This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X60-30S, 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 MALJ20X60-30S

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-30S
The AirTAC MALJ20X60-30S is a discontinued double-acting double-rod cylinder with a 20mm bore and 60mm stroke. The direct replacement is the MBLJ20X60-30S. This adjustable-stroke mini cylinder trims up to 30mm at the rear, creating a usable 30-60mm end-position window.
The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. This -S magnet SKU uses the older CS1-M / DS1-M switches, whereas the MBLJ replacement uses CMSG / DMSG / EMSG sensors. The MALJ features threaded covers and a fixed rubber bumper, while the newer MBLJ uses a riveted rolling-packed body.

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 MBLJ20X60-30S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-30S Is Used
Connector Pin Insertion
Sets a precise bottom position for pressing delicate header pins into plastic housings, preventing damage by stopping the rod short of the full 60mm stroke.
Dispenser Valve Height
Adjusts the nozzle height on an adhesive dispensing valve to maintain a consistent 0.5mm standoff gap, tweaking the reach without reprinting machine brackets.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-30S with MBLJ20X60-30S
To replace this MALJ20X60-30S with the MBLJ20X60-30S, confirm the 20mm bore, 60mm stroke, 30mm adjust code, G1/8 port, and PT thread. Mounting is FA or LB only; there is no back cover or SDB option. Remember the adjuster is a stop, not a lock. The -S magnet requires changing your CS1-M / DS1-M switches to CMSG / DMSG / EMSG on the new MBLJ.
Upgrade checklist
- ✓ Order the MBLJ20X60-30S (same bore/stroke/adjust)
- ✓ Same 30–60 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 MBLJ20X60-30S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-30S FAQ
Yes, the MALJ20X60-30S is discontinued. The direct replacement is the MBLJ20X60-30S, which matches the 20mm bore, 60mm stroke, 30mm adjust code, and G1/8 port. You must upgrade your CS1-M / DS1-M sensors to the CMSG / DMSG / EMSG family, and the threaded covers are replaced by a riveted rolling-packed body.
The usable stroke window is 30-60mm, set by trimming the rear stopper up to 30mm. The adjuster is a travel stop, not a lock, and cannot hold a load without live air.
