An improved target wheel is provided for a bearing speed sensor. The target wheel includes an annular base which is sized to be press fit on a seat or extension of the inner race of a bearing. The base includes a first end and a second end. A plurality of encoding elements, in the form of spaced apart teeth, operatively extend from the first end of the base. The base is bent upwardly near the second end to form a portion which extends out of the plane of the base. This portion defines an angle of less than 90&#xb0; with the plane of the base, and preferably forms an angle of about 30&#xb0; to about 40&#xb0;.

Speed sensor target wheel with improved retention capability

A hub rotates around the end of an axle housing on a tapered roller bearing which is packed with grease. The axle housing, which is part of a drive axle, conveys lubricating oil to the interior of the hub, but the oil does not encounter the grease, for a seal, which is fitted into the end of the bearing, separates the oil from the grease. The seal pumps the grease back to the interior of the bearing and the oil away from the interior of the bearing.
