This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ25X100-100S, 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 MALJ25X100-100-S 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 0 to 100 mm. This model is discontinued — the direct replacement is the MBLJ25X100-100-S.
The AirTAC MALJ25X100-100-S is a discontinued double-acting, double-rod mini cylinder with a 25 mm bore and a 100 mm stroke. A rear stopper screw lets you trim up to 100 mm, giving a usable end-position window of 0-100 mm.
The direct replacement is the MBLJ25X100-100-S, matching the bore, stroke, port, and force. The MALJ uses threaded covers, while the MBLJ upgrades to a riveted rolling-packed body. The adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. Impact is softened only by a fixed rubber bumper.

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 MBLJ25X100-100-S 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 MBLJ25X100-100-S 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. |
| -100 | Adjustable amount: trim the end to a 0–100 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.
Fine-tune the rear stopper to 85 mm on a packaging line flap folder, matching varying box heights without swapping hardware while the cylinder retracts with 206 N pull force.
Adjust the end position precisely on an automotive wire harness jig, letting the fixed rubber bumper absorb the end impact as the rod forms copper bundles.
Replace this MALJ25X100-100-S directly with the MBLJ25X100-100-S, confirming the 25 mm bore, 100 mm stroke, 100 mm adjust code, G1/8 port, M10x1.25 rod thread, and PT thread form. Mounting is FA or LB only; there is no back-cover or SDB option. The -S magnet changes sensor families from the older CS1-M / DS1-M to the new CMSG / DMSG / EMSG switches. Remember the adjuster is a stop, not a lock.
For strokes of 100 mm or more, watch rod-to-side-load bending and provide guide rails to prevent rod distortion.
Upgrade checklist
Yes, the MALJ25X100-100-S is discontinued. The direct replacement is the MBLJ25X100-100-S, which matches the 25 mm bore, 100 mm stroke, 100 mm adjust code, G1/8 port, and mounting. The MBLJ upgrades the threaded covers to a riveted rolling-packed body and changes the -S magnet sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The -100 adjust code allows trimming up to 100 mm at the rear, creating a usable stroke window of 0-100 mm. The adjuster is a travel stop, not a lock, and will not hold a load without live air.
