This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X100-75-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X100-75-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 MALJ40X100-75-S
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75-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 25 to 100 mm. This model is discontinued — the drop-in replacement is the MBLJ40X100-75-S.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75-S
The AirTAC MALJ40X100-75-S is a discontinued double-acting, single-rod mini cylinder with a 40mm bore and 100mm stroke. It features a rear adjuster letting you trim up to 75mm, creating a usable end-position window of 25-100mm. It delivers 628N push and 528N pull force at 0.5 MPa. The exact drop-in replacement is the MBLJ40X100-75-S, matching the bore, stroke, adjuster, port, and mounting.
This -S SKU includes a magnet for position sensing. The older MALJ uses CS1-M or DS1-M reed switches, while the MBLJ replacement upgrades to CMSG, DMSG, or EMSG solid-state switches. The MALJ features threaded covers, whereas the newer MBLJ uses a riveted rolling-packed body. Both share a fixed rubber bumper for end-of-travel impact absorption; the adjuster is a travel stop, not a lock, and cannot hold a load without live air pressure.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75-S Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75-S |

| 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 MBLJ40X100-75-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75-S Is Used
Thermoforming Press Stops
Dialing the 25-100mm window on this 628N cylinder sets precise mold depth without swapping physical spacer blocks on the press bed.
PCB Router Z-Axis Limit
The 75mm rear adjuster acts as a travel stop to fine-tune cutting depth on a router, preventing the 16mm rod from crashing into the spoilboard.
Carton Flap Folder
Using the 880N force at 0.7 MPa, the cylinder tucks heavy corrugated flaps, with the bumper absorbing the repetitive end impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75-S with MBLJ40X100-75-S
To replace the MALJ40X100-75-S, order the exact drop-in MBLJ40X100-75-S. Confirm the 40mm bore, 100mm stroke, 75mm adjust code, G1/4 port, M12x1.25 rod-end thread, and FA/LB mounting (no back cover or SDB). If you need to step down, the 32mm bore gives 402N push at 0.5 MPa; if you need to step up, the 40mm is the largest MALJ bore available. Remember the rear adjuster sets the end position but does not lock the load without air.
Upgrade checklist
- ✓ Order the MBLJ40X100-75-S (same bore/stroke/adjust)
- ✓ Same 25–100 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 MBLJ40X100-75-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X100-75-S FAQ
Yes, the MALJ40X100-75-S is discontinued. The exact drop-in replacement is the MBLJ40X100-75-S, which matches the 40mm bore, 100mm stroke, 75mm adjuster, G1/4 port, and FA/LB mounting. The MBLJ upgrades the body to a riveted rolling-packed design and changes the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The usable stroke window is 25-100mm (100mm stroke minus the 75mm adjuster). At 0.5 MPa it provides 628N push and 528N pull force. At 0.7 MPa it provides 880N push force. The maximum force is 128 kgf at 1.0 MPa. The rear adjuster is a travel stop only and does not hold the load without air.
