This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the drop-in replacement B01-MBLJ40X150-50S, 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).
Airtac B01-MALJ Special Application Cylinder B01-MALJ40X150-50S
The AirTAC Airtac B01-MALJ Special Application Cylinder B01-MALJ40X150-50S 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 B01-MBLJ40X150-50S.

About the Airtac B01-MALJ Special Application Cylinder B01-MALJ40X150-50S
The AirTAC B01-MALJ40X150-50S is a discontinued, double-acting mini cylinder with a rear adjustable stroke. The B01- prefix marks this as an application-dedicated, customer-specified variant of the base MALJ40X150-50S, meaning it is mechanically identical to the standard catalog model. The 50 mm adjuster creates a usable stroke window of 100-150 mm, letting you dial in the exact reach without external stops. At 0.5 MPa this 40 mm bore delivers 628 N push and 528 N pull force.
The exact drop-in replacement is the MBLJ40X150-50S. Upgrading changes the construction from threaded covers to a riveted rolling-packed body. This -S magnet SKU originally used CS1-M / DS1-M switches, while the MBLJ uses CMSG / DMSG / EMSG sensors. Remember the adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air. End impact is softened only by a fixed rubber bumper.

Where the Airtac B01-MALJ Special Application Cylinder B01-MALJ40X150-50S Is Used
Press Fit Tooling
Dial the 100-150 mm window to press bearings to an exact depth, using the 628 N push force to seat components without bottoming out hard against the cylinder body.
Pallet Stopper Arms
Adjust the end position on conveyor lines to handle varying pallet depths, relying on the fixed rubber bumper to absorb the 880 N impact force at 0.7 MPa.
Welding Head Positioning
Fine-tune the electrode reach on a customer-specified spot welder, setting the travel stop precisely without needing to re-machine the mounting block.
Replacing the Airtac B01-MALJ Special Application Cylinder B01-MALJ40X150-50S with B01-MBLJ40X150-50S
To replace the B01-MALJ40X150-50S, install the MBLJ40X150-50S. Confirm the 40 mm bore, 150 mm stroke, 50 mm adjust code, G1/4 port, PT thread, and FA/LB mounting (no back cover or SDB). If sizing down, the 32 mm bore gives 402 N push at 0.5 MPa; if sizing up, you are at the largest MALJ bore. The -S magnet requires a sensor family change from CS1-M / DS1-M to CMSG / DMSG / EMSG. The rear adjuster is a stop, not a lock. At 150 mm stroke, watch for rod bending under side loads.
Upgrade checklist
- ✓ Order the B01-MBLJ40X150-50S (same bore/stroke/adjust)
- ✓ Same 100–150 mm adjustable window
- ✓ Adjuster is a stop, not a lock
- ✓ No back cover / SDB — plan an FA/LB mount
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check The rear adjuster sets the end position — it is not a load lock.
- check No back-cover / SDB on adjustable-stroke — use FA / LB.
- check Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the B01-MBLJ40X150-50S instead of this discontinued model.
Airtac B01-MALJ Special Application Cylinder B01-MALJ40X150-50S FAQ
Yes, the B01-MALJ40X150-50S is discontinued. The B01- prefix simply marks it as an application-dedicated variant of the base MALJ40X150-50S. The exact drop-in replacement is the MBLJ40X150-50S, which shares the same 40 mm bore, 150 mm stroke, 50 mm adjuster, G1/4 port, and 628 N push force at 0.5 MPa. You must upgrade the magnet switches from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The 50 mm adjust code lets you trim the rear position, creating a usable stroke window of 100-150 mm. The full force figures for this 40 mm bore are: 628 N push at 0.5 MPa, 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, and it cannot hold a load without live air.
