Abstract
A wiper seal assembly for sealing a ball screw actuator has an annularly shaped elastomeric seal element disposed about a longitudinal axis and separates a grease side from an environmental side. An annularly shaped internal support is disposed at least partially within the seal element. The seal element has a first arcuate surface configured to be disposed in an inner helical raceway of a shaft and faces the environmental side. A second arcuate surface is configured to be disposed in the inner helical raceway of the shaft and faces the grease side. An ice scraper seal faces the environmental side and is configured to make contact in at least 360 degrees around the longitudinal axis to or near the inner helical crest of the shaft. The first and second arcuate surfaces and the ice scraper seal the environmental side apart from the grease side.
