This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X100-10S, 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 MALJ20X100-10-S
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-10-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 90 to 100 mm. This model is discontinued — the direct replacement is the MBLJ20X100-10-S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-10-S
The AirTAC MALJ20X100-10-S is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke stopper. The direct replacement is the MBLJ20X100-10-S, matching the 20 mm bore, 100 mm stroke, G1/8 port, and force ratings.
This -S variant includes a magnet for CS1-M / DS1-M reed switches, whereas the MBLJ replacement upgrades to CMSG / DMSG / EMSG sensors. The MALJ uses threaded covers, while the MBLJ features a riveted rolling-packed body. The fixed rubber bumper softens end impacts, but the adjuster is a travel stop, not a lock; it cannot hold a load without live air pressure.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-10-S Technical Specifications
| Model | Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-10-S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ20X100-10-S |
| Bore size | Ø20 mm |
| Stroke | 100 mm |
| Adjustable window | 90 – 100 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 |

| 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 MBLJ20X100-10-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 MBLJ20X100-10-S matches these values.

| S | Optional magnet for a CS1-M / DS1-M sensor (MBLJ uses CMSG/DMSG/EMSG). |

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-10-S Is Used
Label Applicator Wiper
Fine-tune the stroke end-position by up to 10 mm to press labels onto varying carton heights, ensuring the 8 mm rod stops cleanly via the rubber bumper.
Small Part Ejector
Adjust the rear stopper to time the ejection stroke of lightweight plastic caps from a molding machine, preventing the 132 N pull force from stressing delicate parts.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-10-S with MBLJ20X100-10-S
To replace the MALJ20X100-10-S, specify the MBLJ20X100-10-S and confirm the 20 mm bore, 100 mm stroke, 10 mm adjust code, G1/8 port, and M8x1.25 rod-end thread. Mounting is FA or LB only, with no back cover or SDB option. Transfer your CS1-M / DS1-M sensors to the new CMSG / DMSG / EMSG family. Remember the adjuster sets the 90-100 mm end position but is not a mechanical lock.
Stepping up to the 25 mm bore gives a 56% increase in push force for heavier payloads. At 100 mm stroke, keep the rod side-load minimized to prevent bending the 8 mm rod.
Upgrade checklist
- ✓ Order the MBLJ20X100-10-S (same bore/stroke/adjust)
- ✓ Same 90–100 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 MBLJ20X100-10-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-10-S FAQ
Yes, the MALJ20X100-10-S is discontinued. The direct replacement is the MBLJ20X100-10-S, which matches the 20 mm bore, 100 mm stroke, 10 mm adjust code, G1/8 port, and force ratings. You will need to upgrade your sensors from the old CS1-M / DS1-M switches to the new CMSG / DMSG / EMSG family.
The 10 mm adjuster provides a usable stroke window of 90-100 mm. The adjuster is a travel stop, not a load lock.
