This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X60-50S, 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 MALJ20X60-50S
The AirTAC MALJ20 Adjustable Mini Cylinder MALJ20X60-50S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 50 mm, giving a usable end-position window from 10 to 60 mm. This model is discontinued — the direct replacement is the MBLJ20X60-50S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-50S
The AirTAC MALJ20X60-50S is a discontinued double-acting mini cylinder with a 20 mm bore and 60 mm stroke. It features a 50 mm rear adjuster, creating a usable end-position window from 10 to 60 mm. The direct replacement is the MBLJ20X60-50S, matching bore, stroke, force, and G1/8 port.
This SKU includes a magnet (-S) for CS1-M or DS1-M switches. The MBLJ upgrade shifts to CMSG/DMSG/EMSG sensors and replaces the original threaded covers with a riveted rolling-packed body. The adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air. A fixed rubber bumper softens end impact.

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 MBLJ20X60-50S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-50S Is Used
Carton Flap Folding
Fine-tune the rear stop to 45 mm so the 132 N pull force tucks corrugated cardboard flaps precisely under a sealing bar without tearing the glue tabs.
Micro-Clamp Depth Setting
Set the 50 mm adjuster to lock a 35 mm reach for clamping small plastic injection moulds, preventing the rod from over-traveling and deforming the parting line.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-50S with MBLJ20X60-50S
Replace the MALJ20X60-50S directly with the MBLJ20X60-50S. Confirm the 20 mm bore, 60 mm stroke, 50 mm adjust code, G1/8 PT port, M8x1.25 rod thread, and FA/LB mounting. Note that this old -S magnet requires CS1-M/DS1-M switches, while the MBLJ uses CMSG/DMSG/EMSG. The rear adjuster is a stop, not a lock.
This cylinder has no back cover or SDB; it uses a fixed rubber bumper, not an adjustable cushion.
Upgrade checklist
- ✓ Order the MBLJ20X60-50S (same bore/stroke/adjust)
- ✓ Same 10–60 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 MBLJ20X60-50S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-50S FAQ
Yes, the MALJ20X60-50S is discontinued. The direct replacement is the MBLJ20X60-50S, offering the same 20 mm bore, 60 mm stroke, 50 mm adjust code, force, and G1/8 port. You only need to update your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The usable stroke window is 10-60 mm. The rear adjuster is a travel stop, not a lock, so it cannot hold a load without live air.
