Product Overview: The 28584/21 Inch Tapered Roller Bearing
The 28584/21 is a high-performance, single-row Inch Tapered Roller Bearing with dimensions of 57.15mm (Bore) x 110.007mm (Outer Diameter) x 26.988mm (Thickness). This bearing consists of two separable components: the cone (inner ring assembly, 28584) and the cup (outer ring, 28521). This design simplifies installation and maintenance. Engineered to handle a combination of radial and axial loads, it is an essential component in a wide variety of industrial and automotive applications. Its tapered geometry ensures true rolling motion and low friction, even under heavy loads.
As a leading supplier of industrial mechanical parts, we ensure our 28584/21 bearings are manufactured to precise industry standards for reliable performance and longevity. This bearing is part of our comprehensive collection of Tapered Roller Bearings, designed to meet the rigorous demands of modern machinery. Its robust construction makes it ideal for applications requiring high load-carrying capacity and durability.
Key Features of the 28584/21 Bearing
- Separable Design: The cone and cup can be mounted independently, which simplifies assembly, disassembly, and inspection routines.
- Combined Load Management: Expertly designed to accommodate both radial and axial loads in a single direction, providing versatile support.
- Inch Series Standard: Manufactured to imperial (inch) dimensions, making it suitable for a wide range of equipment, particularly from North America.
- High Load Capacity: The tapered raceways and rollers create a large contact area, enabling the bearing to support heavy loads effectively.
- Low Friction Operation: The logarithmic roller profile reduces edge stress and ensures smooth, efficient rotation, minimizing heat generation.
- Durable Construction: Made from high-carbon chromium bearing steel for exceptional hardness, wear resistance, and a long service life.
