This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X25-20-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X25-20-S 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 MALJ40X25-20-S 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 5 to 25 mm. This model is discontinued — the drop-in replacement is the MBLJ40X25-20-S.
The AirTAC MALJ40X25-20-S is a discontinued 40mm bore, double-acting adjustable-stroke mini cylinder. It provides a usable stroke window of 5-25mm by letting you trim up to 20mm at the rear stopper. It delivers 628N push and 528N pull force at 0.5 MPa. The exact drop-in replacement is the MBLJ40X25-20-S, matching the bore, stroke, port, and force.
This -S model uses a CS1-M/DS1-M magnet, whereas the MBLJ upgrade uses CMSG/DMSG/EMSG switches. The MALJ has threaded covers, while the MBLJ features a riveted rolling-packed body. The rear adjuster is a travel stop, not a lock, so it sets the end position but will not hold a load without live air. It uses a fixed rubber bumper, not an adjustable air cushion.

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 MBLJ40X25-20-S carries the same ratings.
| Pressure | Push force | Pull force |

| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X25-20-S matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 40 | Bore size in mm (20/25/32/40). |
| ×25 | Nominal stroke length in mm. |
| -20 | Adjustable amount: trim the end to a 5–25 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 the 5-25mm window to set router depth on a PCB depaneling machine. The 628N push force handles the z-axis plunge without bottoming hard against the fixed rubber bumper.
Adjust the end position on an automotive connector crimp press. The 40mm bore provides stable high force, while the rear stop lets you fine-tune crimp height without adding external spacers.
Set precise travel on a manual rivet squeezer for aircraft skin panels. The 528N pull force retracts the rod, and the 20mm adjuster accommodates different grip lengths without swapping cylinders.
To replace this MALJ40X25-20-S, order the drop-in MBLJ40X25-20-S. Confirm the 40mm bore, 25mm stroke, 20mm adjust code, G1/4 port, PT thread, and FA/LB mounting (no back cover or SDB). Remember the adjuster is a stop, not a lock. The -S magnet changes sensor families from CS1-M/DS1-M to CMSG/DMSG/EMSG.
For sizing, step down to the 32mm bore for 402N push at 0.5 MPa, or step up to a larger ISO cylinder if you need more force. This 40mm bore gives 628N push and 880N at 0.7 MPa, making it ideal for compact high-force tasks.
Upgrade checklist
Yes, the MALJ40X25-20-S is discontinued. The exact drop-in replacement is the MBLJ40X25-20-S, which matches the 40mm bore, 25mm stroke, 20mm adjust code, and G1/4 port. 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.
At 0.5 MPa it provides 628N push and 528N pull. At 0.7 MPa it pushes 880N, with a maximum of 128 kgf at 1.0 MPa. The 20mm adjuster is a travel stop, not a lock; it lets you shorten the end position from 25mm down to a 5mm usable window, but it will not hold a load without live air.
