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.
