This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X35-20-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).

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X35-20-S
The AirTAC MALJ20X35-20-S is a discontinued double-acting mini cylinder with a 20 mm bore and a 35 mm stroke. It features a rear adjuster that trims up to 20 mm, giving a usable end-position window of 15-35 mm. The direct replacement is the MBLJ20X35-20-S, matching the bore, stroke, G1/8 port, and FA/LB mounting.
This -S SKU includes a magnet for CS1-M / DS1-M switches; the MBLJ upgrade moves to CMSG / DMSG / EMSG sensors. The MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ uses a riveted rolling-packed body. The adjuster is a travel stop, not a lock, so it sets the end position without holding load without live air.

Theoretical Output Force (Ø20mm)

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 MBLJ20X35-20-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X35-20-S Is Used
Dispenser Nozzle Height

Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X35-20-S with MBLJ20X35-20-S
Replace this MALJ20X35-20-S with the exact direct replacement MBLJ20X35-20-S. Confirm the 20 mm bore, 35 mm stroke, 20 mm adjust code, PT G1/8 port, M8x1.25 rod thread, and FA/LB mounting (no back cover or SDB). The -S magnet means a sensor family change from CS1-M / DS1-M to CMSG / DMSG / EMSG. Remember the adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ20X35-20-S (same bore/stroke/adjust)
- ✓ Same 15–35 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 MBLJ20X35-20-S instead of this discontinued model.
