This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X150-75-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X150-75-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 MALJ40X150-75-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-75-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 75 to 150 mm. This model is discontinued — the drop-in replacement is the MBLJ40X150-75-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-75-S
The AirTAC MALJ40X150-75-S is a discontinued adjustable-stroke mini cylinder. Its rear screw stopper trims up to 75 mm, yielding a usable 75-150 mm end-position window. As a 40 mm bore, double-acting single-rod unit, it delivers 628 N push and 528 N pull at 0.5 MPa (880 N push at 0.7 MPa). The exact drop-in replacement is the MBLJ40X150-75-S.
The MBLJ upgrade retains the G1/4 port, M12x1.25 rod thread, and 128 kgf max force, but swaps threaded covers for a riveted rolling-packed body. The -S magnet switches sensor families: legacy CS1-M / DS1-M to current CMSG / DMSG / EMSG. The adjuster is a travel stop, not a lock; it sets position without holding load. Impact is absorbed by a fixed rubber bumper, not an adjustable air cushion.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-75-S Technical Specifications

| 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 MBLJ40X150-75-S carries the same ratings.
Theoretical Output Force (Ø40mm)

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-75-S Is Used
Injection Mold Ejection
Dialing the 75-150 mm window precisely sets the ejection pin depth on a 40-ton injection molding press, using the 628 N push force to clear parts without crushing them.
PCB Conveyor Stoppers
Sets an adjustable physical dead-stop for PCB pallets on an SMT line; the fixed rubber bumper softens the 880 N impact at 0.7 MPa, protecting board edges.
Automated Press-Fit Jigs
Fine-tunes the insertion depth of threaded inserts in an aluminum housing fixture, allowing 75 mm of travel adjustment without machining new hard stops.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-75-S with MBLJ40X150-75-S
To replace the MALJ40X150-75-S, order the drop-in MBLJ40X150-75-S. Confirm the 40 mm bore, 150 mm stroke, -75 adjust code, G1/4 port, and FA/LB mounting (no back cover or SDB). Swap CS1-M/DS1-M sensors for CMSG/DMSG/EMSG. The rear adjuster is a travel stop, not a lock; use an external lock for held loads. For sizing flexibility, stepping down to the 32 mm bore yields 402 N push at 0.5 MPa, while stepping up is unavailable as 40 mm is the largest MALJ bore. Because the 150 mm stroke is substantial, prevent rod bending by minimizing side loads and guiding the payload.
Upgrade checklist
- ✓ Order the MBLJ40X150-75-S (same bore/stroke/adjust)
- ✓ Same 75–150 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 MBLJ40X150-75-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X150-75-S FAQ
Yes, the MALJ40X150-75-S is discontinued. The exact drop-in replacement is the MBLJ40X150-75-S, matching the 40 mm bore, 150 mm stroke, 75 mm adjust code, G1/4 port, and 128 kgf max force. The MBLJ upgrades the body to a riveted rolling-packed design and requires CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M switches.
The usable stroke window is 75-150 mm via the rear travel stop. It provides 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 sets the end position but does not hold the load without live air; an external lock is required for load holding.
