    摘要: A metal-to-metal face seal assembly comprises a static seal ring secured to a rotating element, such as a track roller of a tracked machine. The static seal ring has a seal face, and a dynamic seal ring has a seal face in sealing engagement with the seal face of the static ring. The dynamic seal ring has a ramp thereon extending at 8 degrees relative to horizontal in a direction away from the seal face thereof. The seal assembly further includes a seal housing, which may be the end collar of the track roller, having an annular ramp formed thereon confronting the ramp of the dynamic seal ring, which seal housing ramp extends at 10 degrees relative to horizontal. The ramps converge in a direction away from a seal plane defined by the mutually-engaging faces of the seal rings. A load ring disposed between the ramps is pre-compressed to its maximum strain level to provide the desired face loads on the seal faces.
