The BGL MBL series lock washer is a locking accessory placed between the KM lock nut and the adapter sleeve to prevent the nut from loosening due to vibration. Its design with a straight internal tooth engages the groove on the sleeve, and its tabs are bent over the nut. It is made of carbon steel, with a stainless steel option, and is available in several sizes for shafts of different diameters.

The MBL… designation identifies the washer by the diameter of the shaft or sleeve it corresponds to. For example, MBL24, MBL26 and MBL28 go with KML 24, 26 and 28 lock nuts, while MBL30, MBL32, MBL34, MBL36 and MBL38 correspond to larger nut sizes. The numeric suffix does not indicate the thickness or width of the washer, but the size of the sleeve-nut assembly it works with. To select the correct washer, you must identify the adapter sleeve and the KM lock nut to be mounted.

These washers are used in a wide variety of industrial equipment in Argentina: gearboxes, pumps, fans, conveyors, machine tools and belt or chain drive systems. They always go with adapter sleeves with KM lock nuts, which are common in bearings mounted on tapered shafts or adapter sleeves. They also appear in applications requiring secure and removable fastening, such as equipment that must be disassembled for periodic maintenance.

For correct mounting, first place the sleeve on the shaft and thread the KM lock nut without fully tightening it. Then position the lock washer so that its internal tooth fits into the groove on the sleeve. Next, tighten the nut with the appropriate wrench and, finally, bend one of the outer tabs of the washer over one face of the nut to lock it. It is essential that the internal tooth is properly seated; if it does not engage, the lock is not effective. In corrosive environments or with frequent washdowns, the stainless steel version is recommended.

MBL lock washers are interchangeable with those of other brands that follow the same standard for sleeves and KM lock nuts. When looking for a replacement, the safest approach is to compare the shaft diameter, the sleeve thread pitch and the shape of the internal tooth. The MB, MBL and MBA series share the straight internal tooth, while the AW series has an inclined tooth and is not directly interchangeable. If in doubt, the original washer code or the sleeve size allows you to identify the equivalent part.
