This type bearing has a very high radial load capacity but no axial load capacity.
With relative smaller radial measurements, it gives a higher limiting speed.
Fc type has two outer rings with ribs, full set of outer ring(ourter ring, rollers and cages), and one inner ring. Cages are rib-type.
Fcd type has two outer rings with ribs, full set of outer ring(ourter ring, rollers and cages), and two inner rings. Cages are rib-type.
Fcdp type has two outer rings without ribs, full set of rollers and cages, two inner rings, two rib rings and one middle snap rib ring,
Cages are pin-type.
In the view of position of lubricating bore, they have following types
Fc: the sides of outer ring have lubricating groove
Fc/a1: the radial surface has lubricating groove and oil bore¡£
Fcd: the sides of outer ring have lubricating groove.
Fcd/a1:the radial surface of outer ring has lubricating groove and oil bore.
Fcd/a13:both the sides and radial surfaces have lubricating groove and oil bore.
Fcdp:the radial surfaces of both outer ring and middle rib ring have lubricating groove and oil bore.
