The BGL MBL lock washer is a locking accessory that fits between a KM lock nut and an adapter sleeve to keep the nut from backing off under vibration. A straight internal tooth engages the sleeve groove while outer tabs bend over the nut. It comes in carbon steel with a stainless steel option and in a range of sizes for different shaft diameters.

The number in the MBL code refers to the sleeve and nut assembly, not to the washer's thickness or width. MBL24, MBL26 and MBL28 pair with KML 24, 26 and 28 lock nuts, while MBL30, MBL32, MBL34, MBL36 and MBL38 cover larger nut sizes. To pick the right washer, first identify the adapter sleeve and the KM lock nut you will mount.

These washers are common in gearboxes, pumps, fans, conveyors, machine tools and belt or chain drive systems. They are always used with adapter sleeves and KM lock nuts, which appear on bearings mounted on tapered shafts or adapter sleeves. They also suit applications that need secure but removable fastening, such as equipment taken apart for periodic maintenance.

Mounting sequence: place the sleeve on the shaft and thread the KM lock nut without fully tightening it. Position the lock washer so its internal tooth sits in the sleeve groove. Tighten the nut with the correct wrench, then bend one outer tab over a face of the nut to lock it. The internal tooth must be properly seated; if it does not engage, the lock will not hold. In corrosive environments or where frequent washdowns occur, choose the stainless steel version.

MBL lock washers interchange with other brands that follow the same standard for sleeves and KM lock nuts. For a replacement, compare the shaft diameter, the sleeve thread pitch and the shape of the internal tooth. The MB, MBL and MBA series share a straight internal tooth, while the AW series has an inclined tooth and is not directly interchangeable. If unsure, the original washer code or the sleeve size identifies the equivalent part.
