This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X130-30-S, 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 MALJ20X130-30-S
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X130-30-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 100 to 130 mm. This model is discontinued — the direct replacement is the MBLJ20X130-30-S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X130-30-S
The AirTAC MALJ20X130-30-S is a discontinued adjustable-stroke mini cylinder. It gives a usable 100-130 mm stroke window by trimming up to 30 mm at the rear screw. The direct replacement is the MBLJ20X130-30-S, matching the 20 mm bore, 130 mm stroke, G1/8 port, and force.
The rear adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air. The fixed rubber bumper softens end impact, but there is no adjustable air cushion. For sensing, the -S magnet uses older CS1-M/DS1-M switches, while the MBLJ upgrades to CMSG/DMSG/EMSG. The MALJ has threaded covers, 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 does not hold the load without live air. No back-cover code and no SDB on adjustable-stroke. The MBLJ20X130-30-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 MBLJ20X130-30-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X130-30-S Is Used
Connector Insertion Depth Setter
Trim the rear 30 mm stopper to set exact pin insertion depth on an electronics assembly line, preventing over-stroke damage to delicate housings.
Small Parts Ejector Arm
Fine-tune the ejection stroke window on a pick-and-place gantry so the 8 mm rod taps parts cleanly into chutes without needing external physical stops.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X130-30-S with MBLJ20X130-30-S
To replace the MALJ20X130-30-S, order the direct replacement MBLJ20X130-30-S. Confirm the 20 mm bore, 130 mm stroke, 30 mm adjust code, PT G1/8 port, and M8x1.25 rod thread. Mounting is Basic, FA, or LB only (no back cover or SDB). The -S magnet requires switching from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors. The adjuster is a stop, not a lock.
At 130 mm stroke, the 8 mm rod is prone to bending under side loads—keep the load perfectly axial to avoid premature seal wear.
Upgrade checklist
- ✓ Order the MBLJ20X130-30-S (same bore/stroke/adjust)
- ✓ Same 100–130 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 MBLJ20X130-30-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X130-30-S FAQ
Yes, the MALJ20X130-30-S is discontinued. The direct replacement is the MBLJ20X130-30-S, matching the 20 mm bore, 130 mm stroke, 30 mm adjust code, G1/8 port, and force. You will need to upgrade your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The -30 adjust code lets you trim the rear stopper for a usable 100-130 mm stroke window. Remember the adjuster is a travel stop, not a lock; it cannot hold a load without live air.
