This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X75-75, 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 MALJ25X75-75 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 0 to 75 mm. This model is discontinued — the direct replacement is the MBLJ25X75-75.
The AirTAC MALJ25X75-75 is a discontinued double-acting, double-rod mini cylinder with a rear adjustable stroke stopper. It has a 25mm bore, a 75mm base stroke, and a 75mm adjust code, giving you a usable end-position window of 0-75mm. The direct replacement is the MBLJ25X75-75, matching the bore, stroke, force, and G1/8 port.
This SKU lacks the -S magnet, so it cannot take a position sensor. The 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. Upgrading to the MBLJ25X75-75 moves you from threaded covers to a riveted rolling-packed body, and from the older CS1-M/DS1-M switches to CMSG/DMSG/EMSG sensors (if you later use an -S version).

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 MBLJ25X75-75 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 MBLJ25X75-75 matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 25 | Bore size in mm (20/25/32/40). |
| ×75 | Nominal stroke length in mm. |
| -75 | Adjustable amount: trim the end to a 0–75 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 end position to match varying insulation lengths on a wire processing line, fine-tuning the 75mm reach without swapping out the entire cylinder or adding external spacers.
Set a specific stroke window to tuck flaps on varying small carton sizes, relying on the fixed rubber bumper to absorb the 206N pull impact at the end of each cycle.
To replace the MALJ25X75-75, order the MBLJ25X75-75. Confirm the 25mm bore, 75mm stroke, 75mm adjust code, G1/8 port, PT thread, and FA/LB mounting (there is no back cover or SDB option). Since this SKU has no -S magnet, it cannot accept a sensor; the MBLJ upgrade enables CMSG/DMSG/EMSG switches if needed. Remember the adjuster is a stop, not a lock.
For this 75mm stroke, side load and rod-bending are minimal, but ensure straight-line motion to prevent premature seal wear.
Upgrade checklist
Yes, the MALJ25X75-75 is discontinued. The direct replacement is the MBLJ25X75-75, which matches the 25mm bore, 75mm stroke, 75mm adjust code, force, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The bore is 25mm with a G1/8 port. The 75mm adjust code allows you to trim the 75mm stroke down to 0mm, giving a usable window of 0-75mm.
