This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X160-20, 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 MALJ20X160-20
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-20 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 140 to 160 mm. This model is discontinued — the direct replacement is the MBLJ20X160-20.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-20
The AirTAC MALJ20X160-20 is a discontinued double-acting, double-rod mini cylinder with a 20 mm bore and 160 mm stroke. The rear adjuster lets you trim the end position by up to 20 mm, creating a usable stroke window of 140-160 mm. The direct replacement is the MBLJ20X160-20, which matches the bore, stroke, adjust code, and G1/8 port.
This SKU has no -S magnet, so it cannot accept a position sensor. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The MALJ uses a fixed rubber bumper and threaded covers, whereas the MBLJ upgrade features a riveted rolling-packed body. If you need position sensing on the replacement, the MBLJ uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M family.

| 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 MBLJ20X160-20 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 MBLJ20X160-20 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-20 Is Used
PCB Router Depth Stop
Sets the plunge depth on a PCB depaneling router.
Label Applicator Tamp
Drives the tamp head on a bottle labeling machine. Trimming the 160 mm stroke by 20 mm compensates for varying container heights, ensuring the label wipes cleanly onto the side.
Small Part Ejector
Pushes machined fittings out of a CNC chuck. The 132 N pull force safely retracts the ejector pin, and the rear stopper lets you fine-tune the retracted position without moving the cylinder.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-20 with MBLJ20X160-20
To replace this MALJ20X160-20, order the MBLJ20X160-20. Confirm the 20 mm bore, 160 mm stroke, 20 mm adjust code, G1/8 port, and PT thread. Mounting is Basic, FA, or LB only; there is no back-cover or SDB option. Because this SKU lacks a magnet, it cannot hold a sensor; the MBLJ replacement requires CMSG/DMSG/EMSG switches for detection. The adjuster sets the end position but does not lock the load—use an external lock for holding.
At 160 mm stroke, watch for rod bending under side loads; keep the load guided to prevent rod damage.
Upgrade checklist
- ✓ Order the MBLJ20X160-20 (same bore/stroke/adjust)
- ✓ Same 140–160 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 MBLJ20X160-20 instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-20 FAQ
Yes, the MALJ20X160-20 is discontinued. The direct replacement is the MBLJ20X160-20, which keeps the 20 mm bore, 160 mm stroke, 20 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design from the MALJ's threaded covers.
The -20 adjust code provides a usable stroke window of 140-160 mm. The adjuster is a travel stop, not a lock, and this no-S SKU cannot take a position sensor.
