This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X100-10, 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).

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-10
The AirTAC MALJ20X100-10 is a discontinued double-acting, double-rod mini cylinder with a 20mm bore and a 100mm stroke. It features a rear adjustable stop that trims up to 10mm, giving a usable end-position window of 90-100mm. The direct replacement is the MBLJ20X100-10.
This SKU has no magnet (-S omitted), so it cannot accept a position sensor. The MALJ uses a fixed rubber bumper and threaded covers, whereas the MBLJ upgrade features a riveted rolling-packed body. The 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 MBLJ20X100-10 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 MBLJ20X100-10 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-10 Is Used
PCB drilling depth stop
Dial the rear screw to set a precise 95mm reach on a PCB drilling fixture, using the 90-100mm window to prevent drill breakthrough without adding external spacers.
Light-duty pick-and-place
Fine-tune the 100mm extension on a small electronic component pick-and-place machine, using the 20mm bore's compact footprint and 132N pull force to lift parts.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-10 with MBLJ20X100-10
Replace the MALJ20X100-10 directly with the MBLJ20X100-10, matching the 20mm bore, 100mm stroke, 10mm adjust code, G1/8 port, and PT thread. Mounting is FA or LB only (no back cover or SDB). Since this SKU lacks a magnet, no sensor fits; upgrading to the MBLJ with an -S code changes the switch family from CS1-M/DS1-M to CMSG/DMSG/EMSG. Remember the adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ20X100-10 (same bore/stroke/adjust)
- ✓ Same 90–100 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 MBLJ20X100-10 instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-10 FAQ
Yes, the MALJ20X100-10 is discontinued. The direct replacement is the MBLJ20X100-10, which matches the 20mm bore, 100mm stroke, 10mm adjust code, force, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The usable stroke window is 90-100mm (100mm stroke minus 10mm adjust code). The adjuster is a travel stop, not a lock, and this no-magnet SKU cannot take a sensor.
