This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X65-10-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).
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X65-10-S
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X65-10-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 55 to 65 mm. This model is discontinued — the direct replacement is the MBLJ20X65-10-S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X65-10-S
The AirTAC MALJ20X65-10-S is a discontinued double-acting mini cylinder with a 20 mm bore, 65 mm stroke, and a 10 mm rear adjuster. This gives a usable extension window of 55-65 mm. The direct replacement is the MBLJ20X65-10-S, matching the bore, stroke, force, and G1/8 port.
The rear adjuster acts as a travel stop to fine-tune reach without external bolts, but it will not hold a load without live air. This -S SKU uses the older CS1-M / DS1-M reed switches, whereas the MBLJ upgrade moves to CMSG / DMSG / EMSG sensors and swaps the original threaded covers for a riveted rolling-packed body. End impact is absorbed by a fixed rubber bumper, not an adjustable air cushion.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X65-10-S Technical Specifications
| Model | Airtac MALJ20 Adjustable Mini Cylinder MALJ20X65-10-S |

| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ20X65-10-S |
| Bore size | Ø20 mm |
| Stroke | 65 mm |
| Adjustable window | 55 – 65 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 300 mm |
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 MBLJ20X65-10-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 MBLJ20X65-10-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X65-10-S Is Used
Dispenser Valve Height Trim
Fine-tune the 10 mm rear stopper on a pneumatic glue dispenser to lower the nozzle just above the target, compensating for varying syringe tip lengths.
Light Part Ejector
Use the 132 N pull force to retract a small plastic part from a mold cavity, adjusting the end position by a few millimeters to clear the extraction grippers.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X65-10-S with MBLJ20X65-10-S
To replace this MALJ20X65-10-S with the MBLJ20X65-10-S, confirm the 20 mm bore, 65 mm stroke, 10 mm adjust code, and PT G1/8 port. Mounting remains Basic, FA, or LB only—there is no back-cover or SDB option. You must also update your sensors: the MALJ -S magnet uses CS1-M / DS1-M switches, while the MBLJ uses CMSG / DMSG / EMSG. Remember the adjuster is a stop, not a lock.
Stepping down is not possible as 20 mm is the smallest bore.
Upgrade checklist
- ✓ Order the MBLJ20X65-10-S (same bore/stroke/adjust)
- ✓ Same 55–65 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 MBLJ20X65-10-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X65-10-S FAQ
Yes, the MALJ20X65-10-S is discontinued. The direct replacement is the MBLJ20X65-10-S, which matches the 20 mm bore, 65 mm stroke, 10 mm adjuster, and G1/8 port. You will need to switch from the old CS1-M / DS1-M switches to the CMSG / DMSG / EMSG sensor family, and the body changes from threaded covers to a riveted rolling-packed design.
The 10 mm rear adjuster lets you trim the end position, creating a usable stroke window of 55-65 mm. The adjuster is a travel stop only and does not lock the load without air pressure.
