28580/28521 Tapered Roller Bearing Set, Inch Series, Single Row

28580/28521 The 28580/28521 is a single row tapered roller bearing set consisting of a cone (inner ring with rollers and cage) and cup (outer ring). This inch-series design provides high radial and thrust load capacity through its tapered raceway geometry. Tapered roller bearing sets are widely used in automotive wheel hubs, gearboxes, differentials, and industrial equipment where combined radial and axial loads must be supported. The separable design allows for precise adjustment of bearing clearance during installation.
