A bearing box for a rotating roll that delivers a high-temperature substance. The bearing box includes a bearing portion and a seal portion provided adjacent to the bearing portion and includes a first cooling liquid passage that is formed on the outer peripheral side of the bearing portion and through which a cooling liquid passes, and a second cooling liquid passage that is formed on the radially inner side relative to the first cooling liquid passage and on the outer peripheral side of the seal portion, the second cooling liquid passage communicating with the first cooling liquid passage to cause the cooling liquid to pass therethrough.

The invention relates to an infrared ray moisture meter which measures moisture of paper using absorption of infrared rays, and in which infrared rays being penetrated and scattered by the paper are sufficiently independent of whether the paper is thin or thick, in which sensitivity is high, in which attenuation of rays is small and error due to misalignment in the XY direction is small. Also, concurrently, in the invention, adverse influence due to quality of the paper is reduced by applying infrared rays which are absorbed by moisture, infrared rays which are absorbed by cellulose, and infrared rays which are not absorbed by moisture or cellulose, and by computing the value of moisture from signals detected from the application of the different infrared rays. In one embodiment a device is provided with a shielding plate having two mirrored surfaces disposed between the paper being measured and a lower one of a pair of reflectors.
