This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X175-50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X175-50 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 MALJ40X175-50
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-50 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 125 to 175 mm. This model is discontinued — the drop-in replacement is the MBLJ40X175-50.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-50
The AirTAC MALJ40X175-50 is a discontinued double-acting, single-rod adjustable-stroke cylinder. It trims up to 50 mm at the rear, giving a usable end-position window of 125-175 mm. The 40 mm bore delivers 628 N push and 528 N pull at 0.5 MPa. The exact drop-in replacement is the MBLJ40X175-50, matching bore, stroke, force, G1/4 port, and mounting.
This unit has no magnet (-S), so it cannot take a position sensor. The rear adjuster sets travel, acting as a stop, not a lock. It cannot hold a load without live air. The original MALJ uses threaded covers and a fixed rubber bumper. The MBLJ upgrade shifts to a riveted rolling-packed body. If you need a held load, add an external locking mechanism.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-50 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-50 |

| Adjustable window | 125 – 175 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 |

| 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 MBLJ40X175-50 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 MBLJ40X175-50 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-50 Is Used
Printed Circuit Board Tester
Dial the 125-175 mm reach to test varied PCB stack heights. The 628 N push force secures test fixtures without crushing delicate components.
Packaging Flap Folder
Fine-tune the folding depth on carton sealing machines. The rear stopper sets the exact 150 mm end position for consistent cardboard creases.
Pneumatic Press Brake
Adjust the stroke window for bending thin sheet metal. The fixed rubber bumper absorbs the 880 N impact force at 0.7 MPa, protecting the tooling.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-50 with MBLJ40X175-50
To replace the MALJ40X175-50, order the MBLJ40X175-50. Confirm your bore, 175 mm stroke, 50 mm adjust code, G1/4 port, PT thread, and FA/LB mounting (no back cover or SDB). Since this SKU lacks the -S magnet, it cannot accept a sensor. The MBLJ upgrade requires CMSG, DMSG, or EMSG switches if you add one.
For sizing flexibility, step down to the 32 mm bore (402 N push at 0.5 MPa) for lighter loads, or step up if you need more force. The 40 mm bore is the largest in this mini series, pushing 880 N at 0.7 MPa. At 175 mm stroke, mind rod side-load; use proper guide rails to prevent bending the 16 mm rod. Remember, the adjuster is a travel stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ40X175-50 (same bore/stroke/adjust)
- ✓ Same 125–175 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 MBLJ40X175-50 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-50 FAQ
Yes, the MALJ40X175-50 is discontinued. The exact drop-in replacement is the MBLJ40X175-50, matching the 40 mm bore, 175 mm stroke, 50 mm adjust code, force, and G1/4 port. The MBLJ upgrades the body to a riveted rolling-packed design.
The 40 mm bore delivers 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a max of 128 kgf at 1.0 MPa. The 50 mm adjuster is a travel stop that shortens the end position, creating a usable 125-175 mm window. It does not hold the load without live air.
