A ballscrew assembly (2) comprises a nut (4) having a first helical groove formed on a radially inner surface (10) and defining an axis (X), a screw (6) disposed along the axis (X) and within the nut (4), the screw (6) comprising a second helical groove formed on a radially outer surface (12) and opposed to the first helical groove so as to form a helical raceway, and a plurality of balls disposed in the helical raceway. An annular seal (18) is disposed radially between the nut (4) and the screw (6), the seal (18) comprising a resilient body (26) and a layer (32) formed of PTFE and disposed radially between the resilient body (26) and the screw (6) and configured to contact the radially outer surface (12) of the screw (6). An annular scraper (22) is disposed axially adjacent to the seal (18), the scraper (22) configured to receive fluid at one axial end and expel fluid at a second axial end.
