This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X150-50-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X150-50-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 MALJ40X150-50-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-50-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 50 mm, giving a usable end-position window from 100 to 150 mm. This model is discontinued — the drop-in replacement is the MBLJ40X150-50-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-50-S
The AirTAC MALJ40X150-50-S is a discontinued double-acting single-rod cylinder with a 40mm bore and 150mm stroke. It features a rear travel stop that lets you trim up to 50mm, creating a usable 100-150mm end-position window without external stops. It delivers 628N push and 528N pull force at 0.5 MPa. The exact drop-in replacement is the MBLJ40X150-50-S.
This mini cylinder uses a fixed rubber bumper, not an adjustable air cushion. The rear adjuster sets the end position but does not hold the load without live air. For your magnet (-S) upgrade, the older CS1-M/DS1-M switches move to CMSG/DMSG/EMSG sensors. The MALJ uses threaded covers, while the MBLJ replacement features a riveted rolling-packed body.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-50-S Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-50-S |

| 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 MBLJ40X150-50-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-50-S Is Used
Packaging Carton Flappers
Dials the exact 100-150mm reach to tuck flaps on varying box sizes, using 628N push force to cleanly fold heavy corrugated cardboard without crushing the carton.
CNC Lathe Bar Feeders
Fine-tunes the retracted stop depth to push raw bar stock into the collet, letting operators trim the 50mm window to match exact spindle insertion limits.
Injection Mold Ejection
Sets a precise ejection reach for plastic parts, preventing over-travel and marking by stopping the rod short of the full 150mm stroke.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-50-S with MBLJ40X150-50-S
To replace this MALJ40X150-50-S, order the MBLJ40X150-50-S. Confirm the 40mm bore, 150mm stroke, 50mm adjust code, G1/4 port, PT threads, and FA/LB mounting (no back cover or SDB). The -S magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster is a travel stop, not a lock.
For sizing flexibility, stepping down to the 32mm bore yields 402N push force, while stepping up to the next size is unavailable as 40mm is the largest MALJ bore. At 150mm stroke, prevent rod bending by ensuring rigid guidance and minimizing side loads.
Upgrade checklist
- ✓ Order the MBLJ40X150-50-S (same bore/stroke/adjust)
- ✓ Same 100–150 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 MBLJ40X150-50-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-50-S FAQ
Yes, the MALJ40X150-50-S is discontinued. The exact drop-in replacement is the MBLJ40X150-50-S, which matches the 40mm bore, 150mm stroke, 50mm adjust code, G1/4 port, and FA/LB mounting. You must upgrade your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG switches.
The -50 adjust code lets you trim up to 50mm at the rear, creating a usable 100-150mm stroke window. The full force figures 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 adjuster is a travel stop, not a lock.
