This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X75-10S, 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 MALJ20X75-10-S
The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X75-10-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 65 to 75 mm. This model is discontinued — the direct replacement is the MBLJ20X75-10-S.

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X75-10-S
The AirTAC MALJ20X75-10-S is a discontinued double-acting mini cylinder with a 20 mm bore and 75 mm stroke. A rear screw lets you trim the end position up to 10 mm, creating a usable stroke window of 65-75 mm. The direct replacement is the MBLJ20X75-10-S, matching bore, stroke, adjust code, and G1/8 port.
This -S SKU includes a magnet for CS1-M or DS1-M switches; the MBLJ upgrade switches to CMSG, DMSG, or EMSG sensors. The MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ uses a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock, so it sets the end position without holding load without live air.

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 MBLJ20X75-10-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 MBLJ20X75-10-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X75-10-S Is Used
PCB Router Z-Axis Stop
Dial the 65-75 mm stroke window on a small PCB depaneling router to set the exact Z-axis cutting depth without adding spacers.
Label Applicator Tamp
Adjust the tamp stroke on a label applicator head by up to 10 mm to press labels onto slightly recessed carton surfaces cleanly.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X75-10-S with MBLJ20X75-10-S
To replace the MALJ20X75-10-S, order the MBLJ20X75-10-S. Confirm the 20 mm bore, 75 mm stroke, 10 mm adjust code, PT G1/8 port, and M8x1.25 rod thread. Mounting is FA or LB only; there is no back cover or SDB option. Because this is an -S model, plan to upgrade your CS1-M/DS1-M switches to CMSG/DMSG/EMSG sensors.
If sizing force, stepping down means no smaller MALJ bore exists, so you would look at a different frame. The 10 mm adjuster sets the end position but does not hold a load without air pressure; use an external lock for holding.
Upgrade checklist
- ✓ Order the MBLJ20X75-10-S (same bore/stroke/adjust)
- ✓ Same 65–75 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 MBLJ20X75-10-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X75-10-S FAQ
Yes, the MALJ20X75-10-S is discontinued. The direct replacement is the MBLJ20X75-10-S, which matches the 20 mm bore, 75 mm stroke, 10 mm adjust code, and G1/8 port. You will need to upgrade your sensors from the old CS1-M/DS1-M switches to CMSG/DMSG/EMSG switches.
The 10 mm adjust code lets you trim the 75 mm stroke, giving a usable window of 65-75 mm. The adjuster is a travel stop, not a lock.
