Abstract: A primary objective of the present invention is to decrease the friction coefficient of the sliding face of a sliding element and to improve its seal performance. The sliding element disposes a plurality of elongate dimples in its first sliding face in which forward edges of the dimples relative to a rotational direction are inclined with respect to a tangential direction of a rotational circumference. The sliding element also disposes a second sliding face which has either a plane surface or second dimples and is located in the opposite side of the first sliding face relative to the process fluid.

Abstract: The present invention relates generally to a technical domain of a sliding element engaging a relative rotational motion. A primary objective of a sliding element of the present invention is to decrease a friction coefficient of the sliding face and to improve the seal performance. The element disposes dimples on at least one sliding face of a pair of relatively rotating sliding faces wherein the dimples are inclined towards a rotary direction when viewed along a radial direction. The sliding face of the sliding element also disposes a plurality of ring-formed dimple sections which form annuli of distinct diameters wherein the dimples are arranged along the individual annuli. The sliding face also disposes annular dam sections which are located between the individual dimple sections.

Abstract: A primary objective of the present invention is to decrease the friction coefficient of the sliding face of a sliding element and to improve its seal performance. The sliding element disposes a plurality of elongate dimples in the outer circumferential region and the inner circumferential region relative to a boundary reference line and the inclination of the dimples located in the outer circumferential region is different from that of the dimples located in the inner circumferential region. The longitudinally forward edge of the outer circumferential dimples relative to a rotational direction is inclined toward the outer circumference and the longitudinally forward edge of the inner circumferential dimples relative to a rotational direction is inclined toward the inner circumference.
