Product Overview: The 28980/28921 Tapered Roller Bearing
The 28980/28921 is a single-row, inch series Tapered Roller Bearing, an essential component for applications requiring robust support for combined radial and axial loads. This bearing features a bore diameter of 57.15mm, an outer diameter of 104.775mm, and a total width of 29.37mm. Its design consists of two main separable parts: the cone (inner ring assembly, 28980) and the cup (outer ring, 28921). This separability simplifies mounting, dismounting, and maintenance procedures. The tapered geometry of the rollers and raceways creates a design that is highly effective at managing heavy loads and ensuring precise shaft alignment. Part of our Inch Tapered Roller Bearings collection, this component is manufactured to industry-standard specifications for reliable performance in demanding industrial and automotive environments.
Key Features of the 28980/28921 Bearing
- Two-Part Separable Design: The cone and cup can be mounted independently, simplifying installation and inspection.
- High Load Capacity: Engineered to handle significant radial and single-direction axial (thrust) loads simultaneously.
- Inch Series Dimensions: Specifically designed for machinery and equipment built to imperial standards.
- Tapered Roller Geometry: The design minimizes rolling friction and heat generation under load, extending the bearing's service life.
- Durable Construction: Manufactured from high-quality, case-hardened bearing steel for superior wear resistance and durability.
- Precise Operation: Provides accurate rotational guidance and maintains shaft alignment under heavy operational stress.
