This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X200-20S, 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 MALJ20X200-20-S
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-20-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 180 to 200 mm. This model is discontinued — the direct replacement is the MBLJ20X200-20-S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-20-S
The AirTAC MALJ20X200-20-S is a discontinued adjustable-stroke mini cylinder. It is double-acting with a single 8mm rod, a G1/8 port, and a 20mm rear travel stopper that creates a usable 180-200mm stroke window. The fixed rubber bumper absorbs end impact. The direct replacement is the MBLJ20X200-20-S, matching the 20mm bore, 200mm stroke, and port.
The rear adjuster sets the end position but does not hold load without live air. For your -S magnet, the legacy CS1-M/DS1-M switches apply, while the MBLJ upgrade moves to CMSG/DMSG/EMSG sensors and swaps the threaded covers for a riveted rolling-packed body.

| Bore size | Ø20 mm |
| Stroke | 200 mm |
| Adjustable window | 180 – 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 MBLJ20X200-20-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 MBLJ20X200-20-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-20-S Is Used
Wire Straightener Guide
Fine-tune the end position of the 8mm rod to set the final straightening die depth on a wire drawing line, trimming 20mm without adding external stops.
Label Applicator Wiper
Adjust the stroke window to match varying label widths on a packaging line, ensuring the wiper presses exactly to the container face.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-20-S with MBLJ20X200-20-S
To replace this MALJ20X200-20-S, order the direct replacement MBLJ20X200-20-S. Confirm the 20mm bore, 200mm stroke, 20mm adjust code, PT G1/8 port, M8x1.25 rod thread, and FA/LB mounting (no back cover or SDB). The -S magnet requires CMSG/DMSG/EMSG sensors on the new body. Remember the rear adjuster is a travel stop, not a lock. At 200mm stroke, watch rod-bending under side loads.
Upgrade checklist
- ✓ Order the MBLJ20X200-20-S (same bore/stroke/adjust)
- ✓ Same 180–200 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 MBLJ20X200-20-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-20-S FAQ
Yes, the MALJ20X200-20-S is discontinued. The direct replacement is the MBLJ20X200-20-S, which matches the 20mm bore, 200mm stroke, 20mm adjust code, G1/8 port, and mounting. You will need to upgrade your -S magnet sensors from the legacy CS1-M/DS1-M to the CMSG/DMSG/EMSG family.
The 20mm adjust code lets you trim the rear stopper for a 180-200mm usable stroke window. The adjuster is a travel stop, not a lock; it will not hold a load without live air.
