  • Friction-reducing geometric surface feature
    Patent number: 9261139
    Abstract: A sealing or bearing structure for sealing or separating moving surfaces is provided. The sealing or bearing structure includes a main body that defines a body axis going through the main body. A contact surface is configured to slidingly contact another surface, such as a rod, and defines a contact axis that is parallel to the body axis. At least one geometric surface feature, such as a shaped edge, is located between the body axis and the contact axis. The geometric surface feature has an entry angle that is less than 5 degrees relative to the contact axis.
