High-quality tapered roller bearing units from Koyo have high radial and axial (thrust) load capacities at low to intermediate speeds. Tapered roller bearings are available in single-row, two-row and four-row designs. With single-row bearings, the thrust carrying capacity is about 60% of the normal load capacity. Double-row bearings have a greater radial load capacity and can handle axial loads in both directions. Other designs for double-row bearings may include two outer rings and a single inner ring, or a single outer ring and two inner rings. Four-row tapered roller bearings consist of four rows of alternating tapered rollers. Most of these bearings are manufactured of low-carbon steels or alloy steels. Some specifications require case-hardened or through-hardened, high-carbon, bearing-quality steel. When low-carbon, carburized grades of steel are used, carbon and machining are used to produce a hardened case that can sustain bearing loads. The addition of carbon and alloys ensures the proper combination of a tough, ductile core and a hard, fatigue-resistant case. In addition to the bore size (ID) and outside diameter (OD), other important specifications for tapered roller bearings include section width, rated speed (oil), and static and dynamic load maxima in both the radial (normal) and axial directions.
