Structural Design: The 30308 bearing is a single-row tapered roller bearing. Its design features conical surfaces on the inner ring, outer ring raceways, and rollers, with their apexes converging at a common point on the bearing's central axis. This structure enables it to simultaneously withstand significant radial loads and axial loads in one direction (combined loads)
.
Features and Installation: The bearing typically employs a separable design. This means the inner ring assembly (comprising the inner ring, rollers, and cage) can be installed separately from the outer ring (cup), which greatly facilitates installation, adjustment, and maintenance
. During installation, the clearance can be adjusted to preset an appropriate value, meeting the stiffness and rotational accuracy requirements of different application scenarios .
