The BGL HMLL T series is a shaft lock nut that holds bearings, gears and pulleys in place and allows them to be removed later. Nodular cast iron construction makes tightening easier and helps prevent thread seizure when you take the assembly apart. It is secured with an MB washer or an MS safety lock.

The part number tells you the size. Examples include HMLL42T, HMLL46T, HMLL50T, HMLL55T, HMLL59T, HMLL63T, HMLL67T and HMLL71T. The digits indicate the size, and the T at the end marks this lock nut variant, as opposed to the withdrawal nut. Each size fits a specific shaft diameter and sleeve, so match the reference to the assembly on your machine. If you need a size outside this list, send the part number or model by WhatsApp and we will quote it.

These nuts are common where bearings, gears or pulleys are secured and then removed on a regular basis. You will find them in food, cement, mining and steel plants, and in any operation that does shaft work with adapter sleeves. They are also a practical choice where access is limited and you need a nut that will not seize during disassembly. MR Industrial Accessories supplies them to workshops, factories and maintenance services across the United States and in several Latin American countries.

When selecting a lock nut, consider the shaft diameter, the sleeve you will use and the clearance for your wrench. Nodular cast iron lets you tighten with less effort than some other materials and lowers the chance of the thread binding over time. Always secure it with an MB washer or an MS safety lock; that washer keeps the nut from backing off under vibration. Before mounting, confirm the thread is clean and that the nut threads on by hand. In high-vibration assemblies, inspect the lock at regular intervals.

Lock nuts come in different international standards, and cross-brand equivalents are matched by comparing diameter, pitch and locking method. If you have a part number from another brand or an unidentified part, we can point you to a compatible alternative. Carbon steel and stainless steel options are also available for different environments. Interchangeability depends on dimensions and the locking system lining up, not just the diameter. Before you replace a lock nut, check the standard and the washer type used on the equipment.
