28680/28622 Inch Tapered Roller Bearing 60.325x98.425x24.608mm Cone Cup Truck Machinery Bearing

1. Product Overview

28680/28622 is single row inch separable tapered roller bearing set, matched cone 28680 and cup 28622, dimension 60.325×98.425×24.608mm. Crowned tapered rollers eliminate stress concentration and reduce running heat. Separable cone and cup design simplifies installation and component replacement. It bears combined heavy radial load and unidirectional axial thrust, widely applied to truck wheel hubs, forklift drive axles and small construction machinery.
