This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X160-10S, 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 MALJ20X160-10-S
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-10-S 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 150 to 160 mm. This model is discontinued — the direct replacement is the MBLJ20X160-10-S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-10-S
The AirTAC MALJ20X160-10-S is a discontinued double-acting, double-rod mini cylinder with a rear adjustable-stroke stopper. It provides a usable extension window of 150-160 mm by trimming up to 10 mm at the rear. The direct replacement is the MBLJ20X160-10-S, matching the 20 mm bore, G1/8 port, and mounting footprint.
The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The original MALJ uses threaded covers and a CS1-M / DS1-M magnet sensor, whereas the MBLJ upgrade features a riveted rolling-packed body and CMSG / DMSG / EMSG sensors. Impact is absorbed by a fixed rubber bumper, as there is no adjustable air cushion.

| 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 MBLJ20X160-10-S 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 MBLJ20X160-10-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-10-S Is Used
PCB Router Depth Stop
Dials the final 150-160 mm reach on a PCB depaneling router.
Dispenser Valve Timing
Trims a 10 mm window on an epoxy dispensing valve actuator. The fine-tuned end position prevents crush damage to the dispense tip during rapid double-acting cycles.
Lightweight Parts Ejector
Pushes small plastic caps out of a mold cavity. The 132 N pull force retracts the 8 mm rod quickly, while the rear stop dials the exact ejection distance.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-10-S with MBLJ20X160-10-S
To replace this MALJ20X160-10-S, order the MBLJ20X160-10-S. Confirm the 20 mm bore, 160 mm stroke, 10 mm adjust code, G1/8 PT port, and FA/LB mounting (there is no back cover or SDB option). The -S magnet changes sensor family from CS1-M / DS1-M to CMSG / DMSG / EMSG. Remember the adjuster is a stop, not a lock.
At 160 mm stroke, minimize side loads to prevent rod bending, as the fixed rubber bumper cannot absorb severe lateral impacts.
Upgrade checklist
- ✓ Order the MBLJ20X160-10-S (same bore/stroke/adjust)
- ✓ Same 150–160 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 MBLJ20X160-10-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-10-S FAQ
Yes, the MALJ20X160-10-S is discontinued. The direct replacement is the MBLJ20X160-10-S, matching the 20 mm bore, 160 mm stroke, 10 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design and changes the magnet sensor family from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The 10 mm adjust code creates a usable stroke window of 150-160 mm. The rear adjuster is a travel stop, not a load lock.
