摘要： A synthetic resin bearing and a scroll compressor using the same are provided. In the synthetic resin bearing as a journal bearing fixed to an orbiting scroll or a main frame and relatively rotated with respect to a rotational shaft in a scroll compressor, the journal bearing is made of a PEEK material, and a thickness t of the journal bearing is smaller than a thickness t1 with which a temperature in a contact surface thereof with the rotational shaft during an operation of the scroll compressor corresponds to a glass transition temperature.

摘要： A scroll compressor having a bearing is provided. The scroll compressor includes: a casing; a main frame fixed to the casing and having a shaft insertion hole formed therein; a fixed scroll fixed to the casing and disposed above the main frame; an orbiting scroll forming a compression chamber together with the fixed scroll and having a boss portion formed on a lower surface thereof; a rotational shaft having an end portion insertedly fixed in the boss portion in a state in which the rotational shaft is insertedly positioned in the shaft insertion hole; and a lubricating layer made of a PEEK material and formed in the shaft insertion hole or the boss portion, wherein the lubricating layer is formed by applying a liquid material to the shaft insertion hole or the boss portion.
