Oil slinger with convective cooling of radial surface

An oil slinger system comprising:

• a seal runner comprising an annular radial member having a radius (R), an inner axially extending member, and an outer axially extending member having an axial length (L) such that a ratio (L/R) of the axial length to the radius is between 0.8 and 1.4, the annular radial member disposed at a first angle with respect to the outer axially extending member and the annular radial member disposed at a second angle with respect to the inner axially extending member;
• a heat shield in mechanical communication with the seal runner;
• and
• a volume bounded by an outer face of the annular radial member and an inner face of the heat shield;
• wherein the inner axially extending member comprises a radial oil passage configured to permit a lubricating oil to pass through the inner axially extending member to an inner face of the annular radial member such that the lubricating oil is driven by centrifugal force in the radially outward direction along the inner face of the annular radial member from the inner axially extending member to the outer axially extending member.
