56425 - 56662, Tapered Roller Bearings
The 56662 timken is a cup for a single-row tapered roller bearing. This cup is an outer ring that can be combined with a separately available cone (the cage with rolling elements), to form a complete tapered roller bearing. The outer and inner rings have conical raceways and the roller elements are conical as well. This design enables tapered roller bearings to absorb radial and axial forces (in one direction). The greater the angle between the outer ring and the centre line of the bearing, the greater the axial load capacity.
