The BGL HMLL T series lock nut is a sleeve accessory that secures bearings, gears and pulleys on the shaft, and also allows them to be dismounted. It is made of nodular cast iron, a material that facilitates tightening and reduces the risk of seizing during disassembly. It is locked with an MB washer or MS safety lock. MR Accesorios Industriales sells it in Buenos Aires, Argentina, with more than 80 years of experience in industrial distribution.
The HMLL T designation is read by size: HMLL42T, HMLL46T, HMLL50T, HMLL55T, HMLL59T, HMLL63T, HMLL67T and HMLL71T. The number indicates the size, and the final T distinguishes this lock nut variant from the withdrawal nut. Each size corresponds to a specific shaft diameter and sleeve, so it is advisable to choose the reference according to the assembly where it is mounted. If you need a size that is not listed among these, write to us on WhatsApp with the part number or model and we will quote it for you.
These lock nuts are used in equipment where bearings, gears or pulleys must be secured and then dismounted frequently. They appear in machines in food, cement, mining and steel plants, and in general in any industry that performs shaft maintenance with adapter sleeves. They are also chosen in applications where access is difficult and a nut that does not seize during disassembly is needed. In Argentina, MR Accesorios Industriales supplies them to workshops, factories and maintenance services.
To select the lock nut, take into account the shaft diameter, the sleeve you are going to use and the space available for the wrench. Nodular cast iron allows tightening with less effort than other materials and reduces the risk of the thread seizing over time. Always lock it with an MB washer or MS safety lock: that washer prevents the nut from loosening due to vibration. When mounting, check that the thread is clean and that the nut goes on by hand before tightening. If the assembly works with a lot of vibration, check the lock periodically.
Lock nuts are available in different international standards, and equivalences between brands are resolved by comparing diameter, pitch and type of lock. If you bring the part number of another brand or an unidentified part, we will indicate the compatible alternative. There are also carbon steel or stainless steel options depending on the environment. Interchangeability depends on the dimensions and the locking system matching, not only the diameter. Therefore, before replacing a lock nut, it is advisable to verify the standard and the type of washer the equipment uses.

Frequently Asked Questions
- How do I choose the size of an HMLL T lock nut?
- The size is chosen according to the shaft diameter and the sleeve you are going to mount. Each HMLL T reference corresponds to a shaft size. If you have the sleeve or bearing part number, send it to us and we will indicate the nut that goes with it.
- What is the difference between nodular cast iron and steel?
- Nodular cast iron facilitates tightening and reduces the risk of the nut seizing during dismounting. Carbon or stainless steel is chosen for corrosive environments or more demanding loads. Both options are available depending on the application.
- With what washer is the HMLL T lock nut locked?
- It is locked with an MB washer or with an MS safety lock. That washer prevents the nut from loosening due to vibration. When mounting, check that the tab of the washer enters the shaft groove and that the nut sits properly.
