More Information
Summary:Provided are a sliding component, such as a mechanical seal ring, which is capable of maintaining superior sliding characteristics even in the long-term continuous use thereof, as well as a mechanical seal, a faucet valve, and a rolling support device, each of which includes the sliding component. The sliding component includes a stationary member, and a movable member contactedly sliding on the stationary member. The stationary member and the movable member are respectively composed of a silicon carbide sintered body containing graphite. The content of the graphite in one of the stationary member and the movable member is at least 4% by mass greater than in the other. Thus, the sliding component includes the stationary member and the movable member which are a combination of those having different contents of graphite. Owing to a high lubricating effect, the superior sliding characteristics can be maintained, permitting a long-term continuous sliding.
