BGL KM series lock nuts are precision components used to hold adapter sleeves, bearings, gears and pulleys in place on a shaft. Made from nodular cast iron, they allow firm tightening with less effort and lower the risk of seizing when you need to remove them. They work together with MB washers or MS locks to provide positive locking. MR Industrial Accessories supplies them.

The KM code consists of the letters KM followed by a number that indicates size, starting at KM0 and going up to KM7 and beyond. That number does not correspond directly to a diameter; it is a reference linked to the diameter of the adapter sleeve or shaft where the nut is mounted. Suffixes, such as those in stainless steel versions, show the material or surface treatment. To identify the exact part, provide the full part number and the shaft diameter.

These nuts appear in food, chemical, petrochemical and general manufacturing plants, where rotating equipment requires dependable fastening. They are common on pumps, gearboxes, fans, conveyor belts and machine tools. In production lines that use bearings mounted on adapter sleeves, the nut maintains axial position and keeps the bearing from shifting under vibration or load.

When selecting a nut, consider the shaft diameter, the adapter sleeve type and the locking method. The MB washer or MS lock must match the thread and diameter. During assembly, clean the threads, apply the recommended torque and check that the washer seats in a shaft groove. The nodular cast iron of the KM series allows tightening with less effort and makes later removal easier. For corrosive environments, choose the stainless steel variant.

KM lock nuts can be interchanged among manufacturers that follow the same dimensional standards. If a customer provides a part number from another brand, an equivalent can be found in the BGL KM series. Thread and pitch usually match, but always verify the diameter and washer type. MR Industrial Accessories helps you confirm that the part fits your equipment, regardless of the original brand.
