A bearing assembly comprising a centrifugal debris trap for removing
contamination debris from lubrication fluid prior to lubrication of the
bearing assembly components is provided. The centrifugal debris trap
comprises an annular groove on an inner race such that with sufficient
centrifugal force, contamination debris in the lubrication oil is forced
into the groove and held there. Removal of contamination debris from the
lubrication oil prevents damage to bearing balls and races of the bearing
assembly, thus reducing bearing fatigue. A method for lubricating bearing
assembly components using the bearing assembly of the present invention
is also provided.
