Abstract

A screw actuator comprises a screw (1) and a nut (2) which are each provided with at least a helical groove (3,4), and a series of rollers or balls (5) which are in rolling contact with the grooves (3,4). A sleeve (6) is provided which surrounds the nut (2) at least partly. The sleeve (6) may carry a seal (7) which acts between the nut (2) and screw (1); e.g. a wiper seal. The seal (7) may be fixedly connected to the nut (2), and frictionally engage the screw (1).
