Structural Design: The 30307 bearing is a single-row tapered roller bearing from the metric 30000 series. The apexes of the conical surfaces of its inner ring, outer ring raceways, and rollers converge at a common point on the bearing's central axis. This design enables it to withstand combined loads, specifically significant radial loads and unidirectional axial loads
.
Features and Maintenance: The bearing typically uses a stamped steel cage and features a separable design. This means the inner ring assembly, which includes the rollers and the cage, can be installed separately from the outer ring (cup). This facilitates installation, disassembly, and maintenance
