This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X60-50, 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 MALJ20X60-50

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-50
The AirTAC MALJ20X60-50 is a discontinued double-acting, double-rod mini cylinder with a 20mm bore and 60mm stroke. A rear screw lets you trim up to 50mm, giving a usable end-position window of 10-60mm. The direct replacement is the MBLJ20X60-50, matching bore, stroke, and force.
This SKU lacks a magnet, so it cannot take a position sensor. The adjuster sets travel limits but does not hold load without live air. It uses a fixed rubber bumper, not an adjustable cushion. The original MALJ has threaded covers and a PT G1/8 port, while the MBLJ upgrade features a riveted rolling-packed body for higher structural integrity.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-50 Technical Specifications
| Model | Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-50 |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ20X60-50 |
| Bore size | Ø20 mm |
| Stroke | 60 mm |
| Adjustable window | 10 – 60 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 MBLJ20X60-50 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 MBLJ20X60-50 matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-50 Is Used
Print Head Registration
Dial the 10-60mm window to fine-tune print head contact on small format label presses without swapping physical hard stops.
PCB Edge Guide Trim
Set precise 20mm board edge clearance on SMT pick-and-place lines, using the 132N pull force to retract the guide safely.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X60-50 with MBLJ20X60-50
Replace this MALJ20X60-50 with the exact MBLJ20X60-50 direct. Confirm the 20mm bore, 60mm stroke, 50mm adjust code, PT G1/8 port, and FA/LB mounting (no back cover or SDB). Since this SKU has no -S magnet, it cannot accept a sensor; the MBLJ upgrade requires CMSG/DMSG/EMSG switches if you add one. The adjuster is a travel stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ20X60-50 (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 MBLJ20X60-50 instead of this discontinued model.
