ABSTRACT:
A seal member for effecting a seal between a shaft intended to rotate at high rates and a housing through which the shaft extends has a carrier for mounting on one of the shaft or housing and a plurality of generally radially extending seal elements adapted to wipe on the other of the shaft or housing. Each seal element is in the form of a flexible strip the width of which in the axial direction is significantly greater than the strip thickness, whereby the strips exhibit great stiffness axially, but may flexibly seal in the circumferential direction.
