In this paper, through test of electric conducting, sealing, and friction performance of 1:4 small sample of flexible electric conducting sealing system, and test of distortion follow-up performance, sealing effect, and fatigue life of 1:1 large sample, we conclude that under the condition without oil film on sealing surface, the sealing device supported by graphite seal ring and metal bellows has good electric conduction. With distortion of sealing surface, the effect of sealing is good and the fatigue life is long.

Keywords: Elastic component, Metal bellows, Seal ring.
