued double-acting mini cylinder with a 10 mm rear adjustable stroke stopper. This 40 mm bore, 500 mm stroke unit trims the end position to a usable 490-500 mm window. It delivers 628 N push and 528 N pull at 0.5 MPa. The exact drop-in replacement is the MBLJ40X500-10, matching the bore, stroke, G1/4 port, and mounting footprint.
This SKU has no magnet and cannot accept a position sensor. The adjuster is a travel stop, not a lock; it cannot hold a load without live air. Two upgrade details define the MBLJ40X500-10: the older threaded covers are replaced by a riveted rolling-packed body, and the sensor family shifts from CS1-M/DS1-M to CMSG/DMSG/EMSG. Impact is absorbed by a fixed rubber bumper, as there is no adjustable air cushion.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-10 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-10 |

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 MBLJ40X500-10 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 MBLJ40X500-10 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-10 Is Used
Long-Reach Pallet Pusher
Dials the final 490-500 mm extension on a packaging line to push pallets without adding external stop blocks, using the 880 N push force at 0.7 MPa.
Conveyor Diverter Gate
Fine-tunes the actuation reach on a logistics sorting conveyor, ensuring the 16 mm rod cleanly redirects parcels at the exact 490 mm trim point.
Woodworking Feed Stop
Sets a precise depth stop on a CNC routing line, using the 10 mm rear adjustment to dial in the final material contact position without moving mechanical hard stops.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-10 with MBLJ40X500-10
Replace the MALJ40X500-10 with the drop-in MBLJ40X500-10. Confirm the 40 mm bore, 500 mm stroke, 10 mm adjust code, G1/4 port, and PT thread. Mounting is Basic, FA, or LB only (no back cover or SDB). Because this unit lacks the -S magnet, it cannot take a sensor. If you need to step down, the 32 mm bore offers 402 N push at 0.5 MPa; stepping up is not possible as 40 mm is the largest MALJ bore. At 500 mm stroke, prevent rod bending and side-load damage by guiding the load precisely. Remember the rear adjuster sets the end position but does not hold the load without air.
Upgrade checklist
- ✓ Order the MBLJ40X500-10 (same bore/stroke/adjust)
- ✓ Same 490–500 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 MBLJ40X500-10 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X500-10 FAQ
Yes, the MALJ40X500-10 is discontinued. The exact drop-in replacement is the MBLJ40X500-10, which matches the 40 mm bore, 500 mm stroke, 10 mm adjust code, and G1/4 port. The MBLJ upgrades the body to a riveted rolling-packed design and shifts the sensor options to CMSG/DMSG/EMSG switches.
The usable adjustable window is 490-500 mm. The full force figures are: 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 10 mm rear adjuster is a travel stop that sets the end position; it is not a lock and will not hold a load without live air pressure.
