This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ20X200-100, 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).

The AirTAC Airtac MALJ20 Adjustable Mini Cylinder MALJ20X200-100 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 100 mm, giving a usable end-position window from 100 to 200 mm. This model is discontinued — the direct replacement is the MBLJ20X200-100.
The AirTAC MALJ20X200-100 is a discontinued adjustable-stroke mini cylinder. It provides a usable stroke window of 100-200 mm by trimming up to 100 mm at the rear screw. The direct replacement is the MBLJ20X200-100, matching bore, stroke, adjust code, port and force.
The rear adjuster acts as a travel stop, not a lock; it cannot hold a load without live air. This SKU lacks a magnet (-S), so it cannot accept a position sensor. The original MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ upgrade features a riveted rolling-packed body. Port is G1/8 with an M8x1.25 rod end.

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 MBLJ20X200-100 carries the same ratings.
| 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 MBLJ20X200-100 matches these values.

|---|---|
| 20 | Bore size in mm (20/25/32/40). |
| ×200 | Nominal stroke length in mm. |
| -100 | Adjustable amount: trim the end to a 100–200 mm window. |
| S | Optional magnet for a CS1-M / DS1-M sensor (MBLJ uses CMSG/DMSG/EMSG). |
Replacement: MALJ → MBLJ. No back-cover (CA/U/CM) and no SDB. Mounting: FA / LB.
Fine-tune the folding stroke on a packaging line carton erector; the 100 mm trim window lets you adjust flap travel for different box heights without adding external stops.
Use as a parts ejector on a small assembly fixture, adjusting reach to clear varying part sizes while relying on the fixed rubber bumper to soften the end impact.
Replace this MALJ20X200-100 with the direct replacement MBLJ20X200-100. Confirm the 20 mm bore, 200 mm stroke, 100 mm adjust code, G1/8 port, PT thread, and FA/LB mounting (no back cover or SDB). Because this SKU lacks the -S magnet, it cannot take a sensor; the MBLJ upgrade uses CMSG/DMSG/EMSG switches if you add one. The adjuster is a stop, not a lock.
With a 200 mm stroke on an 8 mm rod, beware of side-load and rod-bending forces; use a guide to prevent premature seal wear.
Upgrade checklist
Yes, the MALJ20X200-100 is discontinued. The direct replacement is the MBLJ20X200-100, which matches the 20 mm bore, 200 mm stroke, 100 mm adjust code, G1/8 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The -100 adjust code lets you trim the rear position by up to 100 mm, giving a usable stroke window of 100-200 mm. The adjuster is a travel stop, not a lock.
