A socket seal for a gyratory crusher is comprised of a ring with a pair of lips extending therefrom. The ring can have an outwardly expanding dovetail which is inserted into a slot in the piston or hemispherical bearing socket. The seal prevents downward flow of oil from the lubricated space between the hemispherical bearing ball and socket.
