This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X100-10, 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 MALJ25X100-10 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 10 mm, giving a usable end-position window from 90 to 100 mm. This model is discontinued — the direct replacement is the MBLJ25X100-10.
The AirTAC MALJ25X100-10 is a discontinued double-acting, double-rod mini cylinder with a 10 mm rear adjustable stroke stopper. It provides a usable stroke window of 90-100 mm. The direct replacement is the MBLJ25X100-10, which matches the bore, stroke, force, and mounting.
This SKU lacks the -S magnet code, so it cannot accept a position sensor. The rear adjuster is a travel stop, not a lock; it cannot hold a load without live air pressure. The original MALJ features threaded covers and a fixed rubber bumper, whereas the MBLJ upgrade uses a riveted rolling-packed body. Both designs rely on a heterogeneous grease-retaining seal and a 20 um hard chrome carbon-steel rod.

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 MBLJ25X100-10 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 MBLJ25X100-10 matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 25 | Bore size in mm (20/25/32/40). |
| ×100 | Nominal stroke length in mm. |
| -10 | Adjustable amount: trim the end to a 90–100 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.
Dial in the 90-100 mm descent on a PCB depaneling router to cut exact depths without repositioning the cylinder block.
Set a precise 90 mm bottom position on a small assembly press, letting the fixed rubber bumper absorb the 50 kgf peak impact.
To replace the MALJ25X100-10, specify the MBLJ25X100-10. Confirm the 25 mm bore, 100 mm stroke, 10 mm adjust code, G1/8 port, PT thread, and FA or LB mounting. This unit has no -S magnet, so no sensor is used; if you later need a switch, the MBLJ takes CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M. Remember the adjuster sets end position but does not hold load.
Upgrade checklist
Yes, the MALJ25X100-10 is discontinued. The direct replacement is the MBLJ25X100-10, which keeps the same 25 mm bore, 100 mm stroke, 10 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The 10 mm adjuster trims the rear position, giving a usable stroke window of 90-100 mm. This adjuster is a travel stop, not a lock.
