PROBLEM TO BE SOLVED: To effectively prevent seizure by exactly measuring temperature of rotating inner rings 5, 5 without employing troublesome structure such as a slip ring or telemeter. SOLUTION: An infrared radiation thermometer 24 for measuring temperature with no contact is supported and fixed penetratingly an outer ring 4. The detection surface of the infrared radiation thermometer 24 is faced the outer periphery of a spacer 9 sandwiched between the inner rings 5, 5. With this constitution, the temperature of the spacer 9 is almost equal to that of the inner rings 5, 5, thus attaining the above purpose. |
