AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X300-40S, 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 MALJ32 Adjustable Mini Cylinder MALJ32X300-40-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 40 mm, giving a usable end-position window from 260 to 300 mm. This model is discontinued — the direct replacement is the MBLJ32X300-40-S.
The AirTAC MALJ32X300-40-S is a discontinued 32mm bore double-acting double-rod cylinder with a 300mm stroke and a 40mm rear travel stop. This yields a usable end-position window of 260-300mm.
The direct replacement is the MBLJ32X300-40-S. It matches the bore, stroke, 40mm adjust code, G1/8 port, and FA/LB mounting. Two upgrade facts: the MALJ uses threaded covers while the MBLJ uses a riveted rolling-packed body, and the MALJ -S magnet works with CS1-M/DS1-M switches while the MBLJ uses CMSG/DMSG/EMSG sensors.

| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X300-40-S |
| Bore size | Ø32 mm |
| Stroke | 300 mm |
| Adjustable window | 260 – 300 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
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 MBLJ32X300-40-S carries the same ratings.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 MBLJ32X300-40-S matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 32 | Bore size in mm (20/25/32/40). |
| ×300 | Nominal stroke length in mm. |
| -40 | Adjustable amount: trim the end to a 260–300 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 300mm reach on a packaging line flap folder without adding external stops, letting the 346N pull force tuck corrugated flaps smoothly.
Trim the rear 40mm stopper to set the exact cut-off position on an aluminum cutting saw, ensuring the 32mm rod retracts fully without hitting the fixture.
To replace the MALJ32X300-40-S, order the exact direct replacement MBLJ32X300-40-S. Confirm the 32mm bore, 300mm stroke, 40mm adjust code, PT G1/8 port, M10x1.25 rod thread, and FA/LB mounting (no back cover or SDB). The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air.
Because the stroke is 300mm, mind rod-to-side-load bending; use a guide rail to prevent rod deflection.
Upgrade checklist
Yes, the MALJ32X300-40-S is discontinued. The direct replacement is the MBLJ32X300-40-S, which matches the 32mm bore, 300mm stroke, 40mm adjust code, G1/8 port, and FA/LB mounting. The MBLJ upgrades the body to a riveted rolling-packed design and changes the magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The 40mm adjuster is a rear travel stop, not a lock; it lets you trim the end position to anywhere in the 260-300mm window. It does not hold the load without live air, and the cylinder uses a fixed rubber bumper, not an adjustable air cushion.
