This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X200-50, 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 MALJ20X200-50
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-50 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 150 to 200 mm. This model is discontinued — the direct replacement is the MBLJ20X200-50.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-50
The AirTAC MALJ20X200-50 is a discontinued adjustable-stroke mini cylinder. The -50 adjust code lets you trim the rear travel up to 50 mm, creating a usable stroke window of 150-200 mm. The direct replacement is the MBLJ20X200-50.
This 20 mm bore uses a G1/8 port and an 8 mm carbon-steel rod with a 20 um hard chrome plating. 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 SKU lacks a magnet (-S), so it cannot accept a position sensor. The original MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-50 Technical Specifications
| Model | Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-50 |

| Stroke | 200 mm |
| Adjustable window | 150 – 200 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|

| 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 MBLJ20X200-50 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 MBLJ20X200-50 matches these values.

| S | Optional magnet for a CS1-M / DS1-M sensor (MBLJ uses CMSG/DMSG/EMSG). |
Replacement: MALJ → MBLJ. No back-cover (CA/U/CM) and no SDB. Mounting: FA / LB.
Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-50 Is Used
Print Head Registration
Dial in the 150-200 mm reach on a screen-printing press to lower the head precisely without adding external mechanical stops.
Pick-and-Place Tweak
Fine-tune the end position on a small electronic component placement arm, trimming up to 50 mm to adapt to varying board thicknesses.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-50 with MBLJ20X200-50
To replace this MALJ20X200-50 with the MBLJ20X200-50, confirm the 20 mm bore, 200 mm stroke, 50 mm adjust code, G1/8 port, and PT thread. Mounting is FA or LB only (no back cover or SDB). Because this SKU has no -S magnet, it cannot take a sensor; the MBLJ upgrade would use CMSG/DMSG/EMSG switches if you add a magnet. If you need to size either way: stepping down to a 16 mm bore (if available) lowers force, while stepping up to a 25 mm bore increases push force to 245 N at 0.5 MPa. At 200 mm stroke, minimize side-load to prevent rod bending.
Upgrade checklist
- ✓ Order the MBLJ20X200-50 (same bore/stroke/adjust)
- ✓ Same 150–200 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 MBLJ20X200-50 instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-50 FAQ
Yes, the MALJ20X200-50 is discontinued. The direct replacement is the MBLJ20X200-50, which shares the same 20 mm bore, 200 mm stroke, 50 mm adjust code, G1/8 port, and FA/LB mounting. The MBLJ upgrades the body to a riveted rolling-packed design, replacing the original threaded covers.
The usable adjustable window is 150-200 mm (200 mm stroke minus the 50 mm adjust code). The adjuster is a travel stop, not a lock, and this no-magnet SKU cannot accept a sensor.
