Abstract
A temperature-robust polymer shroud for a roller bearing seal includes a shroud body and an inner diameter leg defining respective portions of a single continuous part. The shroud body encircles a rotation axis of the polymer shroud and extends predominantly in directions orthogonal to the rotation axis from an inner diameter to an outer diameter. The inner diameter leg connects to the shroud body at the inner diameter and encircles the rotation axis, wherein, along the entire inner diameter of the shroud body, the inner diameter leg is oriented at an oblique angle to the rotation axis to extend both (a) radially inward from the inner diameter and (b) axially away from the inner diameter along a first direction parallel to the rotation axis. A roller bearing seal includes a seal case, an elastomer lip, and the temperature-robust polymer shroud.
