This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X175-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X175-100 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 MALJ40X175-100
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-100 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 100 mm, giving a usable end-position window from 75 to 175 mm. This model is discontinued — the drop-in replacement is the MBLJ40X175-100.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-100
The AirTAC MALJ40X175-100 is a discontinued 40mm bore, double-acting adjustable-stroke mini cylinder. It provides a usable stroke window of 75-175mm by trimming up to 100mm at the rear. It delivers 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBLJ40X175-100, matching bore, stroke, force, G1/4 port, and mounting.
This SKU lacks a magnet and cannot accept a position sensor. The rear adjuster is a travel stop, not a lock, so it will not hold a load without live air. The original MALJ uses threaded covers and the MBLJ upgrade features a riveted rolling-packed body. End impact is absorbed by a fixed rubber bumper, not an adjustable air cushion.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-100 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-100 |

| Adjustable window | 75 – 175 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|

| 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 MBLJ40X175-100 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 MBLJ40X175-100 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-100 Is Used
Injection Mold Breather
Dial the 75-175mm window to precisely crack an injection mold breather plate, using the 628N push force to overcome initial vacuum resistance without over-traveling.
PCB Depaneling Saw
Set the exact cut depth on a circular depaneling saw for thick PCBs, using the rear stop to fine-tune the 40mm bore reach while the fixed rubber bumper absorbs the cut impact.
Connector Pressing
Press Molex connectors into housings by adjusting the end position to 100mm, preventing damage to delicate pins by stopping the 880N @0.7MPa force at the exact insertion depth.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-100 with MBLJ40X175-100
To replace the MALJ40X175-100, order the MBLJ40X175-100. Confirm the 40mm bore, 175mm stroke, 100mm adjust code, G1/4 port, M12x1.25 rod thread, and FA/LB mounting (no back cover or SDB). Since this SKU has no -S magnet, you cannot install a sensor; the MBLJ upgrade would require CMSG/DMSG/EMSG switches if you add one. The adjuster sets the end position but does not lock the load. If sizing up, the next larger bore is unavailable in this mini series; if sizing down, the 32mm bore offers 402N push at 0.5MPa. For this 175mm stroke, minimize side-load to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ40X175-100 (same bore/stroke/adjust)
- ✓ Same 75–175 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 MBLJ40X175-100 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-100 FAQ
Yes, the MALJ40X175-100 is discontinued. The exact drop-in replacement is the MBLJ40X175-100, which matches the 40mm bore, 175mm stroke, 100mm adjust code, G1/4 port, and FA/LB mounting. The MBLJ upgrades the body to a riveted rolling-packed design.
The usable stroke window is 75-175mm via the 100mm rear adjuster. Force is 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a max of 128kgf at 1.0MPa. This specific SKU has no -S magnet, so it cannot accept a position sensor.
