Product Overview: The 25877/21 Inch Tapered Roller Bearing
The 25877/21 bearing is a single-row inch series Tapered Roller Bearing designed for exceptional performance under heavy load conditions. With a bore diameter of 30.16mm, an outer diameter of 62.0mm, and a total width of 20.64mm, this bearing is engineered to accommodate combined radial and axial loads simultaneously. Its design consists of two separable main components: the cone (inner ring assembly with rollers) and the cup (outer ring). This feature simplifies both installation and maintenance procedures, making it a practical choice for a wide array of industrial and automotive applications. The tapered geometry of the rollers and raceways ensures true rolling motion and minimizes friction, contributing to a longer service life and enhanced operational efficiency.
Key Features of the 25877/21 Bearing
- Separable Design: The cone (25877) and cup (25821) are separable, allowing for easier mounting, dismounting, and inspection.
- Combined Load Capacity: Expertly designed to handle substantial radial and single-direction axial (thrust) loads at the same time.
- Inch Series Standard: Manufactured to standard inch dimensions, ensuring compatibility with a wide range of machinery designed in North America and other regions using the imperial system.
- Low Friction Operation: The tapered roller design provides a true rolling motion, which reduces operational friction and heat generation.
- High-Quality Steel Construction: Made from robust, high-purity bearing steel for excellent durability, reliability, and resistance to wear and fatigue.
- Precise Geometry: Engineered for precise shaft alignment and load distribution, enhancing the overall performance and lifespan of the machinery.
