Tapered roller bearings are a type of rolling-element bearing designed to support both radial and axial loads. They consist of an inner ring, an outer ring, and tapered rollers that are arranged in a way that allows for efficient load distribution. This design helps reduce friction and wear, making them suitable for high-speed applications. These bearings are commonly used in various industries, including automotive and machinery, due to their ability to handle heavy loads and provide stability. They are often found in applications like wheel hubs, gearboxes, and axles, where reliable performance is essential.
