The BGL HMZ series lock nut is a key accessory for mounting bearings, gears and pulleys on shafts. It is used together with adapter sleeves and locked with an MB lock washer or MS lock to prevent it from loosening. Made of nodular cast iron, it offers smoother tightening and reduces the risk of seizing during disassembly. Available in carbon steel or stainless steel, depending on the application. MR Accesorios Industriales sells it in Buenos Aires, Argentina.

The HMZ designation followed by a number identifies the BGL lock nut series. The number indicates the size: the higher the number, the larger the diameter and pitch. For example, HMZ18, HMZ19 and HMZ20 are small sizes, while HMZ24 or HMZ25 correspond to larger sizes. These nuts are used with adapter sleeves and lock washers. If you need help interpreting the code, write to us on WhatsApp with the part number.

HMZ nuts are used in a wide variety of industries in Argentina: food, textile, metalworking, petrochemical and agro-industrial. They are common in equipment with rotating shafts, such as conveyor belts, mills, pumps, fans and machine tools. They are also used when mounting bearings on tapered shafts or adapter sleeves, where precise and secure axial fixing is required. Their design allows repeated mounting and disassembly without damaging the shaft.

To select the correct nut, take into account the diameter and pitch of the shaft or adapter sleeve, and the thread type. Nodular cast iron allows tightening with less torque and reduces the risk of galling, which makes disassembly easier. It must always be locked with an MB lock washer or MS lock to prevent loosening due to vibration. Lubrication of the thread and correct alignment of the assembly are key to reliable mounting. If in doubt, consult us with the details of your application.

HMZ lock nuts are interchangeable with other brands that follow the same dimensional standards. When replacing a nut, check that the diameter, pitch and thread type match the original part. MR Accesorios Industriales can advise you to find the right equivalent if you send us the code of the nut you need to replace.
