Application
Bearing NTN 4T-02878/02820, 4T-02878/20 Tapered roller bearings are designed so that the center lines of the raceways and rollers all converge at a single point. Due to this design feature, rollers move along the center of the raceway surfaces. The tapered rollers are guided by the compound force of the inner and outer raceway surfaces which keep them pressed up against the large rib on the inner ring. Tapered roller bearings can be disassembled into parts the inner ring, rollers, and cage (collectively known as the "cone") and the outer ring (known as the "cup"). These are the bearing’s "subunits". Types ET and 4T tapered roller bearings are made of high-purity case hardened steel and are manufactured with a special heat treatment. Separators are made by stamping from sheet steel.
