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-MBLJ32X75-50S, 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-MALJ32X75-50S
The AirTAC Airtac B01-MALJ Special Application Cylinder B01-MALJ32X75-50S 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 25 to 75 mm. This model is discontinued — the drop-in replacement is the B01-MBLJ32X75-50S.

About the Airtac B01-MALJ Special Application Cylinder B01-MALJ32X75-50S
The B01-MALJ32X75-50S is an application-dedicated (customer-specified) variant of the standard AirTAC MALJ32X75-50S, sharing the exact same physical specifications. The B01- prefix simply groups this into a dedicated line for specific customer builds. This discontinued double-acting mini cylinder features a 32mm bore and a 75mm stroke. The -50 adjust code lets you dial in the rear end position, creating a usable stroke window of 25-75mm without adding external stops. It delivers 402N of push force at 0.5 MPa.
The exact drop-in replacement is the MBLJ32X75-50S, matching the bore, stroke, adjust code, and G1/8 port. Two key upgrade facts: the MALJ uses threaded covers and a CS1-M / DS1-M magnet sensor system, whereas the MBLJ features a riveted rolling-packed body and uses CMSG / DMSG / EMSG sensors. The rear adjuster is a travel stop, not a lock; it sets the end position but will not hold a load without live air. End impact is softened by a fixed rubber bumper, as there is no adjustable air cushion.

Where the Airtac B01-MALJ Special Application Cylinder B01-MALJ32X75-50S Is Used
PCB Drill Depth Stop
Dial the 25-75mm window to set precise Z-axis travel for a PCB drilling spindle, using the 402N push force to drive the bit without over-penetrating the board.
Textile Loom Tensioner
Fine-tune the guide roller reach on a textile loom, adjusting the rear stopper on the fly to maintain fabric tension without swapping out the entire cylinder assembly.
Aluminum Extrusion Gate
Control the exit gate stroke on an aluminum extrusion line, trimming the 75mm stroke back to 50mm to sort different profile widths accurately.
Replacing the Airtac B01-MALJ Special Application Cylinder B01-MALJ32X75-50S with B01-MBLJ32X75-50S
To replace this B01-MALJ32X75-50S, order the MBLJ32X75-50S. Confirm the 32mm bore, 75mm stroke, -50 adjust code, PT thread form, and FA or LB mounting (there is no back cover or SDB option). If you need to step down a size, the 25mm bore neighbor provides 245N push at 0.5 MPa; if you need to step up, the 40mm bore neighbor provides 628N push at 0.5 MPa and upgrades the port to G1/4. Remember the adjuster only sets the end position and does not hold load without air pressure.
Upgrade checklist
- ✓ Order the B01-MBLJ32X75-50S (same bore/stroke/adjust)
- ✓ Same 25–75 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-MBLJ32X75-50S instead of this discontinued model.
Airtac B01-MALJ Special Application Cylinder B01-MALJ32X75-50S FAQ
Yes, it is discontinued. The exact drop-in replacement is the MBLJ32X75-50S. The B01- prefix only marks it as an application-dedicated variant; mechanically it is identical to the base MALJ32X75-50S. The MBLJ replacement matches the 32mm bore, 75mm stroke, 50mm adjust code, and G1/8 port, but upgrades the sensor family from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The 32mm bore provides 402N push and 346N pull at 0.5 MPa, 563N push at 0.7 MPa, and a maximum of 82 kgf at 1.0 MPa. The -50 adjust code is a travel stop that lets you trim the 75mm stroke back to a 25mm minimum. It sets the end position but does not hold the load without live air; end impact is absorbed by a fixed rubber bumper.
