A wiper seal assembly for sealing a ball screw actuator includes a wiper element. An inside circumferential surface has a first helically shaped extension extending towards a longitudinal axis and is configured to be disposed within a roller ball screw thread. A plurality of micro-grooves is formed on the inside circumferential surface. An ice breaker element on its inside circumferential surface has a second helically shaped extension extending towards the longitudinal axis and is configured to be disposed within the roller ball screw thread. The second helically shaped extension extends to the front side of the ice breaker element forming an ice breaker lip. The wiper element is disposed adjacent to the ice breaker element. The wiper element and ice breaker element are mechanically locked in rotation in comparison to one another.
