摘要： 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.

摘要： A slinger for a roller bearing seal includes (a) an inner section extending at least in a first direction parallel to a rotation axis of the slinger, encircling the rotation axis and forming a plurality of tabs configured to pressure fit the slinger onto a rotor of a roller bearing seal, (b) an outer section extending at least in the first direction at a greater distance than the inner section from the rotation axis and encircling the rotation axis, and (c) a middle section encircling the rotation axis and spanning between the inner section and the outer section, wherein the inner section, the middle section, and the outer section define respective portions of a single continuous part.

摘要： In accordance with one aspect of the present disclosure, a roller bearing seal assembly is provided that includes a seal case and a rotor having a unitary, one-piece construction. The rotor is connected to the seal case and is rotatable relative to the seal case about an axis. The seal case and rotor include interfering portions that limit axial separation of the rotor and the seal case. In one embodiment, the rotor and seal case include at least one snap-fit connection that permits the rotor and seal case to be readily assembled. The at least one snap-fit connection includes the interfering portions which inhibit axial separation of the rotor and seal case after the rotor and seal case have been assembled.
