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.

The invention discloses a bearing white metal casting segregation control device. The bearing white metal casting segregation control device comprises a centrifugal casting machine which is provided with a rotating shaft and a chuck connected with the front end of the rotating shaft, a tile body, a front end cover provided with a pouring hole and connected with the front end of the tile body, a back end cover connected with the back end of the tile body and the front end of the chuck, an adjusting base arranged on the front side of the front end cover and provided with a white metal temperature sensor opposite to the pouring hole, a cooling water nozzle set arranged on the upper side of the periphery of the tile body, an adjustment base provided with a tile body temperature sensor oppositeto the outer side of the periphery of the tile body, a rotating shaft driving and speed adjusting device provided with a servo motor, and a controller electrically connected with the white metal temperature sensor, the tile body temperature sensor, an environmental temperature sensor and the servo motor. The bearing white metal casting segregation control device cannot enable CuSn5 and SnSb compounds with high densities in molten white metal to gather and segregate to the outer side of a lining layer in the centrifugal casting process, and improves the bonding force between the white metal and the tile body and the bearing capacity of a bearing.

The invention relates to a method used for firing high temperature matte brownish red glazed porcelain in a reducing atmosphere. According to the method, in a green body and a glaze material, a common natural mineral material is mainly adopted at a certain ratio; raw materials such as glaze ash, dolomite, and white metal clay are added into the glaze material; one time firing is carried out at 1280 to 1320 DEG C in the reducing atmosphere so as to obtain the brownish red glazed porcelain. The method is capable of avoiding defects in the prior art that the glossiness of the obtained brownish red glazed porcelain is high, colour generation is nonuniform, and the primitive simplicity unique texture of Ming and Qing official ware brownish red glazed porcelain is impossible to achieve, and the method are capable of satisfying consumption requirements of returning to one's original nature of modern people. The raw materials are natural mineral raw materials, so that production cost is reduced greatly, it is beneficial for inheriting and promoting of excellent porcelain producing technology of our country, conditions are provided for improvement of the colour generation quality and stability of conventional porcelain products, and market prospect is promising.
