Product Overview: The 18690/20 Inch Tapered Roller Bearing
The 18690/20 is a single-row inch series tapered roller bearing, a crucial component for applications requiring support for combined radial and axial loads. With a bore diameter of 42.86mm, an outer diameter of 79.38mm, and a thickness of 20.64mm, this bearing is engineered for precision and durability. As part of our Inch Tapered Roller Bearings collection, it is designed with separable components—the inner ring with rollers (cone) and the outer ring (cup)—which simplifies installation, removal, and maintenance procedures. The tapered geometry of the rollers and raceways ensures true rolling motion and low friction, making it an excellent choice for a wide range of industrial and automotive applications. Our commitment as a leading supplier is to provide high-quality components that deliver reliable performance under demanding conditions.
Key Features of the 18690/20 Bearing
- Separable Design: The cone (18690) and cup (18620) can be mounted independently, allowing for easier assembly and maintenance.
- Combined Load Capacity: Expertly designed to accommodate both radial and axial loads in a single direction, providing robust support.
- Inch Series Dimensions: Manufactured to standard inch-based dimensions, making it suitable for a variety of American and imperial-spec machinery.
- High Rigidity: Provides a high degree of stiffness to bearing arrangements, essential for applications requiring precise shaft guidance.
- Low Friction Operation: The optimized internal geometry minimizes friction and heat generation, leading to a longer service life and improved efficiency.
- Durable Construction: Made from high-purity, case-hardened bearing steel for exceptional strength and resistance to wear.
