    摘要: A wheel bearing having an external, rotating, magnetic encoder which registers rotational speed of the bearing, and a magnetic particle trapping device spaced from the magnetic encoder to protect it against contamination. The trapping device includes a permanent magnet and a cooperating soft iron member which together form an L-shaped configuration relative to each other, with the magnet extending axially relative to the rotation of the wheel and the soft iron member extending radially, or vice versa. Contaminants are collected in a space between the soft iron member and the magnet. A magnetically non-conductive element may be provided to separate the trapping device from the metallic housing of the constant velocity joint on which the trapping device is mounted. A wiping finger may be provided to dislodge accumulated contaminant particles, which may then fall to the roadway.
