The BGL MB…A lock washer keeps a KM nut from turning once it has been tightened on an adapter sleeve. A straight tab on the inside of the washer sits in the shaft groove, and an outer tab is folded over the nut to stop it from rotating. The standard version is carbon steel, and a stainless steel option is available for harsh conditions. This makes the washer a practical choice where vibration or changing loads could otherwise loosen the assembly.
Reading the code helps you pick the right washer. MB…A belongs to the MB family, and the A means a straight internal tab. The number in place of the dots gives the size: MB1A, MB2A, MB3A, and so on through MB8A. Each size matches a particular shaft diameter and KM nut. Other variants such as MBL or MBA follow the same idea but can differ in width or tab shape. Always check the washer against the KM nut and adapter sleeve you plan to use.
These washers show up in many kinds of industrial equipment. You will find them in gearboxes, pumps, fans, conveyors, and agricultural machinery where adapter sleeves and KM nuts are common. They also appear on machine tool spindles and rolling mill shafts. In applications with vibration or dynamic loads, their role is important because they keep the nut from backing off and hold the bearing in place.
Mounting is straightforward. Thread the KM nut onto the adapter sleeve and tighten it with the correct wrench. Then set the MB…A washer so its internal tab enters the shaft groove. Finally, bend one outer tab against a flat of the nut to lock it. Make sure the washer sits flat and that the bent tab does not touch other parts. In corrosive settings, the stainless steel version is the better choice.
BGL MB…A lock washers can be used in place of other brands that follow the KM nut standard. To request a quote, give the full code or the shaft and nut dimensions. If you have a washer with no marking, we compare it with the MB, MBL, MBA, or AW series to find an equivalent. Diameter, width, and tab type all affect interchangeability, so it is best to confirm those details.
