This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X30-10-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X30-10-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 MALJ40X30-10-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 20 to 30 mm. This model is discontinued — the drop-in replacement is the MBLJ40X30-10-S.
The AirTAC MALJ40X30-10-S is a discontinued 40mm bore double-acting mini cylinder with a 10mm rear stroke adjuster. This gives a usable end-position window of 20-30mm. It delivers 628N push and 528N pull force at 0.5 MPa. The direct drop-in replacement is the MBLJ40X30-10-S, matching the bore, stroke, adjust code, G1/4 port, and mounting.
This -S variant uses the older CS1-M/DS1-M reed switches, whereas the MBLJ upgrade uses CMSG/DMSG/EMSG sensors. The original MALJ features threaded covers, while the MBLJ uses a riveted rolling-packed body. The rear adjuster acts as a travel stop to fine-tune reach without external spacers, but it is not a lock and will not hold a load without live air. Impact is softened 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 MBLJ40X30-10-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 MBLJ40X30-10-S matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 40 | Bore size in mm (20/25/32/40). |
| ×30 | Nominal stroke length in mm. |
| -10 | Adjustable amount: trim the end to a 20–30 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 end position down 2mm from the 30mm max lets a 628N carbine router plunge set the exact copper clearance depth without adding physical shims to the spindle head.
A packaging line can trim the final 10mm stroke window to perfectly seat aluminum caps on varying bottle neck lengths using the 880N force at 0.7 MPa.
Setting the rear stop to 25mm guarantees a connector pin seats flush against a housing, preventing the 16mm rod from over-traveling and damaging the delicate PCB below.
To replace the MALJ40X30-10-S, order the exact drop-in MBLJ40X30-10-S. Confirm the 40mm bore, 30mm stroke, 10mm adjust code, G1/4 port, PT threads, and FA/LB mounting (no back cover or SDB allowed). Swap the CS1-M/DS1-M sensors for CMSG/DMSG/EMSG switches. If sizing down, the 32mm bore provides 402N push at 0.5 MPa; if stepping up, note 40mm is the largest MALJ bore available. The adjuster sets end position but does not hold load without air.
Upgrade checklist
Yes, the MALJ40X30-10-S is discontinued. The exact drop-in replacement is the MBLJ40X30-10-S, which matches the 40mm bore, 30mm stroke, 10mm adjuster, G1/4 port, and FA/LB mounting. You must upgrade your sensors from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family.
The 10mm adjuster creates a usable stroke window of 20-30mm. The full force figures are: 628N push at 0.5 MPa, 528N pull at 0.5 MPa, 880N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. The adjuster is a travel stop, not a lock, and cannot hold a load without live air pressure.
