This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X160-30, 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 MALJ20 Adjustable Mini Cylinder MALJ20X160-30
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-30 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 130 to 160 mm. This model is discontinued — the direct replacement is the MBLJ20X160-30.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-30
The AirTAC MALJ20X160-30 is a discontinued adjustable-stroke mini cylinder. The direct replacement is the MBLJ20X160-30, matching the 20mm bore, 160mm stroke, G1/8 port, and 30mm adjust code. This double-acting double rod unit has a usable stroke window of 130-160mm.
The rear screw trims up to 30mm of travel without external stops. This adjuster is a travel stop, not a lock; it cannot hold a load without live air. This SKU lacks a magnet (-S), so it cannot accept a position sensor. The original MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body.

| 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 MBLJ20X160-30 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 MBLJ20X160-30 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-30 Is Used
Wire Stripping Gauge
Adjust the rear stop on an automated wire processing line to hit varying strip lengths, letting the 8mm rod retract cleanly without reprogramming the PLC.
Small Parts Ejector
Fine-tune the ejection reach on a pick-and-place fixture for electronic connectors, trimming 30mm off the end position to avoid crashing into downstream tooling.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-30 with MBLJ20X160-30
Replace this MALJ20X160-30 directly with the MBLJ20X160-30. Confirm the 20mm bore, 160mm stroke, 30mm adjust code, G1/8 port, PT threads, and FA/LB mounting (no back cover or SDB). Because this SKU has no -S magnet, it cannot take a sensor; the MBLJ upgrade without -S is identical, but adding an -S changes the switch family from CS1-M/DS1-M to CMSG/DMSG/EMSG. The rear adjuster sets the end position but does not hold load without air; use an external lock for held loads.
At 160mm stroke, watch rod bending under side-load—the 8mm rod needs careful alignment to prevent premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ20X160-30 (same bore/stroke/adjust)
- ✓ Same 130–160 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 MBLJ20X160-30 instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-30 FAQ
Yes, the MALJ20X160-30 is discontinued. The direct replacement is the MBLJ20X160-30, which matches the 20mm bore, 160mm stroke, 30mm adjust code, G1/8 port, and force. The MBLJ upgrades the construction with a riveted rolling-packed body instead of threaded covers.
Because this specific SKU lacks the -S magnet code, it cannot accept a position sensor; the CS1-M/DS1-M switches only fit the -S version.
