This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X10-10S, 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 MALJ20X10-10-S
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X10-10-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 0 to 10 mm. This model is discontinued — the direct replacement is the MBLJ20X10-10-S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X10-10-S
The AirTAC MALJ20X10-10-S is a discontinued double-acting, double-rod mini cylinder with a 20mm bore and a 10mm rear adjustable stroke stopper. The direct replacement is the MBLJ20X10-10-S, matching the 20mm bore, 10mm stroke, G1/8 port, and FA/LB mounting. The rear adjuster lets you trim up to 10mm, creating a usable stroke window from 0 to 10mm.
The adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air. The MALJ uses a fixed rubber bumper and threaded covers, while the MBLJ upgrade features a riveted rolling-packed body. This -S magnet version works with CS1-M/DS1-M switches, whereas the MBLJ replacement uses CMSG/DMSG/EMSG sensors.

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 MBLJ20X10-10-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 MBLJ20X10-10-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X10-10-S Is Used
Micro-Dispenser Dosing
Adjust the rear stopper to fine-tune the exact shot volume of adhesive dispensed by a pneumatic micro-pump without changing hardware.
Thin-Sheet Part Ejector
Set a short 5mm kickout stroke to eject thin stamped metal sheets from a die, using the 132N pull force to retract the pin safely.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X10-10-S with MBLJ20X10-10-S
To replace this MALJ20X10-10-S, order the direct replacement MBLJ20X10-10-S. Confirm the 20mm bore, 10mm stroke, 10mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). Note the -S magnet requires changing from CS1-M/DS1-M to CMSG/DMSG/EMSG switches. The adjuster is a stop, not a lock.
For sizing, the next size down is the non-existent 12mm bore, so 20mm is the smallest available.
Upgrade checklist
- ✓ Order the MBLJ20X10-10-S (same bore/stroke/adjust)
- ✓ Same 0–10 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 MBLJ20X10-10-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X10-10-S FAQ
Yes, the MALJ20X10-10-S is discontinued. The direct replacement is the MBLJ20X10-10-S, which matches the 20mm bore, 10mm stroke, 10mm adjust code, G1/8 port, and FA/LB mounting. The MBLJ uses a riveted rolling-packed body instead of threaded covers, and its magnet uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
The 10mm adjust code allows you to trim the stroke at the rear, creating a usable window from 0 to 10mm. The adjuster is a travel stop, not a lock, and the cylinder uses a fixed rubber bumper, not an adjustable cushion.
