This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X15-10S, 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).

About the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X15-10-S
The AirTAC MALJ20X15-10-S is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke stopper. Its direct replacement is the MBLJ20X15-10-S, which retains the 20mm bore, 15mm stroke, 10mm adjust code, G1/8 port, and mounting footprint. This SKU provides a usable stroke window of 5-15mm, letting you dial in the exact end position without external shims.
The -10 adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. The fixed rubber bumper softens end impact, but this is an adjustable stroke, not an adjustable cushion. This -S variant has a magnet for CS1-M/DS1-M switches, while the MBLJ upgrade moves to CMSG/DMSG/EMSG sensors with a riveted rolling-packed body replacing the MALJ's threaded covers.

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 MBLJ20X15-10-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X15-10-S Is Used
Wire Cutter Depth Stop
Trim the rear screw to shorten the cutting blade travel on an automated wire stripping line, preventing the blade from bottoming out and dulling prematurely.
Label Applicator Tamp
Fine-tune the tamp stroke for a 20mm bore label applicator, adjusting the end position by up to 10mm to accommodate varying box heights without swapping cylinders.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X15-10-S with MBLJ20X15-10-S
To replace this MALJ20X15-10-S, order the exact direct replacement MBLJ20X15-10-S. Confirm the 20mm bore, 15mm stroke, 10mm adjust code, G1/8 port, PT thread, and FA/LB mounting (there is no back cover or SDB option). Note the -S magnet changes sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG. If you need to step down from this 20mm bore, there is no smaller MALJ size, so 20mm is the minimum. Remember the adjuster is a stop, not a lock.
Upgrade checklist
- ✓ Order the MBLJ20X15-10-S (same bore/stroke/adjust)
- ✓ Same 5–15 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 MBLJ20X15-10-S instead of this discontinued model.
