This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X100-75S, 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 MALJ20X100-75-S
The AirTAC MALJ20X100-75-S is a discontinued double-acting double-rod mini cylinder with a rear adjustable stroke stopper. It trims up to 75 mm at the rear, giving a usable end-position window of 25-100 mm. The direct replacement is the MBLJ20X100-75-S, matching the G1/8 port and mounting.
This SKU includes a magnet (-S) for CS1-M / DS1-M switches, whereas the MBLJ upgrade uses CMSG / DMSG / EMSG sensors. The MALJ uses threaded covers, while the MBLJ features a riveted rolling-packed body. The fixed rubber bumper softens end impact, but the adjuster is a travel stop, not a lock—it will not hold a 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 MBLJ20X100-75-S carries the same ratings.
Theoretical Output Force (Ø20mm)

| 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 MBLJ20X100-75-S matches these values.

Where the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-75-S Is Used
Thin Sheet Metal Flange Alignment
Fine-tune the retract end position to align flimsy sheet metal flanges in a spot-weld jig, using the 132 N pull force to hold the part gently against the locator.
Dispensing Needle Depth Stop
Set a 30 mm extended reach for a glue dispensing needle on an automated cart, trimming the stroke back from 100 mm to prevent the fixed rubber bumper from crashing into the product.
Replacing the Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-75-S with MBLJ20X100-75-S
To replace the MALJ20X100-75-S, order the exact direct replacement MBLJ20X100-75-S. Confirm the 20 mm bore, 100 mm stroke, 75 mm adjust code, G1/8 PT port, M8x1.25 rod thread, and FA/LB mounting (no back cover or SDB). Note the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster sets end position but does not hold load without air; add an external lock for held loads.
At a 100 mm stroke on a 20 mm bore, rod side-load and bending moments are a real risk—ensure proper guidance to prevent binding.
Upgrade checklist
- ✓ Order the MBLJ20X100-75-S (same bore/stroke/adjust)
- ✓ Same 25–100 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 MBLJ20X100-75-S instead of this discontinued model.
Airtac MALJ20 Adjustable Mini Cylinder MALJ20X100-75-S FAQ
Yes, the MALJ20X100-75-S is discontinued. The direct replacement is the MBLJ20X100-75-S, which matches the 20 mm bore, 100 mm stroke, 75 mm adjust code, G1/8 port, and mounting. You will need to update your sensors from CS1-M/DS1-M to the CMSG/DMSG/EMSG family.
The -75 adjust code lets you trim the rear end position by up to 75 mm, creating a usable stroke window of 25-100 mm. The adjuster is a travel stop, not a lock.
