USMA TAPERED ROLLER BEARING 30310 30311 30312 30313 ROLLER BEARING
Tapered roller bearings are separable bearings, inner and outer rings have a tapered raceway.
This kind of bearing according to the number of columns loaded roller into single row, double row and four-row tapered roller bearings, such as different types of structures. Single row tapered roller
bearings can withstand the radial load and single direction axial load. When the bearing radial load, will
produce an axial force component, so when need another affordable bearing axial force in the opposite
direction to be balanced.
