GQZ 399A/394A Single Row Inch Tapered Roller Bearing 68.262×110×22mm Separable Cone And Cup Impact Resistant Design

399A/394A is single row imperial standard tapered roller bearing, consisting of separable inner cone (399A) and outer cup (394A). It can withstand combined heavy radial load and unidirectional axial thrust. Usually installed in opposite paired layout to bear bidirectional axial forces. Separable structure facilitates independent mounting, inspection and component replacement. Open design supports regular re-lubriion maintenance. Widely used on agricultural tractors, medium-duty truck wheel hubs, construction machinery, gear reducers and medium-heavy load rotary assemblies.
