This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ40X175-10, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MALJ40X175-10
The AirTAC Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-10 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 165 to 175 mm. This model is discontinued — the direct replacement is the MBLJ40X175-10.

About the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-10
The AirTAC MALJ40X175-10 is a discontinued double-acting double-rod cylinder with a 10mm rear stroke adjuster, yielding a usable travel window of 165-175mm. The direct replacement is the MBLJ40X175-10, matching the 40mm bore, 175mm stroke, and G1/4 port.
This SKU lacks a magnet (-S), so it cannot accept a position sensor. Unlike the threaded covers on this MALJ, the MBLJ replacement uses a riveted rolling-packed body. The rear adjuster is a travel stop to fine-tune depth, not a lock to hold a load without live air. End impact is softened by a fixed rubber bumper, as there is no air cushion.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-10 Technical Specifications
| Model | Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-10 |

| Replacement | MBLJ40X175-10 |
| Bore size | Ø40 mm |
| Stroke | 175 mm |
| Adjustable window | 165 – 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 |
| 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 MBLJ40X175-10 carries the same ratings.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 kgf | |
MALJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod MAL push of the same bore. The MBLJ40X175-10 matches these values.

Where the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-10 Is Used
Thermoforming mold clamp
Fine-tune the 10mm rear stop to adapt plastic sheet depth on a forming press, ensuring the 16mm rod hits the exact mold height every cycle.
Woodworking router stop
Adjust the end position to set routing depth limits on an automated CNC router, leveraging the fixed rubber bumper to soften the repeated end impact.
Replacing the Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-10 with MBLJ40X175-10
To replace this MALJ40X175-10, order the MBLJ40X175-10. Confirm the 40mm bore, 175mm stroke, 10mm adjust code, G1/4 port, PT thread, and Basic/FA/LB mounting (no back cover or SDB allowed). Since this SKU has no magnet, you lose sensors entirely; if you need position detection, step up to an MBLJ-S variant which uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
For any stroke approaching 300mm, be mindful of rod bending under side loads. Remember the adjuster sets end position but does not hold load without air pressure.
Upgrade checklist
- ✓ Order the MBLJ40X175-10 (same bore/stroke/adjust)
- ✓ Same 165–175 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 MBLJ40X175-10 instead of this discontinued model.
Airtac MALJ40 Adjustable Mini Cylinder MALJ40X175-10 FAQ
Yes, the MALJ40X175-10 is discontinued. The direct replacement is the MBLJ40X175-10, matching the 40mm bore, 175mm stroke, 10mm adjuster, and G1/4 port. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The -10 code means the rear screw trims up to 10mm of travel, creating a 165-175mm usable window. It acts only as a travel stop and does not hold load without air.
