Product Overview: The 28580/21 Inch Tapered Roller Bearing
The 28580/21 is a single-row inch series Tapered Roller Bearing, a crucial component for applications requiring robust support for combined radial and axial loads. This bearing set consists of two separable parts: the cone assembly (inner ring with rollers), designated as 28580, and the cup (outer ring), designated as 28521. With a bore diameter of 57.15 mm, an outer diameter of 100 mm, and a total width of 25.4 mm, this bearing is engineered to precision inch-based standards. Its design allows it to handle heavy loads and provides true rolling motion, minimizing friction and operational temperatures. As a key part of our Inch Tapered Roller Bearings collection, the 28580/21 is a reliable choice for demanding industrial and automotive environments.
Key Features of the 28580/21 Bearing
- Separable Design: The cone and cup can be mounted independently, simplifying installation, inspection, and maintenance procedures.
- Combined Load Management: Expertly designed to accommodate high radial and axial (thrust) loads in one direction.
- Inch Series Standard: Manufactured to standardized inch dimensions, ensuring interchangeability and proper fitment in a wide range of equipment.
- High Load-Carrying Capacity: The geometry and number of rollers are optimized to distribute loads evenly, enhancing durability.
- Low Friction Operation: Tapered roller design ensures pure rolling contact, reducing friction, heat generation, and power loss.
- Durable Steel Construction: Made from high-quality, case-hardened bearing steel for superior wear resistance and extended service life.
