This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X200-75-S-LB, 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 MALJ20X200-75-S-LB
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-75-S-LB is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 125 to 200 mm. This model is discontinued — the direct replacement is the MBLJ20X200-75-S-LB.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-75-S-LB
The AirTAC MALJ20X200-75-S-LB is a discontinued double-acting, double-rod mini cylinder with a 20 mm bore, 200 mm stroke, and a 75 mm rear adjuster. This gives a usable end-position window of 125-200 mm. The direct replacement is the MBLJ20X200-75-S-LB, matching bore, stroke, adjust code, force, G1/8 port, and LB foot mount.
The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. A fixed rubber bumper softens end impact, but there is no adjustable air cushion. This MALJ has threaded covers and an -S magnet for CS1-M/DS1-M switches. The MBLJ upgrade features a riveted rolling-packed body and uses CMSG/DMSG/EMSG sensors. No back cover or SDB is used.

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 MBLJ20X200-75-S-LB 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 MBLJ20X200-75-S-LB matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-75-S-LB Is Used
Dispenser Valve Depth
Fine-tune the stroke window on an adhesive dispensing gantry to prevent the nozzle from crashing into the substrate, relying on the fixed rubber bumper to absorb the stop impact.
Small Parts Ejector
Adjust the kick-out reach on an injection mold stripper plate by up to 75 mm to clear different part geometries, using the LB foot mount to bolt the cylinder directly to the machine base.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-75-S-LB with MBLJ20X200-75-S-LB
To replace this MALJ20X200-75-S-LB, order the direct replacement MBLJ20X200-75-S-LB. Confirm the 20 mm bore, 200 mm stroke, 75 mm adjust code, PT G1/8 port, M8x1.25 rod thread, and LB foot mounting. The -S magnet changes sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG. Remember the adjuster is a stop, not a lock.
At 200 mm stroke, minimize side-load to prevent rod-bending, as the 8 mm carbon-steel rod with 20 um hard chrome is highly susceptible to deflection without guiding.
Upgrade checklist
- ✓ Order the MBLJ20X200-75-S-LB (same bore/stroke/adjust)
- ✓ Same 125–200 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 MBLJ20X200-75-S-LB instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-75-S-LB FAQ
Yes, the MALJ20X200-75-S-LB is discontinued. The direct replacement is the MBLJ20X200-75-S-LB, which matches the 20 mm bore, 200 mm stroke, 75 mm adjust code, G1/8 port, and LB mount. The MBLJ upgrades the body to a riveted rolling-packed design and requires CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M switches.
The usable adjustable window is 125-200 mm (200 mm stroke minus the 75 mm adjuster). The rear adjuster is a travel stop, not a lock, and cannot hold a load without live air.
