This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X125-75-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X125-75-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).

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-75-S
The AirTAC MALJ40X125-75-S is a discontinued double-acting single-rod cylinder with a 40mm bore and 125mm stroke. A rear screw trims up to 75mm, giving a usable end-position window of 50-125mm. It delivers 628N push and 528N pull at 0.5MPa. The exact drop-in replacement is the MBLJ40X125-75-S.
This -S SKU uses a CS1-M/DS1-M magnet; the MBLJ upgrade shifts to CMSG/DMSG/EMSG sensors and swaps threaded covers for a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock. It uses a fixed rubber bumper, not an adjustable cushion. With a 16mm carbon-steel rod and G1/4 port, it handles heavy work without external stops.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-75-S Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-75-S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ40X125-75-S |
| Bore size | Ø40 mm |
| Stroke | 125 mm |
| Adjustable window | 50 – 125 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| 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 MBLJ40X125-75-S carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X125-75-S matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-75-S Is Used
Stamping press feed
Dial the 50-125mm window to push blanks into a die. The 880N force at 0.7MPa drives heavy steel reliably.
Pallet wrapper height stop
Set the exact film carriage height without external stops. The 75mm rear trim adapts to various pallet loads.
Wood router clamping jig
Secure hardwood parts for routing. The fixed rubber bumper softens the 628N impact at the end of stroke.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-75-S with MBLJ40X125-75-S
To replace this MALJ40X125-75-S, order the MBLJ40X125-75-S. Confirm the 40mm bore, 125mm stroke, 75mm adjust code, G1/4 port, PT thread, and FA/LB mounting (no back cover or SDB). The -S magnet changes the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster sets the end position but does not hold load without live air.
For sizing, step down to the 32mm bore (402N push at 0.5MPa) if your load is lighter, or step up if you need more force. At 125mm stroke, side-load and rod-bending risks are moderate; ensure rigid mounting to guide the load.
Upgrade checklist
- ✓ Order the MBLJ40X125-75-S (same bore/stroke/adjust)
- ✓ Same 50–125 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 MBLJ40X125-75-S instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X125-75-S FAQ
Yes, the MALJ40X125-75-S is discontinued. The exact drop-in replacement is the MBLJ40X125-75-S, matching the 40mm bore, 125mm stroke, 75mm adjust code, and G1/4 port. The MBLJ uses a riveted body and CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M.
The 40mm bore delivers 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a max of 128kgf at 1.0MPa. The 75mm adjuster creates a usable stroke window of 50-125mm. The adjuster is a travel stop, not a lock.
