This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X150-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X150-10 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 MALJ40X150-10
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-10 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 140 to 150 mm. This model is discontinued — the drop-in replacement is the MBLJ40X150-10.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-10
The AirTAC MALJ40X150-10 is a discontinued double-acting, single-rod mini cylinder with a rear adjustable-stroke stopper. It delivers 628 N push and 528 N pull force at 0.5 MPa through a G1/4 port. The -10 adjust code lets you trim up to 10 mm at the rear, creating a usable stroke window of 140-150 mm without external stops. The exact drop-in replacement is the MBLJ40X150-10, matching the bore, stroke, adjust code, and force.
The rear adjuster sets the end position but is a travel stop, not a lock, so it will not hold a load without live air. This SKU lacks a magnet and cannot accept a position sensor. The original MALJ uses threaded covers and CS1-M/DS1-M switches, while the MBLJ upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. Mounting is limited to FA or LB, with no back-cover or SDB options. Impact is absorbed by a fixed rubber bumper, as there is no adjustable air cushion.

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 MBLJ40X150-10 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-10 Is Used
Printed Circuit Board Testers
Dial in the 140-150 mm reach for spring-loaded test probes, using the 628 N push force to compress contacts reliably without over-stressing the PCB.
Sheet Metal Bending Stops
Set a precise 145 mm back-gauge position for light gauge brackets, allowing operators to tweak the depth stop on the fly without swapping cylinders.
Plastic Trim Cutting
Adjust the rear stop to control the knife extension window, preventing the 880 N peak force at 0.7 MPa from cutting too deep into the extrusion profile.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-10 with MBLJ40X150-10
To replace the MALJ40X150-10 with the MBLJ40X150-10, confirm the 40 mm bore, 150 mm stroke, -10 adjust code, G1/4 port, and PT thread form. Verify your FA or LB mounting, as no back-cover or SDB is supported. Since this SKU lacks a -S magnet, it cannot hold a sensor, but if your machine used a magnetized version, note the switch family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster is a stop, not a lock, so add an external lock for held loads. If sizing either way, stepping down to the 32 mm bore yields 402 N push at 0.5 MPa, while the 40 mm bore here is the largest available in this series, providing 628 N push.
Upgrade checklist
- ✓ Order the MBLJ40X150-10 (same bore/stroke/adjust)
- ✓ Same 140–150 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 MBLJ40X150-10 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-10 FAQ
Yes, the MALJ40X150-10 is discontinued. The exact drop-in replacement is the MBLJ40X150-10, which matches the 40 mm bore, 150 mm stroke, 10 mm adjust code, G1/4 port, and 628 N push force. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The usable stroke window is 140-150 mm, set by trimming the rear stopper up to 10 mm. Force ratings 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 adjuster is a travel stop, not a lock, and impact is handled by a fixed rubber bumper.
