Structural Design: The 30304 bearing adopts a single-row tapered roller structure. The apexes of the conical surfaces of its inner ring, outer ring raceway, and rollers converge at a common point on the bearing's central axis. This design enables it to withstand combined radial and axial loads, primarily radial loads. The bearing typically uses a stamped cage and features a separable design, which facilitates installation, disassembly, and maintenance
.
Performance Characteristics: This type of bearing offers high load-carrying capacity, high rigidity, low friction coefficient, and a long service life. Specific preload effects can be achieved through adjustment during installation to meet the stiffness and precision requirements of different application scenarios
