- They have inner and outer ring raceways that are designed to form an angle with respect to the bearing axis, allowing them to accommodate high-speed and high-precision applications.

Overall, in mechanical terms, a bearing serves as a critical component that enables controlled motion, reduces friction, and supports loads in a wide variety of mechanical systems, playing a fundamental role in the functionality and performance of machinery across industries.

In summary, taper roller bearings are used in a diverse range of applications across various industries, where their ability to support radial and axial loads, provide high load-carrying capacity, and withstand demanding conditions is essential.

- Main bearings, also known as crankshaft bearings, are designed to support the crankshaft within the engine block. They are positioned at the main bearing journals of the crankshaft and provide support for the rotational motion of the crankshaft. Main bearings are subjected to radial loads and are crucial for maintaining the alignment and smooth rotation of the crankshaft.
