The BGL ZM series lock nut is a key accessory for mounting bearings, gears and pulleys on shafts. It is used together with adapter sleeves and lock washers to secure the axial position of the parts. Its nodular cast iron design allows tightening with less effort and reduces the risk of it seizing during disassembly. It is available in carbon steel or stainless steel, with dimensions according to international standards.

The ZM series designation is read with the letter Z followed by M and a number that indicates the nominal diameter of the shaft or adapter sleeve. For example, ZM6, ZM8, ZM10, ZM12, ZM15, ZM17, ZM20 and ZM25 cover a range of increasing sizes. The number is not an arbitrary code: it indicates the thread and the size of the nut. To select the right one, you have to cross-reference that number with the dimensions of the adapter sleeve or shaft where it is mounted.

These lock nuts are used in a wide variety of industries in Argentina: from food and chemical plants to metalworking shops, transport and agricultural machinery. They are common in equipment where bearings need to be secured with adapter sleeves, such as gearboxes, conveyors, pumps and fans. They also appear in applications with gears and pulleys that require a firm, removable axial fit.

For a correct selection, take into account the diameter and thread pitch of the shaft or adapter sleeve, and the type of lock washer you are going to use. The ZM series locks with an MB washer or with an MS safety lock. The nodular cast iron allows tightening with less torque and makes disassembly easier without damaging the thread. If the environment is corrosive, choose the stainless steel version. During mounting, check the alignment and apply the tightening torque according to specification.

As for equivalents, lock nuts are manufactured under international standards, which makes it easier to find replacements across different brands. If you bring the code from another brand or an unidentified part, at MR Accesorios Industriales we will tell you the compatible alternative. Interchangeability depends on the diameter, pitch and type of lock matching; that is why it is important to provide the complete code or the exact measurements.
