At least one wiping bead being a second helically shaped extension having a second pitch extending towards a longitudinal axis is disposed at least partially over the first helically shaped extension. The at least one wiping bead is configured to make contact with the roller ball screw thread. A cylindrical ring is in contact with and at least partially disposed about the seal element. The seal element is at least partially bonded to the cylindrical ring. The seal element has a first coefficient of thermal expansion and the cylindrical ring has a different second coefficient of thermal expansion.
