NTN LM545849A is a single-row tapered roller bearing cone with a straight bore, part of the LM series inch series. Designed for high radial and axial load capacity in industrial gearboxes, axle housings, and heavy machinery. This cone is used with a matching cup (sold separately) to form a complete tapered roller bearing assembly.

How do I choose the right type of bearing for my application?
Start with the load and how it’s applied. You need to know if you’re dealing with radial loads, axial loads, or a mix of both. Then look at speed, operating environment, and space constraints. For example, ball bearings are great for high speed and lighter loads, while roller bearings handle heavier loads but usually at lower speeds. If there’s contamination, moisture, or heat involved, you may need sealed bearings or specific materials. In most cases, the right choice comes down to matching load type, speed, and environment to the bearing design.
