  • Combined axially and radially loaded dirt excluder
    Patent number: 7810208
    Abstract: An improved rod wiper for excluding dirt and other environmental materials from a linear actuator is described. The annular wiper element includes an outwardly extended lip that is in constant engagement with the front face of the actuator housing. Not only does the lip assist in creating a seal with the housing, it redirects axial forces to have a radial component on the inwardly extended lips of the wiper element in contact with the rod to improve the seal of the wiper element and rod.
