This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBLJ40X150-30-S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBLJ40X150-30-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 MALJ40X150-30-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 120 to 150 mm. This model is discontinued — the drop-in replacement is the MBLJ40X150-30-S.
The AirTAC MALJ40X150-30-S is a discontinued double-acting single-rod cylinder with a 40 mm bore and 150 mm stroke. It features a rear adjustable stopper that trims up to 30 mm, yielding a usable reach window of 120-150 mm. It delivers 628 N push and 528 N pull at 0.5 MPa. The exact drop-in replacement is the MBLJ40X150-30-S, matching bore, stroke, port, and force.
This -S SKU includes a magnet for CS1-M or DS1-M switches, which upgrades to CMSG/DMSG/EMSG sensors on the MBLJ. The MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ features a riveted rolling-packed body. The adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air.

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 MBLJ40X150-30-S carries the same ratings.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Single-rod force, same as a standard MAL of this bore. The MBLJ40X150-30-S matches these values.
| MALJ | Adjustable-stroke aluminum mini cylinder, double acting (discontinued). |
|---|---|
| 40 | Bore size in mm (20/25/32/40). |
| ×150 | Nominal stroke length in mm. |
| -30 | Adjustable amount: trim the end to a 120–150 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 end position to halt 40 mm pallets precisely without moving the cylinder body, using the 628 N push force to halt heavy goods.
Set the 120-150 mm reach window to press bearings into housings, relying on the fixed rubber bumper to soften the final impact.
Adjust the stroke on the fly to fold varying carton sizes on a single line, using the G1/4 port for high flow during rapid cycles.
To replace the MALJ40X150-30-S, order the MBLJ40X150-30-S. Confirm the 40 mm bore, 150 mm stroke, 30 mm adjust code, G1/4 port, M12x1.25 rod thread, and FA or LB mounting (no back cover or SDB). The -S magnet changes sensor families from CS1-M/DS1-M to CMSG/DMSG/EMSG. Remember the rear adjuster is a travel stop, not a lock.
For sizing, step down to the 32 mm bore for 402 N push at 0.5 MPa, or step up to a larger ISO cylinder if your application exceeds 628 N. At 150 mm stroke, avoid side-load rod-bending by guiding the load properly.
Upgrade checklist
Yes, the MALJ40X150-30-S is discontinued. The exact drop-in replacement is the MBLJ40X150-30-S, matching the 40 mm bore, 150 mm stroke, 30 mm adjust code, and G1/4 port. The MBLJ upgrades the body to a riveted rolling-packed design and switches sensors to CMSG/DMSG/EMSG.
The usable stroke window is 120-150 mm (150 mm stroke minus the 30 mm rear adjuster). Force figures are 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. The adjuster is a travel stop, not a lock.
