  • Patent number: 8821019
    Abstract: A seal (1) for a hydrostatic linear guide with a given adjustment direction (5), with a longitudinal seal section (7, 7?) extending essentially parallel to the adjustment direction (5), and with a transverse seal section (8, 8?) extending essentially transverse to the adjustment direction (5), wherein a first lip seal with a projecting lip portion (12) extends along the longitudinal seal section and a second lip seal with a projecting lip portion (14) extends along the transverse seal section. A height of the projecting lip portion (12) of the first lip seal oscillates in a wave shape in the adjustment direction. With such a seal (1), both a high degree of static oil tightness and also a high degree of dynamic oil tightness are achieved for a hydrostatic linear guide.

  • Patent number: 8628249
    Abstract: A sealed, single row angular contact ball bearing which has a seal arranged at both axial ends in a region of the rims. One bearing ring has on both sides one receiving opening for the sealing lip carrier and the associated other bearing ring has on both sides one sealing face for the sealing lip. The rims are coordinated with one another in such a way that receiving openings and sealing faces lie in one plane at the same radial spacing from a bearing axis. It is ensured in this way that the same seal can be used for sealing the angular contact ball bearing of generic configuration on both sides.

  • Patent number: 7775721
    Abstract: A roller bearing which is sealed by a sealing washer that forms a rubbing seal and two gaps. As a result of positions which are spaced apart from one another in the axial direction of a pivot point and a center of mass of an elastic support part that bears the rubbing seal, the latter is loaded with an outwardly acting axial force in the event of an increased rotational speed as a result of the centrifugal force, with the result that the rubbing sealing lip is in contact with a lower force as the rotational speed increases.

  • Publication number: 20080247696
    Abstract: A sealed, single row angular contact ball bearing is distinguished by the fact that the seal (25, 40, 47, 48, 49, 50) is arranged at both axial ends in the region of the rims (21, 22, 23, 24), one bearing ring (16) having on both sides in each case one receiving opening (37, 44) for the sealing lip carrier (26) and the associated other bearing ring (15) having on both sides in each case one sealing face (30) for the sealing lip (29, 55, 56, 57, 58), and the rims (21, 22, 23, 24) being coordinated with one another in such a way that receiving openings (37, 44) and sealing faces (30) lie in in each case one plane (38, 39) at the same radial spacing from a bearing axis. It is ensured in this way that the same seal can be used for sealing the angular contact ball bearing of generic configuration on both sides.

  • Patent number: 7066471
    Abstract: A lip-type shaft seal is made of elastic material with a Shore A hardness of ?75, includes a radial sealing lip, which has a sealing edge to bear against a rotating component and terminates in a axial sealing lip, which has a sealing edge to rests in installed state against a contact surface. The axial sealing lip extends at an angle of ?35° in relation to a symmetry axis of the shaft seal, when the axial sealing lip has not been installed yet and is under no tension, and extends from the sealing edge of the radial sealing lip at a length of ?1.4 mm. When the shaft seal is installed, the axial sealing lip rests against the contact surface at an axial overlap of 0.05 to 0.55 mm.

  • Patent number: 6640541
    Abstract: A master cylinder for use in the power train of a motor vehicle to actuate the brakes or the friction clutch is designed to avoid the generation of screeching noise and/or the transmission of stray movements to the piston rod in response to shifting of the piston relative to the housing and relative to the sealing element(s) between the piston and the housing. This can be accomplished by causing the piston to turn relative to the housing and the sealing element(s) during axial movement in the housing and/or by installing one or more dampers between the piston and the housing and/or between the piston and the piston rod. The dampers can constitute separately produced parts and/or specially configured and/or finished surfaces provided on the piston and contacting the housing and/or the sealing element(s). The invention also relates to improvements in the configuration and/or the material(s) of the piston.
