This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X160-30S, 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-S
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-30-S 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-S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-30-S
The AirTAC MALJ20X160-30-S is a discontinued double-acting mini cylinder with a 160 mm stroke and a 20 mm bore. It provides a usable adjustable stroke window of 130-160 mm via its 30 mm rear screw stopper. The direct replacement is the MBLJ20X160-30-S, sharing the same bore, stroke, adjust code, and G1/8 port.
This -S variant includes a magnet for CS1-M or DS1-M reed switches; the MBLJ successor upgrades this to CMSG, DMSG, or EMSG sensors. The MALJ features threaded covers and a fixed rubber bumper, whereas the MBLJ uses a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock—it sets the end position but will not hold a load without live air pressure.

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-S carries the same ratings.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |

| 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-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-30-S Is Used
Dispenser Nozzle Calibration
Fine-tune the rear stopper on an adhesive dispensing nozzle to vary the dispense height by up to 30 mm, ensuring precise fluid bead placement without changing the cylinder body.
Lightweight Parts Ejector
Eject small plastic moulded parts from a fixture using the 132 N pull force, adjusting the retract distance to accommodate varying product widths on the same assembly line.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-30-S with MBLJ20X160-30-S
To replace the MALJ20X160-30-S, order the MBLJ20X160-30-S. Confirm the 20 mm bore, 160 mm stroke, 30 mm adjust code, G1/8 PT port, and M8x1.25 rod-end thread. Mounting is limited to Basic, FA, or LB (no back-cover or SDB). Remember the adjuster is a stop, not a lock, so add an external locking valve for suspended loads. At 160 mm stroke, minimize side-load to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ20X160-30-S (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-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X160-30-S FAQ
Yes, the MALJ20X160-30-S is discontinued. The direct replacement is the MBLJ20X160-30-S, which matches the 20 mm bore, 160 mm stroke, 30 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design and changes the magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 30 mm adjuster is a travel stop that lets you shorten the end position, creating a usable stroke window of 130-160 mm. It does not hold the load without air pressure and the cylinder uses a fixed rubber bumper, not an adjustable air cushion.
