This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X150-75, 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 MALJ25 Adjustable Mini Air Cylinder MALJ25X150-75 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 75 to 150 mm. This model is discontinued — the direct replacement is the MBLJ25X150-75.
The AirTAC MALJ25X150-75 is a discontinued double-acting, double-rod mini cylinder with a 75 mm rear travel stopper. It uses a G1/8 port, an M10x1.25 rod thread, and a fixed rubber bumper for end-of-stroke impact absorption. The direct replacement is the MBLJ25X150-75, which matches the bore, stroke, adjust code, force, and port.
Two key upgrade facts apply to the MBLJ successor: the older MALJ uses threaded covers, while the MBLJ features a riveted rolling-packed body. Also, this specific MALJ SKU lacks the -S magnet option, meaning it cannot accept a position sensor. The rear adjuster is a travel stop that sets the end position; it does not hold a load without live air pressure.

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 MBLJ25X150-75 carries the same ratings.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 206 N | 206 N |
| 0.7 MPa | 289 N | — |
| Max (@1.0 MPa) | 42 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 MBLJ25X150-75 matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 25 | Bore size in mm (20/25/32/40). |
| ×150 | Nominal stroke length in mm. |
| -75 | Adjustable amount: trim the end to a 75–150 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.
Adjust the rear stopper on a packaging line to synchronize flap folding depth for varying carton heights, avoiding the need to physically swap the cylinder.
Set the precise insertion depth for press-fitting connector pins, using the fixed rubber bumper to soften the end impact while tuning the exact seating height.
To replace the MALJ25X150-75, order the direct replacement MBLJ25X150-75. Confirm the 25 mm bore, 150 mm stroke, 75 mm adjust code, G1/8 port, PT thread, and FA or LB mounting (the series uses no back cover or SDB). Since this SKU lacks an -S magnet, it cannot hold a sensor. The adjuster is a stop, not a lock. At 150 mm stroke, minimize side-load to prevent rod bending.
Upgrade checklist
Yes, the MALJ25X150-75 is discontinued. The direct replacement is the MBLJ25X150-75, which matches the 25 mm bore, 150 mm stroke, 75 mm adjust code, G1/8 port, and FA/LB mounting. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The 75 mm adjust code lets you trim the rear end position, creating a usable stroke window from 75 mm to 150 mm. This SKU has no -S magnet, so it cannot take a position sensor.
