YINGHAI company is a professional manufacturer of laminar ring.

YINGHAI laminar seal ring set is a metallic labyrinth seal consisting of multiple rings in a groove . the arrangement and the specific orientation of the rings are dictated by the application and the severity of the rings are dictated by the application and the severity of the environment.

There are 16 series of standard imperial and Metric laminar seal ring configuration from which to select 8 of these series are sets consisting of single-turn rings. the other 8 seriess are sets consisting of double-turn rings.within each series are operational ring-set configurations in both imperial and metric sizes.the selection of the appropriate set should be determined by the application.

For some applications a complete labyrinth configuration is necessary due to a severe environment where contamination is highly probable.
In other applications design engineers can keep the groove dimensions minimal by specifying laminar sets with rings clinging either to the bore or to the shaft.
