This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the drop-in replacement MBLJ40X150-50SH, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MALJ40X150-50SH is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 50 mm, giving a usable end-position window from 100 to 150 mm. This model is discontinued — the drop-in replacement is the MBLJ40X150-50SH.
The AirTAC MALJ40X150-50SH is a discontinued double-acting single-rod mini cylinder with a 40mm bore and 150mm stroke. The -50 adjust code provides a 50mm rear travel stop, creating a usable stroke window of 100-150mm so you can dial in the exact end position without external spacers. It delivers 628N push and 528N pull at 0.5MPa, features a G1/4 port, M12x1.25 rod thread, and a fixed rubber bumper. The exact drop-in replacement is the MBLJ40X150-50SH.
This SKU includes the -S magnet and H seal option. The MALJ uses threaded covers and the older CS1-M/DS1-M sensors, while the MBLJ replacement upgrades to a riveted rolling-packed body with CMSG/DMSG/EMSG switches. Remember the adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. Mounting is FA or LB only with no back cover or SDB.

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 MBLJ40X150-50SH 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 MBLJ40X150-50SH matches these values.

| 40 | Bore size in mm (20/25/32/40). |
| ×150 | Nominal stroke length in mm. |
| -50 | Adjustable amount: trim the end to a 100–150 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 in the 100-150mm window on a 628N push rod to set precise mold depth on a thermoforming press without machining new spacers.
Adjust the rear stop to fine-tune the pick height in an empty pallet dispenser, using the 880N push at 0.7MPa to break sticky stacks.
Set exact material deflection limits on a manual bending fixture, relying on the fixed rubber bumper to soften the end impact.
To replace the MALJ40X150-50SH, order the MBLJ40X150-50SH. Confirm the 40mm bore, 150mm stroke, 50mm adjust code, G1/4 port, PT threads, and FA/LB mounting. The -S magnet sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. The adjuster is a stop, not a lock, so add an external lock for held loads. If sizing force, step down to the 32mm bore (402N push at 0.5MPa) or step up if more force is needed. For a 150mm stroke, use central support to prevent rod bending and side-load wear.
Upgrade checklist
Yes, the MALJ40X150-50SH is discontinued. The exact drop-in replacement is the MBLJ40X150-50SH, matching the 40mm bore, 150mm stroke, 50mm adjust code, and G1/4 port. The MBLJ upgrades the body to a riveted rolling-packed design and changes the -S magnet sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
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 -50 adjust code lets you trim up to 50mm at the rear, giving a usable stroke window of 100-150mm. The adjuster is a travel stop, not a lock, and will not hold a load without live air.
