A thrust sliding bearingincludes a synthetic resin-made upper casing, a synthetic resin-made lower casing, and a synthetic resin-made thrust sliding bearing pieceinterposed between the upper and lower casingsand, and the thrust sliding bearing piecehas inner recessed portionsand outer recessed portionswhich are formed on its upper surfacein two rows including an inner row and an outer row and a lubricating oil filled in each of these inner recessed portionsand outer recessed portions, the inner recessed portionsand the outer recessed portionsbeing arranged with a phase difference of an angle &#x3b8;1=6&#xb0;.

Thrust sliding bearing

A sliding bearing () includes an upper casing () which is made of polyacetal resin as a synthetic resin, has an annular surface (), and serves as a first bearing body; a second bearing body () which is made of a synthetic resin, is superposed on the upper casing () so as to be rotatable about an axis (O), and has an synthetic resin-made annular surface () opposed to the annular surface (); and a synthetic resin-made annular sheet () which is interposed between the annular surfaces () and () and slidably abuts against at least one of the upper casing () and the bearing body ().

Sliding bearing

A thrust sliding bearing includes an upper casing having a polyacetal resin-made flat annular surface and a lower casing superposed on the upper casing so as to be rotatable about an axis of the upper casing and having a polyacetal resin-made annular surface opposing the annular surface of the upper casing.

Multilayered sliding members made of a lubricating composition containing polytetrafluoroethylene and 1 to 40 wt % of zinc oxide whiskers as a filler; and a porous sintered metal layer formed on a steel backing are disclosed, in which the lubricating composition is impregnated in and coated on the porous sintered metal layer.

Multilayered sliding member

Disclosed herein is a multilayered sliding member comprising a lubricating composition comprising polytetrafluoroethylene and 1 to 40 wt % of (i) zinc oxide whiskers or (ii) zinc oxide whiskers and fibrous magnesium oxysulfate, fan-shaped magnesium oxysulfate or a mixture thereof used as a filler; and a porous sintered metal layer formed on a steel backing, the lubricating composition being impregnated in and coated on the porous sintered metal layer formed on a steel backing.

Disclosed herein is a multilayered sliding member comprising a lubricating composition comprising polytetrafluoroethylene and, as filler, 1-25 wt % of fibrous magnesium oxysulfate, fan-shaped magnesium oxysulfate or a mixture thereof, and a porous sintered metal layer formed on a steel backing, the lubrication composition being impregnated in and coated on a porous sintered metal layer formed on the steel backing.

Disclosed herein are a fluororesin composition for a sliding member comprising a fluororesin, at least one of fillers selected from the group consisting of glass fiber, glass powder, carbon fiber and carbon powder, and a phosphate, and a sliding member thereof.
