29590/29522 Inch Tapered Roller Bearing 63.5x107.95x27.78mm Cone Cup Truck Equipment Bearing

1. Product Overview

29590/29522 is single row inch separable tapered roller bearing set, cone 29590 matched with cup 29522, dimension 63.5×107.95×27.78mm. Crowned tapered rollers reduce stress concentration and running heat. Separable cone and cup structure simplifies installation and maintenance. It bears combined heavy radial load and unidirectional axial thrust, widely used in truck hubs, forklift axles and small construction machinery gearboxes.
