Proposed is a novel coupling mechanism capable of applying a preload to a ball portion and a socket portion which constitute a coupling mechanism of a titling pad bearing, without using a spring element.

A bearing material including a substrate, and a sliding layer overlying the substrate, where the sliding layer includes fillers including wollastonite in a wt % range between 10 and 30%, barium sulfate in a wt % range between 5 and 15%, and pigment in a wt % range between 0.1 and 5%.

Provided are a sliding member and a sliding bearing which can improve the fatigue resistance. A sliding member having a base layer and a coating layer laminated on the base layer, in which the coating layer contains Bi or Sn as a first metal element, a second metal element which is harder than the first metal element and forms an intermetallic compound with the first metal element, C, and unavoidable impurities.

A sliding member including: a soft metal layer formed by stacking a crystal of soft metal, in which a coarse crystal is exposed on a surface of the soft metal layer, the coarse crystal has a particle length of 1.5 μm or more in a plane direction of the surface, and a distribution proportion of the coarse crystal is 5 to 50%, wherein the distribution proportion is a proportion of a circumscribed rectangle in a unit length of a virtual straight line, the circumscribed rectangle is applied to the coarse crystal appearing in a cross section of the soft metal layer, and the virtual straight line passing through the circumscribed rectangles in the cross section and parallel to a surface reference line of the soft metal layer is formed, an upper side of the circumscribed rectangle is parallel to the surface reference line of the soft metal layer, and the surface reference line is an average height of the surface of the soft metal layer appearing in the cross section.

Proposed is a novel coupling mechanism capable of applying a preload to a ball portion and a socket portion which constitute a coupling mechanism of a titling pad bearing, without using a spring element.

Disclosed herein a bearing that comprises a base, made of a metallic base material. The base comprises a cylindrical outer surface, a cylindrical inner surface that is opposite the cylindrical outer surface, and a central channel defined by the cylindrical inner surface and extending through the base. The bearing also comprises a selective transfer material embedded in the base. The selective transfer material is different than the metallic base material and is configured to release from the base in response to frictionally-induced pressure acting on the base.

A rolling bearing has an outer diameter surface of the outer ring which is a fitting surface with a housing and the inner diameter surface of the inner ring, which is a fitting surface with a shaft. The outer diameter surface of the outer ring or the inner diameter surface of the inner ring is coated with a bonded film containing an organic binder, a solid lubricant powder such as molybdenum disulfide powder, and a friction/wear modifier such as antimony oxide powder. According to the rolling bearing, a creep resistance is kept excellent without causing increase in cost and size and being deformed and softened.
