In a bearing constituted by a plural-layer slide member, the plural-layer slide member comprises a resin layer of polytetrafluoroethylene as a slide member and a backing strip to which the resin layer is bonded. A fitting hole having a depth exceeding the thickness of the resin layer is formed from the resin layer side. A temperature measuring metallic member formed of a white metal is fitted in the fitting hole. A temperature sensor is positioned within the temperature measuring metallic member. This bearing permits an accurate detection of its temperature. Further, in an oil cooled screw compressor having a bearing lubricating oil supply pipe, a slide surface of the bearing is covered with polyether ether ketone. Even if foaming occurs in the oil, it is possible to prevent the occurrence of a mechanical trouble such as galling.
