  • Patent number: 6691837
    Abstract: A screw actuator comprises a nut and a screw each comprising helical grooves, said nut and screw engaging each other by rollers or balls which are in contact with said grooves, a lubricant being provided for the grooves and rollers or balls. Integrated in the actuator is a module, which is connected to at least the helical grooves of the nut and/or screw for replenishing the lubricant for the grooves and rollers or balls of the actuator.

  • Patent number: 6607059
    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).

  • Patent number: 6302404
    Abstract: A sealing device primarily for sealing off a slit-shaped space between two radially extending surfaces arranged about a shaft and axially displaceable relative to each other along the shaft includes a first sleeve-shaped seal part and an elastically resilient sealing body. The first sleeve-shaped part forms together with the shaft an axially open space facing the cooperating surface. The elastically, resilient sealing body has in an uncompressed state a cross-sectional area and/or a shape deviating from the area and/or shape of the axially open space. The sealing body when subjected to axial forces causing the sealing body surface and the cooperating surface to abut each other is compressed sealingly between the axial space and the cooperating surface, thereby creating a sealing engagement against the entrance of the slit-shaped space and against the shaft.

  • Patent number: 6062734
    Abstract: A bearing seal includes an annular body in sealing contact with the outer race of a bearing. The annular body includes a sealing resilient annular member fitted on a shield portion and projecting from the shield portion to contact in a sliding and sealing manner a sealing surface spaced apart from the bearing. The annular body is attachable to the outer race ring of the bearing by way of an annular bulge provided on the resilient member. The annular bulge is attachable by snap-action in a circumferential groove in the inner surface of the outer race ring of the bearing.
