AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X15-10-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X15-10-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 MALJ40X15-10-S 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 5 to 15 mm. This model is discontinued — the drop-in replacement is the MBLJ40X15-10-S.
The AirTAC MALJ40X15-10-S is a discontinued adjustable-stroke mini cylinder. As a drop-in replacement, use the MBLJ40X15-10-S, which matches the 40mm bore, 15mm stroke, G1/4 port and force ratings. This SKU provides a usable extension window of 5-15mm by trimming up to 10mm at the rear screw. It delivers 628N push and 528N pull at 0.5MPa.
This double-acting single-rod cylinder 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 will not hold a load without live air. For your upgrade, the MALJ uses threaded covers and a CS1-M/DS1-M magnet, while the MBLJ replacement features a riveted rolling-packed body and uses CMSG/DMSG/EMSG switches.

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 MBLJ40X15-10-S carries the same ratings.
| Pressure | Push force | Pull force |

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X15-10-S matches these values.

|---|---|
| 40 | Bore size in mm (20/25/32/40). |
| ×15 | Nominal stroke length in mm. |
| -10 | Adjustable amount: trim the end to a 5–15 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 5-15mm travel window to seat test probes precisely onto PCBs without over-traveling, using the 628N push force to ensure stable contact.
Fine-tune the electrode reach on a robotic spot welder, setting the exact 5-15mm end position to maintain consistent weld nuggets on steel panels.
Adjust the stroke stopper to press small bearings into housings, preventing bottoming-out while leveraging the 40mm bore's 880N push at 0.7MPa.
To replace this MALJ40X15-10-S with the MBLJ40X15-10-S, confirm the 40mm bore, 15mm stroke, 10mm adjust code, PT G1/4 port and M12x1.25 rod-end thread. Mounting is FA or LB only; there is no back-cover or SDB option. Because this is a -S magnet SKU, you must change your sensors: the old CS1-M/DS1-M switches will not fit the MBLJ, which requires CMSG/DMSG/EMSG switches. Remember the rear adjuster is a stop, not a lock; use an external lock for held loads.
For sizing flexibility, stepping down to the 32mm bore yields 402N push at 0.5MPa, while stepping up is not possible as 40mm is the largest MALJ bore. This 40mm bore provides 628N push at 0.5MPa (880N at 0.7MPa), giving you ample force for short, high-thrust clamping tasks.
Upgrade checklist
Yes, the MALJ40X15-10-S is discontinued. The exact drop-in replacement is the MBLJ40X15-10-S, matching the 40mm bore, 15mm stroke, 10mm adjust code, G1/4 port and 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 -10 adjust code lets you trim up to 10mm at the rear, giving a usable stroke window of 5-15mm. 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 adjuster is a travel stop, not a load lock.
