The BGL HMZ lock nut secures bearings, gears and pulleys on shafts when used with adapter sleeves. It is locked in place with an MB lock washer or MS lock to resist loosening. The nut is made of nodular cast iron, which supports smoother tightening and lowers the risk of seizing during disassembly. Depending on the application, it is available in carbon steel or stainless steel.
The HMZ code starts with the series and ends with a number that indicates size: as the number increases, so do diameter and pitch. Small sizes include HMZ18, HMZ19 and HMZ20, while HMZ24 or HMZ25 cover larger sizes. These nuts work together with adapter sleeves and lock washers. If you need help reading a code, send the part number on WhatsApp.
Typical applications are equipment with rotating shafts: conveyor belts, mills, pumps, fans and machine tools. They also suit bearing mounting on tapered shafts or adapter sleeves, where secure axial fixing is required. The design allows repeated mounting and disassembly without damaging the shaft. Industries that rely on these nuts include food, textile, metalworking, petrochemical and agro-industrial operations.
When selecting a nut, check the diameter and pitch of the shaft or adapter sleeve, along with the thread type. Nodular cast iron allows tightening with less torque and reduces the risk of galling, which makes disassembly easier. Always lock the nut with an MB lock washer or MS lock to prevent loosening from vibration. Lubricating the thread and aligning the assembly correctly are key to reliable mounting. If anything is unclear, consult us with your application details.
HMZ lock nuts are interchangeable with other brands that follow the same dimensional standards. When replacing a nut, confirm that diameter, pitch and thread type match the original part. Send us the code of the nut you need to replace and we can help you find the right equivalent. MR Industrial Accessories serves customers across the United States and in several Latin American countries, and our team can suggest equivalents and help you choose.
