What is claimed is:

1. A bearing assembly comprising:

a bearing cup having two ends,

a pair of outer raceways formed one adjacent each end of the bearing cup,

a pair of bearing cones forming a pair of inner raceways and having outwardly directed ends, two rows of tapered roller bearings each row received between one inner raceway and one outer raceway,

a center spacer positioned between the bearing cones to maintain the cones in spaced relation relative to one another,

each bearing cup having a cylindrical counterbore at each end radially outboard of the raceways,

a pair of wear rings, each having a first axially inwardly directed end in engagement with an outwardly directed end of a bearing cone,

and a pair of seals each having a first end fitted into one into each of the bearing cup cylindrical counterbores,

each seal having a second end including a resilient element to form a seal with one of the wear rings,

an annular backing ring,

a second end of each wear ring received in a cylindrical counterbore in an axially outwardly directed end of each annular backing ring,

and a circular shroud located radially outer and adjacent to one seal.

2. The bearing assembly of claim 1 wherein

the circular shroud assists the seal in keeping lubricant within a space between the cup and the cone.

3. The bearing assembly of claim 2 wherein

the circular shroud is comprised of a flexible strap of a synthetic material.

4. The bearing assembly of claim 2 wherein

the circular shroud includes a tab end and a receiving end to allow the circular shroud to be assembled into a circular shroud of adjustable circumference.

5. A bearing assembly comprising:

a bearing cup having two ends,

a pair of outer raceways formed one adjacent each end of the bearing cup,

a pair of bearing cones forming a pair of inner raceways and having outwardly directed ends, two rows of tapered roller bearings each row received between one inner raceway and one outer raceway,

each bearing cup having a cylindrical counterbore at each end radially outboard of the raceways,

a pair of wear rings, each having a first axially inwardly directed end in engagement with an outwardly directed end of a bearing cone,

and a pair of seals each having a first end fitted into one into each of the bearing cup cylindrical counterbores,

each seal having a second end including a resilient element to form a seal with one of the wear rings,

an annular backing ring,

a second end of each wear ring received in a cylindrical counterbore in each annular backing ring,

and a circular shroud located radially outer and adjacent to one seal.

6. The bearing assembly of claim 5 wherein

the circular shroud assists the seal in keeping lubricant within a space between the cup and the cone.

7. The bearing assembly of claim 5 wherein

the circular shroud is comprised of a flexible strap of a synthetic material.

8. The bearing assembly of claim 5 wherein

the circular shroud includes a tab end and a receiving end to allow the circular shroud to be assembled into a circular shroud of adjustable circumference.
