Document Type and Number:
WIPO Patent Application WO/2021/205556
Kind Code:
A1
Abstract:
[Problem] To provide, in a pair of sliding components sliding relatively against each other on the sliding surfaces thereof, a sliding component allowing high sealability and low sliding torque to be realized, even when used in a wide rotation speed range, and regardless of the rotation direction. [Solution] The invention is a pair of sliding components sliding relatively to each other on the sliding surfaces S thereof, wherein at least one of the sliding surfaces is provided with dimple groups 51, 52, 53, and 54, each comprising an arrangement of a plurality of dimples 11 or 12 having respective opening portions shaped to have a major axis and a minor axis that are orthogonal to each other. The invention is provided with clockwise direction dimple groups 51 and 53 wherein the dimples 11 and 12 are arranged in a clockwise direction from the inner diameter side to the outer diameter side of the sliding surface, and counterclockwise direction dimple groups 52 and 54 wherein the dimples are arranged in a counterclockwise direction from the inner diameter side to the outer diameter side of the sliding surface.
