This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X160-50, 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).

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-50
The AirTAC MALJ20X160-50 is a discontinued double-acting mini cylinder with a 50 mm rear adjustable stroke stopper. It provides a usable travel window of 110-160 mm. The direct replacement is the MBLJ20X160-50, matching bore, stroke, force, and port.
This SKU lacks a magnet (-S) and cannot accept a position sensor. The original MALJ uses threaded covers and CS1-M sensors, whereas the MBLJ upgrade features a riveted rolling-packed body and CMSG switches. It uses a fixed rubber bumper, not an adjustable air cushion. The rear adjuster sets the end position but does not hold the load without live air.

| Bore size | Ø20 mm |
| Stroke | 160 mm |
| Adjustable window | 110 – 160 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 300 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 MBLJ20X160-50 carries the same ratings.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 132 N | 132 N |
| 0.7 MPa | 185 N | — |
| Max (@1.0 MPa) | 27 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 MBLJ20X160-50 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-50 Is Used
Wire Stripping Clamp
Sets a precise end position to strip insulation lengths accurately, where the fixed rubber bumper absorbs the repeated end impact.
Light Lever Actuator
Trims the reach on a small mechanical lever arm, relying on the 8 mm rod for guidance while avoiding side-load bending on the 160 mm stroke.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-50 with MBLJ20X160-50
To replace the MALJ20X160-50, install the direct replacement MBLJ20X160-50. Confirm the G1/8 port, M8x1.25 rod-end thread, PT fitting, and FA/LB mounting (no back cover or SDB). Because this SKU has no magnet, you lose sensor capability unless you upgrade to an MBLJ-S model using CMSG switches. The adjuster is a travel stop, not a lock.
If you need less force, note that 20 mm is the smallest available MALJ bore. For this 160 mm stroke, use FA or LB mounts to support the rod and prevent bending under side loads.
Upgrade checklist
- ✓ Order the MBLJ20X160-50 (same bore/stroke/adjust)
- ✓ Same 110–160 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 MBLJ20X160-50 instead of this discontinued model.
