This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X200-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X200-20 in place of this model. 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 MALJ40 Adjustable Mini Cylinder MALJ40X200-20 is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 180 to 200 mm. This model is discontinued — the drop-in replacement is the MBLJ40X200-20.
The AirTAC MALJ40X200-20 is a discontinued double-acting, single-rod adjustable-stroke cylinder. It has a 40mm bore, a 200mm stroke, and a 20mm rear adjuster, giving a usable end-position window of 180-200mm. The exact drop-in replacement is the MBLJ40X200-20, which matches the original bore, stroke, force, G1/4 port, and mounting.
This 40mm bore generates 628N push and 528N pull at 0.5MPa (880N push at 0.7MPa). It uses a fixed rubber bumper, not an adjustable air cushion. The rear adjuster sets travel limits but does not hold loads without live air pressure. This SKU lacks a magnet (-S), so it cannot accept a position sensor. The original MALJ has threaded covers, while the MBLJ upgrade uses a riveted rolling-packed body.

| Adjustable window | 180 – 200 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |

| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | 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 MBLJ40X200-20 carries the same ratings.

| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X200-20 matches these values.

| 40 | Bore size in mm (20/25/32/40). |
| ×200 | Nominal stroke length in mm. |
| -20 | Adjustable amount: trim the end to a 180–200 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.
Dialing the 180-200mm reach lets you fine-tune carton flap closure on a packaging line without swapping the cylinder or adding external stops.
The 628N push force at 0.5MPa easily strips empty pallets from a magazine stack, while the rear stopper dials the exact 20mm push-off distance.
Set the precise end position on a conveyor belt tensioning jig; the fixed rubber bumper absorbs the repeated end-impact of the 200mm stroke.
To replace the MALJ40X200-20, select the MBLJ40X200-20. Confirm the 40mm bore, 200mm stroke, 20mm adjust code, PT G1/4 port, and M12x1.25 rod-end thread. Mounting is Basic, FA, or LB only; there is no back-cover or SDB option. Because this SKU lacks the -S magnet, it cannot take a sensor. If you need a sensor, choose an -S MBLJ variant, which uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. The adjuster is a travel stop, not a lock; add an external lock for held loads.
For sizing, step down to the 32mm bore (402N push at 0.5MPa) if your force needs are lower, or step up to a larger ISO cylinder if you need more than the 128kgf maximum this 40mm bore provides. The 200mm stroke is standard and safe without side-load concerns.
Upgrade checklist
Yes, the MALJ40X200-20 is discontinued. The exact drop-in replacement is the MBLJ40X200-20, which matches the 40mm bore, 200mm stroke, 20mm adjust code, force, G1/4 port, and mounting. The MBLJ upgrades the body to a riveted rolling-packed design from the original threaded covers.
The usable adjustment window is 180-200mm (200mm stroke minus the 20mm rear adjuster). The 40mm bore provides 628N push and 528N pull at 0.5MPa, 880N push at 0.7MPa, and a maximum of 128kgf at 1.0MPa. The rear screw is a travel stop only; it does not hold load without live air.
