[tab name='More Information']
Single row tapered roller bearings are a type of rolling element bearing designed to handle both radial and axial loads. As the name suggests, these bearings consist of a single inner ring (cone), a single outer ring (cup), tapered rollers, and a cage to retain the rollers in position.

The unique design of tapered roller bearings allows them to support high radial and axial forces, making them suitable for a wide range of applications across various industries. The tapered shape of the rollers and raceways enables efficient distribution of loads along the bearing's axis, resulting in enhanced load-carrying capacity and improved performance.

The inner and outer rings of single row tapered roller bearings are designed to be separable, allowing for ease of assembly, disassembly, and maintenance. This characteristic simplifies installation and replacement procedures, reducing downtime and overall maintenance costs.

These bearings are commonly found in automotive applications, including wheel hubs, differentials, and transmissions. They are also extensively used in industrial machinery, such as gearboxes, construction equipment, agricultural machinery, and mining equipment, where they can withstand heavy loads and provide reliable performance under demanding conditions.

Single row tapered roller bearings are available in various designs, including different cone angles and cup geometries, to cater to specific application requirements. They can be manufactured with different cage materials, such as steel or brass, to optimise performance in various operating conditions.

Overall, single row tapered roller bearings are known for their durability, versatility, and ability to handle combined radial and axial loads, making them a fundamental component in numerous mechanical systems, ensuring smooth and efficient operation.
